The new hard ace 9100 is here and the new SHIMANO DURA ACE R9100 C40 wheels is part of this new generation. This model is the most versatile in the range for the intermediate height of its circle. The C40 set can be used both in the mountains and on the road thanks to the braking aluminum surface. Contrary to what the name can suggest, these wheels are 35 high and not 40 mm. The circle is instantly recognizable thanks to its clean look and the famous silver character. Shimano cone/sphere bearings require regular maintenance but last much longer than industrial bearings. Thanks to the circle of intermediate height, the rays can also be shorter in this way are more flexible and optimize the transfer of power. The Shimano wheels guarantee excellent voltage of the rays and a high side rigidity.
