Shimano launched a voluntary inspection/replacement campaign on 21st Sept 2023 for some 11-Speed Bonded HOLLOWTECH II Road Crank sets.

A number of Specialized road bikes were fitted as standard with 11-speed Shimano Ultegra & Dura-Ace crank sets and may be affected (some models of Tarmac, Roubaix, Venge, Ruby, Amira, Aethos & Shiv).

Check your regional Shimano website to learn more - affected riders should stop riding immediately and schedule a free of charge inspection with an authorised Shimano service centre.
