You might be upgrading or building a bike from scratch but the road bike groupset that you choose can have a big influence on the ride that you experience. There is a wide choice of electronic and mechanical bike groupsets available. Electronic groupsets like SRAM eTAp, Shimano Di2 and Campagnolo EPS offer super smooth and instant gear changing as used by pro cyclists all over the world. Mechanical systems are more affordable with weight being the big difference between them and their performance.
