Shimano designed this TL-FC23 Chainring Bolt Wrench Tool for both high torque and long reach capbilities when installing or removing chainring bolts. The T-handle style design carries 5mm and Torx T30 tools on the T-ends, and the long reach tool is also a T30. The chrome plated hardened steel maintains its precision tool faces throughout years of daily use, while the molded composite grip features excellent ergonomics for power application and torque with any of the three tool interfaces. It is a hand saver, for sure.

The oversized shaft provides incredible rigidity and torsion resistance, even on the long T30. This design works perfectly with the Hollowtech II cranksets, which feature the integrated crankaxle off the driveside crankarm/spider. Shimano uses a moderate strength dry torque compound out of the factory on these aluminum parts, and with a dearth of physical space due to the axle, and the need for some legitimate torque to "break" the bond, the tool length is surely appreciated.

Shimano's tools are popular with shop and pro mechanics because they are precise and durable. While the designs may appear different from many commonly sold tools, Shimano is concerned only with the requirements of the tool, and the mechanic who wields it, not appearances. The TL-FC23 Chainring Bolt Wrench Tool is a great tool for anyone who uses a T30 regularly and you get the benefit of the 5mm tool as well. Believe us, you'll use it, even looking for opportunities instead of burying it in your tool box.
