Shimano Ultegra 6700 10 Fach Kurbelgarnitur

Shimano Ultegra 6700 10-speed crank set in Shimano New Grey. The Ultegra crank has a hollow outer ring. The hollow outer ring is extra stiff, and also much lighter in comparison to a solid outer ring. The form has also been adjusted so even when your chain is cross chained maximally, the chance that it hits your outer ring is as small as possible. The hollow chain ring has a screw-thread at the back. The front stays clean, and there is a lesser chance of squeaking blade bolts.
