FAQ

Does mud get stuck inside the relieved design of the KH-1?

Actually, although you think it would, it hasn't proved to be an issue at all. When the wheel is rotating, spokes are spinning by hundreds of times a minute and act as a shield to block out any debris. Have we got dirt on them? Yes. Does it wash right out? Yes. Is the amount of dirt accumulated less than the weight that the cutouts save? Most likely. We will do some formal testing on that soon...

 

Is the cassette included of the KH-1?

No, the price of a SRAM XX or XX1 cassette is not included in the cost of the hub. But the cost of reworking to fit on our hubs is. If you have an existing cassette, send it in and we will modify it. Or, buy one from us for the MSRP of a SRAM one.

 

Do you make a downhill hub?

Not currently, but they are in the works!

 

Which axle systems do the hubs support?

All mountain bike hubs support quick release and 15mm through axle front, rear hubs support 135mm standard quick release and 142x12mm through axle standards. They are easily converted through a simple end cap swap using the same axle. Your choice of end caps is available at time of purchase. We do not have a 150mm rear hub or a 20mm through axle front hub at this time.

 

What size cog sets do you have do you have that work with the KH-1 hub? 

Currently we offer 10 speed 11-36 mountain bike cog sets. They work with both Shimano and SRAM 10 speed drivetrains. 

We also support the SRAM XX1 10-42 drivetrain system

 

What does the hub sound like?


 


Do you have a max rider weight?

Our hubs do not have a maximum rider weight. The maximum rider weight for rims is 225 lbs.

 

Are your hubs 11 speed compatible?

Yes, all hubs are 11 speed compatible. The KH-1 can use the SRAM XX1/XO1 10-42 cassettes or a XX 11-36 10 speed cassette.
The KH-1.5 and KH-2 are 11 and 10 speed Shimano/SRAM free hub body compatible as well as SRAM XX1/XO1/X1 compatible with the XD Driver Body option. A 1.8mm spacer is required to run 10 speed cassettes on the 11 speed freehub body, not included.

 

Do you offer a through axle disc hub compatible with 11 speed for cyclo-cross?

Yes! Both our KH-1.5 and KH-2 are quick release and through axle disc brake 11 or 10 speed compatible.

 

What kind of bearings do you use?

All bearings are high quality Enduro Bearings.

Front hubs utilize 2x 71803 Enduro angular contact bearings.

Rear drive side wheel bearing is an Enduro 71903, rear non-drive side wheel bearing is an Enduro 71803 and the small cassette carrier bearing is an Enduro 6803. The angular contact bearings mimic a cup and cone system and offer complete ball contact for longer life while still having the advantages of a fully enclosed cartridge bearing.

 

Are the hub bearings adjustable?

Yes, front and rear hubs have adjustable pre-load. The non-drive side of the axle has an adjustable bearing pre-load collar with a 1.5mm hex head bolt. Loosen the hex bolt and tighten the load collar clockwise to contact the inner bearing race. Only a very light load is required, 7 in-lbs to be exact. Tighten the load collar until you feel contact and back it off about an eighth of a turn. The bearings should spin freely and not have any play. Excess load will cause bearings to wear prematurely. It's better to live with a tiny amount of play than to over tighten causing increased drag and shorter life.
