Would be great if someone can comment. I recently receive end caps from Reynolds to convert my 10x135mm QR to 12x142mm for the rear 29er Carbon wheels. The problem is the end cap on the cassette side will not fit. The diameter of flange of 12x142mm is too big and will not fit into the cassette body. The rear cassette is 10 speed SRAM XX (X glide) from 2011. Anybody run into this problem?
