The 105's are 2013 vintage I believe, 10 speed.
Looking at going 1x10 possibly in the future with a Sunrace 11x 42...
Assuming I'm right that 9 speed XT mech uses same cable pull as 10 speed 105... Would I want a medium or long cage?
(Oh to check, 10 speed xt totally different cable pull to 105, right?? )
Yes
Thanks mate.
Am I right in thinking the same applies to a 9 spd Deore mech too (to cut costs alittle)
Thanks again.
Yeah. All 9-speed MTB mechs have the same cable pull. I've used XT and XTR with Ultegra shifters for years. I had 105/Deore on an earlier bike.
Thanks for confirming that for me.
Do you think I would get away with a medium cage for the 11-42 cassette?
42T is beyond the original design spec of any 9 speed Shimano mech. The quoted figures are usually conservative but I think that might be just too much. You may need something like a Goatlink
Do you think I would get away with a medium cage for the 11-42 cassette?
I'd say no or at least it won't be very satisfactory. The shifter / mech combo is fine though, that's what I'm using.
I use a 40t happily enough on a 9sp XT & 5700 shifter.
