Waiting to go on a new build, I have 10-speed drivechain apart from front mech. Rear mech, both shifters, triple crankset are 3x10 SLX.
Will my current 9-speed SLX triple front mech be ok? I guess if there was any strange reach issue, I wouldn't mind running it as a double. Not a huge deal but the mech is unused and would be a waste if I then bought a 10-speed one.
Cheers.
Can't see why it won't work, i may be about to be proved wrong but it just shifts the chain up and down a bit
yeah, thanks, I am guessing that it is just marketing (calling front mechs 9 or 10 speed) but worried that the internal mech size would be different (due to differnt width chains), or such like
it will work so long as the shifter is 9sp also. you shouldnt have an issue running the narrower 10sp chain through the front mech. for years i used a 9 sp front mech on an otherwise 8sp transmission without any problems
I set up a 10spd setup with a 9spd SLX front mech the other day, it was fine.
It will be fine. I recently went from 3x8 to 2x10 using the same 9sp triple XT front mech and it doesn't rub and shifts fine (although a 2x10 mech would be better) so you'll have no problem at all. All left hand front mech shifters are the same cable pull so it doesn't matter what shifter you use with what mech.
Thanks everyone. Although that does mean that I now don't get to buy a shiny new trinket 😳
ummm OP your staying with 3 up front?
i had some issues with triple up front shifts , double up front was fine, but triple had issue, esp. on middle down to granny.
