Dedicated 7 SpeedAtomlab is stoked to announce the addition of the DHR 7spd hub. The shorter freehub body allows the drive side flange to be wider spaced from the non-drive flange; as a result, a stronger wheel with more symmetrical spoke angles can be built. This increased triangulation of the spokes increases stiffness, especially important when using a larger wheel than 26".
The flange spacing is highly visible between a standard 150mm hub and the DHR hub.
Short ShiftThe 7 speeds of the DHR hub can typically be covered with a two tooth jump between each sprocket. The DHR hub offers an even shift between gears when using a 10 speed 11-34t cassette for a 11 - 13 - 15 - 17 - 19 - 21 - 23 spread. 11-24 and 11-25 spreads are also possible. Installation is a breeze. Simply remove the three largest cogs (
fixed to a spider) from a 10 speed cassette, slide the remaining seven cogs on the freehub, torque the lock ring, limit your 10 speed derailleur, and go shred!
No spacers, a true 7 speed hub.

I'll stick with old school 8 speed cassettes on my DH rig for now. Sure would be nice if there was a company that could man up and build me a clutch derailleur for it!
Never heard of these guys but if they're solid, that's just what it costs for a decent hub.
On a somewhat related topic, I would confidently state that a "fancy" FRONT HUB ia probably one of the most overpriced items out there. For what is essentially a cylinder with bearings pressed into it I buy pretty much the cheapest one I can get my hands on and have yet to encounter a problem : )
Example I heard this qoute the other day so Im using it here, if the industry feeds u hamburgers you will eat hamburgers! reality here is many consumers hate what the industry feeds us, and Atomlab u hit the nail on the head, cheers, if I was building up a new Dh wheelset right now this hub would be high on my list, I support those who listen to our needs, thats how you grow business, not by forcing new standards that are different than what we have now for no real tangible benefit to the average consumer, I doubt most people could benefit from Specialised 142+ plus std or Treks std or Srams new std over the normal we have 20mm, 110, 135, I have bought into 142 for example because the DT axle system especially has made wheel removal and installation a cinch.
In srams defense, XX1 or 11 spd std as another example has been a new standard that is entirely new if people would take time to use it and understand it, its a no brainer, but not something that wasnt asked for over many years and ignored, so good on them for that, same with fork Pike a reliable and high performing fork (Fox how many years and if not for the Pike we would still be feed the same hamburger mentalitly garbage) stiff legs, shite dampers!
So long way round but this is something real world for real riders to me that makes good sense, thank you atom lab.
Sram = Fail
And Atomlab have kindly made sure it fits a shortened 7spd block, without any funny spacers or whatever. I assume...
Touché.

if you can argue for 7 speed, surely nobody will NEED that extra 1 gear down to a 6 cog setup...
edit i am agreeing with you
My wheels are fine. My hubs are nearly fine. They just need steel free hub bodies for dh. My wheel diameter is fine. My hub width is fine.
now invent a perfect hub/cassette for trail riding. Has the lower 7 of a dh cassette. The next 3 are obviously larger for climbing and and the outer has a planetary gear for an overdrive for steep climbs.
The value you put on it probably depends on how hard you are on rear wheels. As you apparently never have an issue, it's probably not for you.
BTW wider flanges add only lateral stiffness, 36 spokes add both lateral and vertical, making them too stiff vertically... whiiiiiich is a bullcrap because everyone wants carbon rims and those are stiff as FK!!! Asymmetric rims like Ryde or Bontragers, solve flange problem to a certain degree.
Disappointed by their rims. First and last product I ever bought from them.
This is getting filed in the "White Crayon" bin.
