Mixed up Hubs - Doomed?
I got in a transaction a MTB cassette hubset made by "T-Gear". They have a
nice finish on them, and they are light, but I wonder if they are worth lacing up into a wheel. The reason I wonder is that the cassette side of the rear hub is a standard Shimano freehub. The left side has a cartridge bearing. From what I understand about bike bearings, the cup and cone bearings in the freehub need some preload. The cartridge bearing should not want any preload. This gets more complicated when the force generated by the skewer is included. So is this hub a mixed-up mess destined for an early demise? Any other similar hub designs out there? Why didn't they put cup and cone bearings on both sides? |

A small amount of preload on a cartridge bearing will not harm it, in my experience; they are designed to handle some axial loading, after all. The design may be peculiar, but I suspect they decided that it made less sense to reinvent the freehub than to simply buy a good one from Shimano and use it. -- My email address is antispammed; pull WEEDS if replying via e-mail.

Re: Mixed up Hubs - Doomed?
A design used for years by American Classic. Invariably, the cone wears
before the cartridge.
