Park Tool TWB-15 Pedal Wrench

A standard pedal wrench is great for quick adjustments, but the TWB-15 is designed for precision. By pairing it with a torque wrench, you can ensure your pedals are tightened exactly to the manufacturer's specification, which is critical for protecting lightweight carbon fiber crank arms from damage.

The TWB-15 features a standard 3/8" drive, making it compatible with almost any 3/8" drive torque wrench or standard drive handle you likely already have in your workshop.

While it is durable enough for regular maintenance, it is primarily designed for torque verification rather than heavy-duty removal of seized pedals. For extremely stuck pedals, a dedicated, long-handled pedal wrench is usually a better choice to provide the necessary leverage.

The 5mm thickness is specifically engineered to fit the standard 15mm wrench flats found on most bicycle pedals. It is thin enough to slide easily into tight spaces but robust enough to handle the torque required for proper installation.

It is designed to fit standard 15mm wrench flats, which covers the vast majority of bicycle pedals. However, if your pedals require a different size or use a hex-key fitting instead of wrench flats, this tool will not be compatible.
