10 speed compatability
can you use a 9 speed crank with a 10 speed chain and casette.
Can you use a 9 speed R mech with a 10 speed chain?
can you use a 10 speed crank with 9 speed system.
looking to change my crank and do not know if i can upgrade to 10 speed crank but keep the rest as 9 speed for now.
why would a 9 speed r mech not work, spread must be the same, or is it just an issue with the jockey wheels and the width of the chain?

didn't make that much sense to me, yes the chains are different widths, so i do not see why a nine speed hain that is slighlty wider whould not work on the cranks.
anyone any experiance of this ?

The rings on a 10 speed are slightly closer together so if you are using a 9 speed chain you may get some rub of the chain on the adjacent rings when in extreme gears. Other than that it works fine.
A 9 speed rear mech won't work on a 10 speed system because the cable pull is different between 9 and 10 speed.

It is not as simple as the amount of cable each click on the shifter moves. The distance the mech moves per mm of cable pull also changes. So no, 9 speed and 10 speed don't mix properly. Trust me.

I'm running an 8sp Sora Shifter on a 10sp 105 Mech it's a bodge but it changes gears!

That is road stuff though BHB. You can mix 8,9 and 10 in road because the cable pull ratio is all the same.

You are quite right Mr B but at work we put a 9spd Shimano casette on a 10 speed Shimano MTB drivetrain and shifters and it indexed fine much to our surprise .
