This was going to be another Randoms article, but it seems like 3D printed pump-holders are this year's enduro-specific socks. Everyone's making them, so this is going to feature a few of the more interesting ones.




Jank Components

Jank Components OneUp Pump Holder
Santa Cruz Glovebox pump holder for OneUp pumps.

Jank Components OneUp Pump Holder
Eric likes big layer heights.

Retention is really easy with his system. His clips are a direct replacement for OneUp as well.

We recently had Eric Olsen aka Janky Eric aka Jerrick on the Pinkbike Podcast to chat about his business—stay tuned for that, it should drop shortly. Jank's origin story is similar to a lot of 3D printing businesses—requests from friends started piling up until he had to make it happen. Everything is designed and manufactured in Bellingham, Washington, with the goal of creating a sustainable company.

As far as I know Eric produced the first SWAT box pump holder, which is a really nice way to keep your pump stowed inside your frame without rattling. He's recently carried that idea over to the Santa Cruz glovebox in-frame storage as well. It's designed for OneUp EDC pumps, weighs 15 grams without the required hardware, and works with all Santa Cruz models that have a glovebox. I'm a big fan of the concept.

3M VHB tape is incredible stuff.

Jank has also released an adhesive/ziptie mounted version of his inline OneUp EDC pump holder for frames without threaded holes.

Glovebox & Adhesive Pump Holder Details
• Designed for OneUp EDC pumps (or other 28-30mm pumps)
• Glovebox version includes hardware and is compatible with all Santa Cruz bikes with glovebox
• 3D printed with ultra strong NylonX carbon fiber filament
• 15g for the Glovebox version without hardware; 17g for the adhesive version

76 Projects

76 Projects
OneUp pump mounts, so hot right now.

76 Projects
Stick on or bolt on.
76 Projects
Ideal for under the top tube.

I've mentioned the UK's 76 Projects before. I'm a big fan of their HP multi jet fusion industrial printing setup—it's a huge investment and produces incredibly high quality nylon parts. They've recently turned their attention to an inline pump mount as well, and come up with this clever bolt on/stick on combination mount.

Details
• Fits OneUp EDC and other similarly sized pumps
• Can be bolted-on by popping out the slot covers and directly mounting to frame bosses (+-5mm)
• Can be stuck onto most bike frames with its flexible base and VHB adhesive (*flat to minimum tube diameter of 34mm)
• Printed with multi jet fusion technology in tough nylon
• 21g (plus mounting bolts)
• Designed and Manufactured in the UK
• Price: £17.50
• Available now at 76projects.com





Cycle Solvers

Cycle Solvers
More OneUp Pump Mounts!

Cycle Solvers
Run it as pump-only...
Cycle Solvers
...or use a velcro strap to fit a tube, tools, etc.

Another UK outfit called Cycle Solvers does this very clever OneUp EDC pump mount. Its claim to fame is that in addition to holding your pump, it has a gap between frame and mount for an optional velcro strap that can be used to secure a tool, C02, levers, tubes, etc.

Cycle Solvers
Clever clip

Cycle Solvers
They offer their O-ring and clip separately as a direct replacement for the OneUp clip (that does sometimes break)
Cycle Solvers
Works on a stock OneUp pump holder as well as their own inline mount.

Details
• 3D printed with a tough, UV stable material
• Standard bottle cage spacing
• Optional Velcro strap can also be used to hold a tube or tools on top of the pump
• Comes with pump mount, O-ring clip, and mounting hardware
• The tough O-ring clip is available separately and backwards compatible with the stock OneUp pump holder
• Weight TBC
• Made in the UK
• £23–£27.50
• Available now at cyclesolvers.co.uk





ProBike3D

These aren't new, but I wanted to give a quick shout out to ProBike3D, a Canadian outfit that's been doing 3D printed pump holders and GoPro mounts for a while now. They do a few sizes of mount in several colours of PETG material.

Details
• Available in black, blue, clear, red, silver, or white
• Printed with PETG
• Two sizes: 28-31mm, and 31–34mm
• Includes retaining strap
• Made in Newfoundland, Canada
• $26–$29
• Available now at probike3d.com

I printed this pump holder for a Crankbrothers Klic HV, but can do most pump sizes.

3D printed Sequence Ultralight Inline Pump Holder for OneUp Lezyne Crankbrothers More
A different size for OneUp pumps. I use the included Nano strap for the big bike.
3D printed Sequence SWAT Frame Storage Pump Holder for OneUp Lezyne Crankbrothers More
Did a SWAT version as well. Inspired by Jank, but with some key differences.

All of the above pump mounts are cool and all, but what if you want something that's more expensive? And what if you prefer things made by someone with no engineering experience? Well search no further. I've started to sell a few of these universal(ish) inline pumpholders too.

I tried to take advantage of 3D printing tech by building the model parametrically. Rather than one-size-fits-some, this let me generate individual designs for OneUp, Lezyne, Crankbrothers, Topeak, and most other popular pumps on the market. And because they're size-specific and I made the shape elliptical rather than round, pumps snap in really well.

The pump holders are light at around 10g (more for larger versions) and made with NylonX carbon filament. I use a low 0.1mm layer height for a nicer finish, because what I lack in skills I make up for in vanity. I can do custom sizes or requests (eg. strap delete if you want to live dangerously), and they start around $60 CAD (~$44 USD) with free worldwide shipping. Check out all my bad ideas here.

 Good to see pumps are making a comeback, the co2 cartridge thing seemed wasteful and inefficient.
  • 19 1
 Plus also the fact that one cartridge only gets you halfway to a full tire!
  • 16 6
 Yes, but if you love your pump, *warm climate riders beware* of those 3M-adhesive pump mounts: that tape *will* delaminate in the space of a single summer in temps over 80F. I've used it for years to keep stuff like cadence sensors from wandering, but unless you're OK with buying a new pump, sensor, etc. several times a year, you need to use 3M VHB tape in conjunction with zipties, O-rings or something else to wrap around the tube you are taping to.
  • 3 1
 @powturn: this is good to know! Hence why I made mine use a combo of zip tie and/or vhb tape
  • 20 0
 @powturn: if yours delaminates that fast, you’re using it wrong. I used to live in Vegas and have used 3M tape to adhere body panels, including VHB, and it never failed even sitting outside in 110+ degree weather. VHB is absurdly strong.

Either you’re getting a knock-off VHB or you’re not prepping the surface properly, and that’s not the fault of the tape.
  • 12 0
 @ericolsen: don’t listen to him. This stuff has been around for a long time and has been used for things far more vigorous that mountain biking, such as MX and trophy truck racing.
If it fails, it’s almost always because of user error.

 @nickfranko: Mea culpa: just checked & tape I've been using is 3M Extreme 30lb acrylic adhesive tape. I had been told it is essentially consumer market version of VHB though, is that not the case? Just double checked spec sheets of Extreme 30lb vs 3M VHB GPH-160GF: density, peel adhesion, sheer strength, & temp range are all nearly identical. My surfaces are always prepped w/ isopropyl as per 3M instructions. If there is something I"m missing about the differences between these seemingly identical 3M acrylic tapes, I'm genuinely eager to learn. Thoughts?
  • 12 0
 @nickfranko: if only there was a way you could bolt a pump holder to your bike.
  • 4 0
 @ericolsen: most badges and body trim panels on OEM cars and trucks are held on with this stuff. Hell I use it to hold an esc for 1/8 scale to my RC . That esc regularly hits 100c and it doesn't come unglued. Prep and handling is important along with constant pressure for up to at least 30 seconds when installing. Surface finishes and materials can effect its performance as well, I use VHB regularly and only have issues when I rush and don't prep and apply pressure properly. The bond increases with time as well. Don't trust any other double sided tape
  • 4 0
 @powturn: I found that 1 inch of vhb holds 3 lbs and 1 inch of Extreme holds .5lbs. Huge difference.

 @MikeGruhler: Thanks for insight. Which VHB variant would you use for cycling applications, which typically involve bonding plastic to a painted surface? Do you know of a good source for ordering smaller quantities for a home shop?

  • 9 0
 Definitely ticks all the boxes.
  • 3 6
 Except the lack of a lever to release the pump from the valve. So many skinned knuckles or bent valve cores forcing it on and off.
  • 16 1
 @BrianColes: Years of roadie group riding, seeing all manner of choppers trying to operate mini pumps, has led me to believe three things:

1) All pumps should have a little flexi hose to stop the valve core getting bent.
2) No pump should screw onto the valve or it will inevitably unscrew the core after you've spent ten minutes pumping it up.
3) The need for 1 and 2 could be completely removed if we just switched back to schrader valves. Plus you can remove the cores to stick sealant in.
  • 2 0
 @Woody25: I had a Lezyne with a screw on flexy hose. Way too much faffing with that pump and the one or two times it unscrewed my valve core made me get rid of it.

I’m down for Schraeder or just a locking lever on my presets pump.
  • 3 0
 Love mine but I can't get it to stop rattling. I use the 76 projects inline holder but it still rattles like crazy. I tried taping the top cap down to see that helped but to no avail.
  • 3 0
 @tbc: mine rattled until I put a line of insulation tape on the tyre lever/tool holder between the lever and the tool. Now it holds the tool snug and doesn't rattle any more.
  • 2 0
 I've been envying the OneUp pump, but my Topeak Mountain Morph pump is just too good. However it is ENORMOUS.

It has the flex hose to go to the valve stem, a lever to grab/release the valve stem, a fold out base to put your foot on, and a locking pump handle that turns 90* when you go to use it. I keep it on my frame, but the thing is basically half a floor pump. It works incredibly well though. I also spray painted mine black because the stainless and black look didn't do it for me.

 @BrianColes: Just go Fillmore valves - core isn't removable! Problem solved, and they're high flow.
  • 1 0
 @Woody25: Not to sound shill-ish but I've had those same issues with presta and went with the new reserve valves. Seem to be plenty robust over a year of use (use pump on every ride) and its cool dropping pressure via unscrewing the cap and tapping.
  • 1 0
 @KolaPanda: Yeah, I'm with you, I gave in and got a set of those too! I haven't installed them yet, but they do seem like a better presta. I just resent paying all that money when it seems like the larger diameter schrader would have been a better solution for tubeless all along, especially now rims are so much wider.
  • 24 0
 I prefer to use a Lezyne pump so that after pumping 300 pumps to get my tire presurized ,I can remove the pump and my valve core at the same time...very satisfying
  • 5 0
 god damn you, that is too funny. Brings memories pumpin my fat tire ( not 300 but maybe like 50 pumps) in freezing cold and then removing core ahahahahaha. Solution is a little of grease on the o - ring
  • 3 0
 @valrock: nice tip.. Im doing that. put a drop of locktight on the core as well.
  • 1 0
 The last time I used a Lezyne/Silca style pump to inflate my tires I had to then use a C02 on the start line because I didn't notice the pump had partially unthreaded my valve core. Never again... Cheapo Walmart pumps work great.

 I use a back pack. One I’ve had for more than 15 years. It’s tattered and kinda smelly. I can carry water in it. All of my tool kit, pump, tube, and A snack for bigger days, the list of stuff I can put in that thing goes on and on. Its survived numerous wrecks. It fits every bike I’ve ever had. If I hold onto it long enough it will be fashionable again!

 What are the chances of ripping off the paint when removing the stick on pump attachment? That VHB tape is the same stuff used to keep trim on a car. I’ve seen chunks of paint come off when removing the paint protection film from frames.

 I also wonder about the OneUp pump and gloveboxes in general. I love my OneUp Pump and Jank holder on one bike, but have a SC with a glovebox coming and going to use my pack tools, pump, etc. in it because each of them is better (and should be) than the OneUp integrated / space saving solution.

 I like the Matterhackers ones, which are fancier Prusa clones. From what I've heard the Prusas are great. Our podcast with OutsideBrendan and Janky Eric drops this week I think, and they had some other suggestions for beginner machines I've struggling to remember right now.
  • 1 0
 I love this idea but want something burlier. I donated my One Up pump to the trail at the end of a 14 hr memorial ride a month ago in an awkward fall in the dark. My own fault as the dainty rubber band broke months ago and I never bothered replacing it. The One up pump holder is the only downside to that tool. I don't figure I'll ever know the point of in frame storage as I can't justify dropping the cash on a new bike that has one.
  • 2 1
 Argh that sucks. I believe all of these holders use a stronger O-ring or strap than the stock OneUp one. The Cycle Solvers and Jank ones are direct replacements for the stock O-ring as well, if you don’t want an in-line pump holder.
  • 2 0
 I've designed an inline side loading OneUp pump holder with integral split link storage. Since I'm a pessimist I opted for a full wrap velcro strap to secure the pump into the holder and not rely on mechanical strength of either an o ring or the print. I've had a few huge crashes this year, unfortunately, but it's been great product testing. Pump hasn't moved at all. As for my wrist, back, pedal and helmet I think I'll need to print some replacements!

 Too funny, pumps on the frame, how old school!

I carry my stuff on my back or hip, why you ask? Because I want my back to be a light and agile as possible.

It’s like folks wanna drive a Sprinter, and then get to the trail and ride their Sprinter Wink

Minimalist is the way to go!

 Good to see the crank brothers Gem pump out there, which is small, efficient and pretty and pretty clever.

@ProBike3d:
I'd like to have the thing of picture nr. 16 (top down) 3d-printed, that prevents the pump head from rotating.
Did you do that?
  • 1 0
 Hey, this is Josh from ProBike3D. The part you're refferring to is 3d printed, and was made up quickly to be a temporary fix. I'm working on a long term solution that should be available soon. I agree with you 100% about the Gem, it's a solid little pump. Just not the best suited to be frame mounted on an mtb in its stock form haha.
  • 1 0
 @JLewiMTB: that's awesome. Did you do a replacement cap that threads onto the pump barrel? Let me know once you release that, I'd love to check it out.

Here's a freebie if you want to mount an EDC pump inline in the frame and don't mind strapping the mount to the frame (with an EDC strap). If you have access to a printer.

 Do any of these solve the rattly pump problem? I've got a OneUp pump and have narrowed it down as the "one thing" on my bike that makes noise on descents. It is the tool insert rattling inside the pump. The original pump mount flexes so much too, even when mounted as close to the bottle cage as possible.

I have started carrying the pump in my hip pack to avoid the noise.

 Had the same problem. Put a very small strip of cut up inner tube on one end of the tool to keep it quiet. Fiddly solve but works for me.

 For Gosh sakes someone 3D print the removable closure on the OneUp pumps with TWO tabs to revove the cap straight off. Use to have to beat mine on rocks to remove the cap and finally just through it away over this. Just could not remove the cap in a pinch.

 If you actually have to use a pump those Lezyne ones that are like a mini floor pump are unbeatable. The hose connection pretty much eliminates any chance of damaging the valve stem, which, in my experience, is common when you're yarding on a mini pump directly connected to it. I also have bad shoulder problems and putting the pump on the ground let's you use a cpr motion. It's much easier than squeezing your hands together.
  • 1 0
 with a regular mini pump, just put the valve at top, sit on the tire and pump away. No way any physical limitations are stopping any of us from that motion.
  • 1 0
 @Weens: What you are describing is 20 times as hard as using the Lezyne pump. I'm a 64 year old guy with 6 shoulder surgeries (so far). Even a little bit easier pumping motion would be worth it, and those Lezyne's make a huge difference. I'd highly recommend trying one.

Currently still use the dakine hot laps for just phone, and since i have the pack, I carry multi tool, pump ect in there.

 The problem is it sucks to see your designs get printed badly, and there's always a risk of your products being knocked off. But I do think it might be worth experimenting with a digital download. Also, a few of us have been chatting about printing each others' designs locally to reduce shipping impacts and costs. It's a bit of a logistical shitshow, but I think it'd be great to get some sort of collective together for this.
  • 1 0
 @brianpark: This is such a great idea. Some kind of global 3D printing collective and a map to show your 'friendly local MTB printshop' where you can collect your locally printed components. Maybe some sort of franchise model to buy-into a library of designs to print locally. Or the 'no dig, no ride' philosophy, where you can have access to a 3D model library, provided you upload your own designs too... lots to consider.

 Many would do well to look at the past and history, before declaring themselves innovators, these pump holders I had the SAME in 2005 and they cost the same but with the pump! Ridiculous.

 Hey, Eric from Jank here. I’d be the first one to tell you that these products are stupid. But nobody made these holders for the ubiquitous OneUp pump so I met the demand. Im curious what pump you had back in 2005 with an inline mount?

 @ericolsen: from 2005 to today I will have spent € 30,000 on bikes and equipment, I don't remember the brand, but it was the same, trust me. Then I didn't say stupid, but ridiculous. It is ridiculous that to make an object "cool" just because it is made in 3D, energy is wasted instead of making it in the traditional way at a tenth of the cost.

 @pk71: I don’t think these products are cool because they are 3d printed. The problem is that making it the “traditional” way means tooling a multi-thousand dollar injection mold in Taiwan or China. Then making 10000 parts and shipping them across the ocean. Not very environmentally friendly. The “traditional” method is not an efficient way to make niche bike parts.

 If you can do better then by all means, create a cheaper alternative and put Jank out of business.

 @brianpark that's what you call a shameless plug I assume ? There's probably an element of coolness I don't get, but it feels really weird to see a Pinkbike journalist selling his own stuff in an article he wrote himself

 Ehhh yeah to be honest I was leery about including myself. Unlike the rest of these very talented folks it’s not a business for me, just some insomnia-driven garage tinkering for my sanity. I’m not in it for the money, but I do want to show off what I’ve been working on and thought this would be a good place for it. I dunno, let me know what you think.

 @brianpark: Well I for one really enjoy seeing these small enterprises making interesting niche products!
The world of 3D printing is so full of 'trinkets' that I get really tired being of the forums/newsgroups so this is quite refreshing and inspiring!

 Does the swat box jank mount use the bottle cage holes? Or just adhesive?
  • 2 0
 Jank's SWAT box uses bottle cage bolts and the original square nut to attach a two-piece holder. I'm not sure how his Glovebox version is connected.
  • 1 0
 Swat box pump holder uses the stock hardware. The glovebox version includes longer hardware that replaces the short screws on the bottom of the glovebox.

 How has nobody noticed the prices they are charging for 3d printed items that are really fragile and cost nothing to make?
  • 2 0
 Value is always subjective, but if they're made right, 3D printed plastic parts shouldn't be fragile. PLA is weak in the sun, but things made from PETG and Nylon should be plenty strong as bike accessories. And honestly for value, it may just cost a few dollars to print a part, but that's the same for injection molded mass production. Each injection molded part costs only pennies to actually produce, it's just got high setup cost times and overhead.

 Ffs, not everything needs to be 3D printed!
  • 3 0
 I actually agree! The point is that you can iterate quickly and do niche stuff. I don’t think anyone making mass produced versions of any of these things yet, but I’ll be happy to see it.

 Absolutely right. Not everything.

But I've made fully functional usable parts and tools on my sub £200 printer. How much would a set of machines cost me to turn, mill and mould these lots volume quick turnaround items?
  • 3 0
 Agreed... but the alternative is that none of these useful, but niche products would exist otherwise. Spending thousands on injection mould tooling for a few hundred parts doesn't make any sense. Enter: 3D printing to fill the gap.

If OneUp thought there was a business case for selling an inline pump mount, it would probably be for sale by now. That tells you everything you need to know about how 3D printing fills the viability gap
