[Closed] Bodge tech question 9 speed / 10 speed

Here is the set up I have a question on :

10 speed shifters, chainset, cassette and chain but with 9 speed front and real derailieurs. On the basis the derailiuer movement will be governed by the 10 speed shifters , this should work , or not ? Maybe some different jockey wheels ?

Any thoughts gratefully accepted !

9 speed MTB Shimano rear mechs do not work with 10 speed MTB Shimano shifters.

apology for slight threadjack, but anyone know if 10 speed c/set will run with 9 speed mech/chain ?

Yep, chain/rings are cross compatible no problem.

As per Mister P, neither SRAM nor Shimano MTB components are 9/10 compatible. Shimano road 10 speed shifters can be used with a 9 speed rear mech though.

you can use the flat bar road shifters with a 9 speed rear mech if you want to keep rapid rise.

I managed to get a set for £25 on ebay but the price is very variable

Quite like that name for a light engineering firm: BodgeTech Solutions Ltd.

What exactly is not compatible though ?

scu98rkr - can you show me the shifters you mean ? Sounds an interesting option, as I like Rapid Rise.

Is it these ones ?

One click at shifter will not equal one sprocket on cassette. How incompatible do you want it?!

Those are the shifters yes.

[i]What exactly is not compatible though ?[/i]

The rear mech is not compatible with the shifters. The front mech will work although may not be 100% perfect.

You could get the 10 speed road version of the shifters...

[u]So it must be to do with lever ratio's at the rear mech then[/u] ?

As the cable pull is determined by the shifter, so if the ratio's were the same, there would not be any reason why you couldn't run a 9 speed rear mech with a 10 speed shifter as the overall travel is the same ie still the same width cassette/lateral distance between the biggest and smallest sprocket is still the same. ????

You have pretty much answered your own question there. 9 and 10 use differing cable pull ratios.
