I'm with BaGearA on this one. It's getting ridiculous 50T at the rear. Something new to sell to us upgrade obsessed cyclists. If you think you need a 50T at the back stick too a 2-10/11 setup, far cheaper in the long run save the cash for a worthwhile upgrade and if you're buying it because it looks the ducks nuts "which it does" then hey enjoy. Here's getting to top before you. ???? (11-40 / 34T)
