Sunrace have been knocking around for 35 years, and spent most of that time churning out cheaper transmission bits and bobs. In the last couple of years, though, they've been developing a high-end alternative, and the Driven RX groupset is the culmination of that work. The Shimano-compatible components include carbon shifters, chainset and mechs, and a 105g ten-speed cassette. The groupset is substantially cheaper than the comparable offerings from the bigger manufacturers, and the level of finish and attention to detail is very good. And the performance? well, we can't comment as yet but we're certainly hoping to get some bits on test in the next few months to see how they cope in the real world.
