Equipments

Come on, help me out on this one, I've actually brought a wrong type of cassette from eBay.
It's seem the teeth combinations are good at the time, and forgot to check the type.
Can it fit to a MTB?

The splines on the freehub body are universal between road and mountain components, so your road cassette will fit on a 8 speed compatable mountain hub. The space between the cogs is the same on an 8 speed mountain cassette as it is for an 8 speed road cassette, so your 8 speed derailleur and rear shifter will do the trick.

The only real difference between the road cassette and a mountain cassette is the number of teeth on your cogs. Your 105 is probably 12-28(?) where an 8 speed XT cassette would have been 11-30.

Thanks juba
the 105 has 13-23, my MTB has 14-34
I've look at it further, I've notice the locking ring is different as well
Are road and MTB's locking ring use the same diameter for the 'screw' part?

Though I cannot find the older 8 speed spec sheet on the Shimano website, the 9 speed 105 cassette is shown here:

Uses the standard Shimano cassette lockring. Park Tools lists all Shimano freehub cassettes as using the same tool:

Even if the lockring looks a bit different, it is still the same thread pattern/size that screws into the freehub body. Some of the lockrings have a lower profile for a different sized smallest cog.

I have to say though, a 13-23 gear range is pretty tight for mountain bike applications. Cadence is the name of the game for road riding, that is why the gear range is so tight. Most touring bikes are even set up with a triple ring in the front and at least a 12-28 in the back and that is technically road riding as well.
