We're back on Vancouver's famous North Shore for another Daily Driver Bike Checks! This time Christina headed to Mount Seymour to find out which bikes the Seymour locals are riding.
0:42 - Commencal Meta AM 2:09 - Norco Range 4:51 - Specialized Status 6:46 - Ibis Ripmo 9:03 - Rocky Mountain Altitude 10:23 - Transition Spire
Something that confuses me is how high-pivots achieve such low levels of kickback while retaining similar levels of anti-squat to non-high pivot bikes. I get the 'if you didn't have the idler on the high pivot, you'd have insane levels of pedal kick' argument. What I don't get is the anti-squat and pedal kick seem to scale differently on an idler bike to a non-idler
hahah I DID!!! Hold your horses! Not every second of our 20min chats make it to the final cuts, sorry! I have a feeling Andrea will be here after his Dawn Patrol ride to chat all about his bike if anyone else has questions or concerns
@mattg95: generally, anti squat is a function of chain line and pivot/instant-center location. On a high pivot bike, anti squat is dominated by the pivot location, and the chain line is moved by the idler to a position such that it’s effect on anti squat is relatively low. Additionally, the chain length is very close to constant on high-single-pivot-idler bikes (because of the idler), so as the suspension compresses, the chain does not need to “stretch” between the crank and the cassette, meaning your crank doesn’t have to rotate to account for the “stretch” (since chains don’t really stretch, either the cassette or cranks must rotate to account for any required additional chain length between the cassette and chainring during suspension compression). Hopefully that’s helpful?
@mtbikesince87: Going out on a limb but it looked like the purple bag maybe just held goggles (from the shape)?
Seems like a smart play actually, keeps them dry and out of the way for the climb but easy access for the descents. I sometimes bring my pack only because I want my goggles.... Handlebar bag play eliminates that need.
@dresendsit: Yes, it might be the case. And it probably still has non zero kickback anyway (it's a horst link so it has virtual pivot point which migrates during compression, so the idler is not exactly in that exact point). But then what is the point of Onyx hub when using Ochain, you simply loose instant angagement ... Maybe just for the silence.
Probably in response to that Onyx hub he's running. The HP takes care of most of it, but I can see an O-Chain being useful if you have a really high (or instant) engagement hub.
@pb-kg: so what you guys are telling here is that people actually build wheels with extra fancy, extra expensive instant engagement hubs, just to reduce that instancy by putting things like o-chain (for even more money) so that it doesn't interfere with suspension?
How about adding to this
how about a full day survey off video
Get a much bigger survey
Get the unpaid intern to do it.
Offer free pb stickers to riders who do the survey
@mattg95: the component of anti squat that nobody talks about is the acceleration forces that a rear wheel drive vehicle places on the rear axle, and therefore the rear suspension system.
With the main pivot above the front/rear axle centerline, acceleration forces on the rear axle will cause the rear suspension system-and shock-to extend. If the main pivot was below the axle centerline, acceleration forces would cause the suspension system to compress.
"Low pivot" bikes have a main pivot that is still above the axle centerline but it is the degree to which the main pivot is above the centerline that will determine that amount of accelerative anti squat that the system sees.
@akkwlsk: I dunno, for me the bigger selling point on the Onyx hubs is the fact that they’re completely silent and have less drag than any other hub. Engagement is cool when you can get it but it doesn’t trump the other factors, especially if you don’t like kickback since the instant engagement is a negative there. That said, having owned a Range, I don’t think the bike really needs an O Chain.
How many people commenting have actually used the ochain? I have one on my high pivot supreme dh and low pivot meta sx. Both rear suspensions works better than without the ochain but the meta is more noticeable. If you have ever run a supreme or any other high pivot chainless, you would know the chain influences the suspension on these bikes. My 2 cents.
@mgs781HD: I do in my TR11, and the suspension feels way smoother, with just a little or non crank kickback, for sure all bikes are different, but it is funny that this iddler bike needs a O-chain to do what this bike claims to do without one...just saying..
@mgs781HD: Funny, I was thinking the same thing. Pretty sure the whole Spec enduro team (Kelly, Keller, Sedlak, Snow, Murdock) is rocking them this year, or at least a few of them were in that Vital vid from a few weeks ago. Guessing they wouldn't be if it wasn't helping... www.youtube.com/watch?v=LTZ1VytZSD0
@felipebikeandgo: I think the high pivot and idler claims are more for the pedaling efficiency than suspension performance while coasting. I'm not saying that my supreme needs the ochain but I do think it benefits from having one. Basically kick back happens due to chain growth, regardless of the design. The supreme has a lot of chain growth and the ochain reduces it a little.
@mgs781HD: No, only the upper chain growth produces kickback and the idler is there precisely to reduce it to almost zero. So what high pivot does is a better axle path and little kickback.
i'd like to see how the guy on the Status rides. everyone else is got their tires down to the min (same here) and one guy is riding 30 psi in the rear, in the rain, on the shore. either he's doing it wrong or he's a beast shredder.
From Bromont actually, and yeah we re french canadian. First time ridind the shore, this place is awsome! Boogieman is my highlight I think... and soory for the "medical kit" haha! never had to use this shit yet but hey... I gotta fill that bag with everything I think of or things inside will rattle like crazy. Truly cant figure out how that guy with the stem bag doe..?
@rrolly: whoa whoa whoa are you calling truck nuts "hitch nuts" now? The only people with truck nuts I've seen have been overly truckish...the earnest ones, at least. If truck nuts have, uh, trickled down into the merely hitched populace, i'm panicked for sure
@KadeStoltz thanks for asking, hoping for next week. Stoked to get it out, currently swinging the axe through a dangerously large amount of footage from all those races
Do Canadians typically use imperial measurements in conversation? Several people using pounds and feet and I didn't expect it. Maybe this is just a mountain biker thing since we like to mix metric and imperial on bikes lol!
All Canadians do this. Distance is in kilometres. We don't understand miles at all. Speed is in km/h.
But height of a person is in feet and inches. Weight of a person or a bike is in pounds. Area of a building is in sq. ft. It makes zero sense but that's just how it is.
We are wildly inconsistent with our application of the metric system. Most of us don't know our own heights or weights in metric. Our body temperature and our ovens are usually farenheit, even though we have no clue what temperature water freezes or boils at in °F. We measure distance in metric, except for in construction where a standard door is still 6'8" tall and a 2x4 is still only 1-3/4" thick. So we don't bat an eye at a bike with a reach of 480mm weighing 31.5 lbs!
Oven temps for cooking are Fahrenheit. Outside temperature is in Celcius, we wouldn't be able to tell you what 70º weather felt like. It's completely bonkers and no one cares or questions it at all.
Great insight into the mix of measurements in our beloved northern neighbor. At least y'all aren't stuck in the painfully nonsensical imperial system for everything like we are down here.
@noahferg: Depends, when you're married with a Canadian woman and living in France, at the beginning it can be a big mess these two units... You end up with a post-it on the oven to convert F to Celsius so you can it something not burnt. Or the problem with the scale to know how much you weight. And me as a good french, got an app to convert different unit so I dont get list too much. And for cooking, you end up with the cup system and tea spoon and table spoon because your cooking book are In English and there is no simple way to convert a cup of floor in grams. But after a few years, you get use to it... Still need the multi converter time t9 time.
@jbravo: I think a lot of that is convenience though due to trade and relations with the states. We overlap culturally and commercially a lot. Take mountain biking for example- a lot of that early development was in the states via Specialized, Trek etc. so lots of those measurements stuck around. Mentally- the metric system makes more sense across the board IMO but yeah... I couldn't tell you my height and weight in it as the language most familiar likely overlaps from American culture.
@snl1200: Great points and I, for one, am happy that we in the US PNW do overlap with BC as much as we do. (And that relationship will grow stronger in the next few decades, but that's another topic.) One thing about growing up on the imperial system island is I have learned many conversions and, I really hope, keep my brain exercised translating between the two as my wife is French and her family is far removed from the imperial system.
Just curious, @christinachappetta, how tall are you? I'm 5'-2", so no shame if you're short like me! You just looked particularly short next to the 6' guy
Nice to see the Ochain in the wild. Now if they just find a way to change the design so it locks engagement while starting to pedal and then frees up when not pedaling it would be perfect
We make those articles too. Feel free to click on those links any time...ever! But my job is specifically video related so if you see my face or name, maybe it's not for you :-) and that's ok!
just came here to troll the guy with the Range, as someone already pointed out the onyx hubs have a sprag clutch not magnetic pawls, he’s confusing it with a Projects 321. At 140 pounds he definitely doesn’t need 23 psi in double down tires. His computer tells him what gear he’s in lol, Mechanical shifters above the LX level have not had gear indicators for years because nobody needs them. You can feel what year your bike is in, who looks back at their cassette to figure out what gear there in when you’re mountain biking lolol. that purple bag hanging off the stem must make such a racket when you’re going downhill I can’t imagine riding with that swinging around on the handlebar. Lastly his whole Dawn patrol thing about trying to limit exposure to Covid while mountain biking in the woods made his whole bike set up make perfect sense
Ok I'll give you the electronic gear display thing. So flipping useless. I have it on my XC race bike. Never look down at it. Half the time it doesn't even connect and I have an irksome void on my screen where it's supposed to be.

Yeeeeeaaaaaahh that's some dentist level shite!

Also don't run inserts and don't want the hassle of them. Some people weigh 220 lbs (me) and ride fast !
