Mike As you'd expect from XTR it's a lovely bit of kit and appears to be very well made. Be aware though that if you're using this to go from 2 or 3x11 to 1x11 you'll need new chain ring bolts which aren't cheap although there some aftermarket alternatives.
Mr Ireland Easy to install and operated smoothly with new chain. Shipping fast, no problems. Only downside is this part wears out too fast - I only get 7 months on it so would recommend going to XT drive chain.
SCNZ Sweet chain ring - light and easy to assemble, and good pricing. It arrived quickly too.
