10sp front with an 11sp on the back?

dermabrasion

Anyone changed to an 11sp rear mech, cassette, right STI and chain, while leaving the front in its original 10sp mech and chainring and left STI.
I read a piece by Leonard Zinn in Velonews to say this is do-able. Like to know if anyone has done this. It'd be cheaper than a whole new groupset.

You'd be doing well to buy a single shifter, and 11s front mechs are a lot different to 10s ones.

You would need 11s shifters and mechs, and an 11s cassette. Also an 11s chain.

A 10s chainset will work fine. Brakes are supposedly a different pull ratio but should work OK.

I don't know, if this helps, but I'm using an 11 speed chain with a 10 speed front mech and 11 speed chain set. The front mech works perfectly.

Will your rear wheel take an 11-speed cassette? There are a lot out there that won't - including many of Shimano's own wheels.

Hey,

It will work sound,but tbh you should sell your 2xshifters and 2xderailleur's as one lot,you will sell these handy like this and you can leave your chain set as is for now,you will buy a 11speed 105 shifting kit for not much more than you sell what you have for,the though of looking at 2 x different shifters would drive me mental, what group-set you got ? I've done all these thing for the lads in the past but as I said, 2 x different shifters would not be the way I'd go,

Cheers zip,

Cheers Zip,
I have a sram red shifters 3yrs old with rival mecs <1yr old. I was thinking of putting these on the winter bike in place of a well used Sora. Would be thinking of a WiFli set up for 11sp.

I'm not up to date on the SRAM stuff as I'm a Di2 boy myself, if your going fitting them on your training bike I'd sell the SRAM red shifters and buy the new 11s apex shifters. There is still a lot of lads looking for 10speed stuff to work with 10speed wheels,

Front mechs don't really have any concept of 9/10/11 speed, since that number is controlled at the back.
The main factors influencing your front mechanism are the number of chainrings (double or triple) and the size difference between the chainrings.

10spd front will work fine with 11spd.

As others have said though you're kind of making life awkward for yourself. Front mechs aren't expensive in general. Replace everything but the chainset (cos they're expensive), and sell on the old stuff.

Keep an eye out and every year shops put up their older groupset stock at ridiculous discounts when the new groupsets are released.

Not true, new 11s front mechs have a much higher clamping point to allow for the altered cable pull in the new shifters.

So no, a 10s front mech will not work with 11s shifters.

However, if you keep your 10s LH shifter and 10s front mech, and use an 11s rear shifter and rear mech, and chain and cassette, then yes it will work, but it'll look w4nk.
