New mech, shifter, cassette and chain.

scottthurlow

would you be able to link me to what stuff would work, I'm getting myself confused

The Rookie

An 11 speed cassette that is NOT a SRAM XD (so smallest cog an 11t).

Rear mech and shifter, just match the brand (SRAM or Shimano)

Any MTB 11 speed chain, but KMC are the preferred option.

Your ten speed crank and front mech will be fine but the mech may require re-indexing.

Why do you want to go 11 anyway?

scottthurlow

i want to get rid of the shifter, and i don't use both rings. and few friends have the 11 speed and i prefer it.

The Rookie

So you want to convert to 1x11, not what you asked!

In addition you will need a narrow wide chainring and suitable chainring bolts.

Why not just go 1x10 with a suitable cassette or expander, a lit less expence.

I've messaged you buddy, thanks

Agree with this - the conversion to 1*10 is a load cheaper in capital and running costs and you will be well impressed with the improvement to 1*10 anyway. I've done both and don't really see anything in the 1*11 that is notably different from the 1*10. You might want to consider a zee mech - was quite impressed with this because it is compact - but it is only 1*10 IIRC.

The Rookie

The only benefit of 1x11 over 1x10 really is that the ratios are slightly more closely stacked so you are less likely to fall between gears - that is unless you go XD driver or one of the new 'dinner plate' cassettes to widen the range on 1x11.

I rode for 2.5 years on 1x9 with just an 11-34, I've now converted to 1x10 with a Sunrace MX3 11:40, as I have rear suspension and am running a super short cage XTR mech I didn't want to push my luck with an 11:42, it copes with an 11:40 absolutely perfectly though.
