Reviews over the

SRAM X7 / X9 / GX Type 2 / Type 2.1 10-speed

To clean up the drivetrain on my Specialized Carve from late 2012, where certain gear combinations were starting to cause problems. Large chainring + cassette + chain + rollers, all original products, it's all good. Ultra-simple disassembly and reassembly, no nasty surprises, just the settings of the 2 derailleurs to adjust. Like new, all you have to do is ride.
