After about 8 hours ride time on my set up, no dropped chains and I am using a normal Chromag 32 and MRP XC guide. Shifting is a much lighter feel that SRAM used to have and I like that. I do miss the double release that XTR has and XTR shifts a fair bit faster particularly the release shift to a higher gear I think partly because Shimano releases when the click happens as opposed to SRAM where you have to let do of the shift paddle. I kept fiddling with cable tension but that is just how it works.
The SRAM chain is coated with goo too that loves to collect dirt. Pulley wheels were gunked up fast. But that's easily corrected with a bit of citrus degreaser. Shimano road chains have this goo too but not the latest off road chains. At least mine are like this.
The 32 is not low enough for me though and a XX1 crank and 30 are on order. I would rather keep the Shimano crank but that 30 tooth Race Face still hasn't showed up and I may want a 28 too so that is how we go.
Debate? Bikes are made for riding not pushing.
