Shimano 105 5800 Chainset
The pioneering four-arm design of the crankset, which was passed on to the 105 by Dura Ace and Ultegra, has now found its way into the road bike middle class. Excellent power transmission and the ideal balance between stiffness and low weight are thus now even higher than ever before. The uniform bolt circle makes it possible to realize all gear ratios with just one base crank; Chainrings are available with 34, 36, 39, 50, 52 and 53 teeth.
