The 9-piece BitKit provides you with all the Torx® attachments you typically need for the repair and maintenance of your bike. The bits comply with common standards and fit all ratchets and torque wrenches from Topeak and most other manufacturers. However, they are 5 mm longer than standard bits, making it easier to reach recessed screws. The integrated knurling on the bits makes it easier to remove them from tools or holders.
