As there's lots of options to increase your bottom gearing via pan-sized cogs fitted behind your existing cassette I was wondering if I need a specific rear mech? At the moment I've a shorty X9 type 2 which, according to Spam, will only work up to 36T.
If I was going to use it with 40T expander, 10sp cassette and single chainring, is it just a case of a B-screw fettle or am I looking to break the bank with half a drivetrain replacement?
Cheers
Not sure on the cage length on mine but the Type 2 SRAM works up to 42 better than Shimano. Shimano needs something like the RAD cage to work properly up to 42t.
I have an X9 mech and one-up 42t expander working fine. As above I think its only Shimano need the rad cage sram are fine without.
Edit to add, what's the range on a shorty? That would be your only problem.
Whether you have a full-suspension bike (and the resulting chain growth) makes a big difference.
I have a shimano mech working fine with a 40t expander (Hope,fwiw) but mates have had to use a rad cage to get a 42t to work on near identical setups
Thanks for all the replies!
@Jon Taylor: It's going on a HT
@theotherjonv: just out of interest, what setup have you got?
Cheers
Slx long cage mech (and shifter fwiw) with a hope 40t extender cog on top of a SRAM 1050 cassette. SRAM chain, have had a race face nw and now an online ringmaster. All working fine!
