Despite the smaller and lighter frame, the DURA-ACE FD-R9250 offers our fastest chainring changes.
The fastest, and today it's even faster, thanks to DURA-ACE FD-R9250. Weighing less than 100 grams, the new model is 45% faster than Shimano's FD-R9150, which was already the fastest on the market. The frontal area of the FD-R9250 model has also been reduced to decrease aerodynamic drag.
