Shimano ULTEGRA FC-R8100 2x12 crankset on display

This article is a display item! Is a new item, was dismantled from a new bike because of a swap to electronic shifting!

The new FC-R8100 crank in the ULTEGRA range offers the same fast, precise front shifting performance and efficient power transmission for which SHIMANO is renowned. In addition, it is available in even more length variants than before. With a length between 160 and 175 mm, the ULTEGRA cranks are now also suitable for shorter riders, triathletes and anyone interested in shorter crank arms.

As a central component in SHIMANO's new 12-speed road bike line-up, the FC-R8100 crankset is characterised by SHIMANO's typical shifting quality and transmission efficiency. Redesigned for seamless 12-speed shifting, the ULTEGRA crankset is available in lengths from 160 to 175 mm. This means more power and improved customisation options for smaller riders, triathletes and riders with special biomechanical requirements.

Perfect balance between stiffness, stability, weight and rotational efficiency
