Just got mine through today [img]

Anyone installed one, any issues setting up shifting?
Just fitted mine, the XTR B-Tension screw needed dialled all the way in and the top two alloy sprockets were a really tight fit on the CK free hub which is a good thing as they'll be no movement under torque.
28 tooth front and 40 tooth rear gives me a 19" low gear so it should make the hills easier.
Very nice bit of kit, well machined and shifting is every bit as good as the XT 11-36 i removed, 14g lighter than XT so that will make all the difference 😉

What's the gear spread ratios on the cassette? Where did you get them from?
11-13-15-17-19-21-24-28-34-40 spread, bought from a mates shop [url= http://www.studiovelo.co.uk ]Studio Velo in Castle Douglas.[/url]
No but I intend to when my current cassette and TRex wear out.
Moving the closer ratios at the higher geared end makes sense to me. And a TRex being 50 quid is bonkers.
