microSHIFT Casete Advent X 10sp 11-48T acero/aluminio - negro

At first I had some troubles installing it. After a few unsuccessful tries where I would put and tighten the locking and still have lateral play I had no idea what I was doing wrong. I realised that my old hub spline was a bit scratched from the last cassette and I had to lube it. Then I could tighten it without problems and all cogs got into in position without play. Think about this, 10 speed is already lots of small plays at work and the lube allowed each cog to slide down all the way. The weight is killer. You need to buy the one with the number starting with G-104or as hier on the site "with Al. bracket ( spider )". The other one, H-104, is heavier! (but cheaper). So I am super happy with the purchase!
