TOOPRE TL-341 Crank Bolt Removal Tool Kit, Controlled-Leverage 8mm and 10mm Hex Tool with Storage Case

TOOPRE TL-341 Crank Bolt Removal Tool Kit, Controlled-Leverage 8mm and 10mm Hex Tool with Storage Case

Loosen compatible bicycle crank bolts with the TOOPRE TL-341 controlled-leverage removal kit. A bearing-supported handwheel, two M10 threaded rods, 8mm hex keys and an 8-to-10mm adapter provide a supported approach to crank service. Supplied as a complete black kit in a fitted carrying case.

Product highlights

• Controlled leverage: the threaded rod and bearing-supported handwheel apply gradual force through the lever arm to loosen a compatible crank bolt.
• 8mm and 10mm hex applications: includes short and long 8mm keys plus an 8-to-10mm adapter.
• Two rod lengths: M10 x 200mm and M10 x 270mm rods accommodate different crank layouts when the tool can be correctly supported.
• Aluminum components, stainless steel rods and Cr-V hex keys combine in an organized kit with a hook and pedal support axle.
• Fitted carrying case keeps the components together. Check crank-bolt access, thread fit and tool clearance before use; not every crank design is compatible.

A supported approach to crank-bolt removal

The TL-341 uses a handwheel and threaded rod to move a lever arm gradually. The hook bears against a secure support at the pedal end of the crank, while the hex key engages the crank bolt. This arrangement gives the mechanic a controlled way to apply loosening force.

Useful size options in one kit

Use the short 8mm hex key with the lever arm for initial loosening, then the long key to complete removal. The supplied adapter expands the kit to matching 10mm hex bolts. Choose the 200mm or 270mm rod according to the required reach and available clearance.

Set up before applying force

Verify the crank and pedal-support thread match, fit the support axle where appropriate, and seat the hook securely. Insert the correct hex key fully into the bolt. Turn the handwheel steadily while keeping the assembly aligned. Once loose, remove the leverage tool and finish with the hex key. Stop if any component slips or cannot seat properly.

Storage and supplied equipment

The kit includes the handwheel, hook and support parts, lever arm, pedal support axle, two threaded rods, two 8mm hex keys, 8-to-10mm adapter and fitted case. Approximate kit weight including the case is 1723g. Bicycle and crankset are not included.
