Shimano FH-M756L XT Rear Disc Hub (32H Rear 6-Bolt Disc)

I'm 99% positive the 2012 trek 8.3s came with the FH-M756L XT for the rear hub.
Been successful using the stock hub and am piecing together a spare wheel assembly. Is it good to continue with that model or should i consider a different hub? Keep in mind i already have the new cassette and a new derailleur with a new disc rotor. I will need to maintain the fitment to marry them all together.

Only part i have not bought yet are spokes, but i do have about a dozen spare ones for those times in need that'll be put to use if i stay oem length.

Thanks in advance!

any disc type 8-9-10 speed rear hub of a shimano compatible type will work...

if you are wanting use the "spare spokes", and a similar rim, then you should get another hub and rim like the ones on your old wheel assy..... the hub is still available. can't be certain about the rim, but it probably still available, too.

the HUB should have the Shimano XT logo on it, if indeed it's a shimano XT that is on your bike.
Trek sources a lot of it's hubs from Formula on it's lower end bikes, btw... jus' sayin'.... they have no logo, or are labeled Bontrager.... usually....

Getting home and upon visual inspection as well as paperwork, Shimano Deore XT FH-M756-L is the OEM rear hub. Does the XT mean anything or is that "XT" the same hub as my "L" ?

*What I do not have right now is the hub (the topic for discussion) .

What I have partial of [should I choose to use them or not] are a handful of spokes that were just for spares in case I ever needed them (which came in handy at times) .


So with that said, I have everything else, even down to the rubbers. Just need to ID a hub that isnt poor reputation based on proven experiences. Formula-D has had many problems in the hub world when it comes to production issued and warranty replacement parts from what I read.

Appreciate the response.

I'm not sure what the "L" means, but it should be identical to this:

I have built wheels and ridden with Shimano hubs for many years. The only malfunctions that I've had were caused by my own mechanical malpractice. If this is for a "spare" wheel, I will bet that you will hand it down to your grandchildren.

Maybe the hub is strong, spokes not in my case...

And how dare you wish such a vain future!

Ordered the hub.
Shimano:
FH-M756L XT Disc Hub 32 Rear 6-Bolt
Instead of going 32T i went with a CS-HG31 Hyperglide Cassette 11-30T for the paved flats in the city commute. Having a hard time finding spokes.
The lbs might have them readily available and it might be best to have them set it up. I do like to support my lbs if i can.

Sourcing spokes is no problem. Typical J-bend for this hub. A couple simple hub and ERD measurements plugged into a spoke length calculator will give you the length.


You didn't mention your choice of rim.
