Comfort and control

Lever hoods play an important role in road cycling comfort and safety.

Over time, original rubber compounds can deteriorate and become slippery or sticky. Replacing them immediately improves grip, ergonomics and lever feel.

Many cyclists use these replacement hoods to maintain older Shimano 105 and Ultegra groupsets that are still appreciated for their reliability and mechanical performance.
