will it work?
Will depend on mech?
can sort out a mech just want to know if the cog spacing is the same for slx 10spd cass as it is for road 10 spd cassette
ta
I've not done it myself but I'd be very surprised if it wasn't. This thread suggests the raod and mtb cassettes are different though.

I want to know this too. Might try contacting Madison tomorrow, so will let you know.
druidh - could you also ask em why/if you need a new mech to run 10sp cassette (assuming you have a new shifter), or do we already know this for schure
report on my desk by Monday dinnertime, OK !
Won't you also need to know the cable pull? Has that not changed from 9s too?
wrote that ^ poorly - I mean on mtb groupsets, not road
(either way, presumably a 10sp shifter would have the correct pull; it's just hwether the older mech would work (ie has pull ratio changed at the mech too ?))
your all nuts, plenty of people running road cassettes on mtb's - so course it works
sram red works on a mtb
dura-ace works on a mtb
all mechs will index 10 speed when coupled with the appropriate 10 speed shifter for their cable pull
ie a 2010 sram xo rear mech, will happily work with a 10 speed shifter (ie one of the modded X0 gripshifs from germany) - it however will not work with a 2011 x0 shifter as the SHIFTER pulls a different amount of cable
if you are using a short cage rear mech, then you may need to change the 11t upper pulley for a 10t in order to clear a 32t large cog on the back,
yes dirtyrider, but if the XT 10spd cassettes have different spacing to the Shimano road 10spd cassettes, then an Ultegra shifter won't mate with an XT cassette.
Shimano 9spd road cassettes are the same spacing as their 9spd mtb cassettes but we need to know if this is also true for Shimano 10spd.
You'd have thought so but Shimano have a history of such incompatibilities, and 10spd DynaSys is being marketed as all new and funky so it's possible

Existing freehubs work, mechs don't allegedly, it's a new cable pull ratio.
So you need new mech, shifters, cassette and chain, and chainrings would be ideal.

njee normally seems to know his stuff, but I'd like to hear it from Madison too
Ive heard different...... that the new 10 speed mtb stuff does work with 10sti road shifters, i hope they do anyway, as im sposed to be fitting a mech and cassette to a mates 'cross bike for the 3 peaks! will bell madison in the morning......
From what I gather-
spacing is different from Road to MTB. If you want to use this set up, get a Sram Apex cassette in the big tooth model (PG1050). This hasn't been confirmed, though, but in my head it has to be different- 10spd cassettes run a spacer on road bikes so take up a different space to 9spd.
Cable pull ratio is NOT different, but something to do with the cage and jockey wheel position is different. Sounded like not a lot of difference when it was explained to me so I'm risking normal 9spd rear mechs. This is what Madison told me a couple of weeks ago.
SRAM Apex rear mech and cassette, SRAM STI's, compact chainset, job done. I posted on that other thread as well. I tried SRAM STI's with an XO rear mech and mtb cassette - no joy!
Oh, and there seems to be more of these 3Peaks gear threads popping up now. We all getting a bit worried!
I looked at similar for a mate who was off on a round Europe trip & came across this
About 2/3rds of the way down
The Ultimate 10-Speed Touring Cassette!

My take on it was that all the SLX cassettes should work - not just this 36t dinner plate
I fully expect that although Shimano say it won't work properly (as I said above!) it'll actually be fine!
h not a 3 peaks gear thread for me this ar, mine is to pull the kiddy trailer with 2 of them in it on the cross bike and make it more off orad friendly for the lakes.
i have a 10 spd slx casette on the way, my other option is to buy a 1050 sram 10 spd apex cassette, that the same spacing as the shimano road ones then that may be easier.
or just sell the whole 10 spd drivetrain and go back to tiagra!!!
Njee- certainly agree about the rear mechs, it really does sound like an excuse to sell you a new one, it's money grabbing.
I know for a fact though, having tried it, a lot of non-shadow rear mechs won't work well with a 36T cassette though- they can't shift off that big cog properly.
As for the cassettes, the spacing is different which means it just won't work properly. I know that the Sram Apex spacing is the same though so that's the safest bet.
spokes - would a longer b-screw make any difference ?
I just noticed that on the Sheldon Brown page. Looks interesting, and having bought an XTR non shadow mech just a few months back I'll certainly be trying that.
so if a Sram apex cassette works, im assuming a 11-36 X9/X0 cassette should work, as im pretty sure Sram 10 spd road and mtb has the same spacing?
An SLX cassette is 1mm wider than an Ultegra cassette. Your Ultegra shifter won't index with the MTB cassette properly.
10 speed MTB set ups use a different cable pull ratio to 9 speed MTB and to 9 & 10 speed road. So according to Shimano an SLX 10 speed mech will not work properly with your 10 speed shifter.
Spoke to madison. it works they say.......
as i put in another post, Just sorted a Friends 'cross bike for the 3peaks after looking at the link Brant put up on a different thread, 9 spd SLX mech, XT 11-36 cassette, and 10 speed Ultegra shifters. works perfect!
9speed mech with the 32 or 34t cassette should work fine with 10s shifters from what I understand.
The incompatible bit is that the new shifters pull the same ammount of cable per shift as 9speed, its just the mech transfers this into less movement.
