Does mud get stuck inside the relieved design?
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?
No, the price of a SRAM XX, XX1 or Red 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 or fat bike version?
Not currently, but they are in the works!
What size cog sets do you have do you have that work with the KH1 hub?
Currently we offer 10 speed 11-36 or 11-32 mountain bike cog sets, 9 speed 11-32 mountain bike cog sets and 11-25/26/28 road cog sets. They work with both Shimano and SRAM 10 speed drivetrains.
We do support the SRAM XX1 10-42 drivetrain system
What does the hub sound like?
