Thanks guys. Have been on Shimano for the last 4-5 years, but did like the feel of SRAM XO1 on a demo bike recently. Crisper and more “decisive” than Shimano. Big cost difference compared to Shimano so need to decide whether its worth the extra £140.
Mboy, to answer your question I did go through a spate of trashing rear mechs but have only done one in the last 4 years. Could be a combination of slightly better skilz and the shadow rear mech which is probably not quite so exposed as the old ones
If I go with XO1 SRAM mech the other issue that raises is whether to go 1×12 Eagle rather than 1×11. The Eagle cassette is £60 more than 1×11 but the cost difference between mechs, shifters and chains is negligible. Apart from the extra 50t cog, any big positives or negatives between the two? I had heard that the Eagle stuff wears slower and runs quieter?
