Bottom bracket tap

Cyclus Tools bottom bracket tap: the essential tool for clean threading

When it comes to bike maintenance or restoration, precision is key. One area that’s often overlooked—but absolutely critical—is the bottom bracket shell. Whether you're restoring a vintage frame or installing a new crankset, having a reliable bottom bracket tap is essential. This is where Cyclus Tools, a trusted German brand in the world of bike tools, stands out for its durability and precision.

What is a bottom bracket tap ?

A bottom bracket tap is a specialized tool used to re-thread or clean the internal threads of the bottom bracket shell—the part of the bike frame that houses the bottom bracket. Over time, corrosion, wear, or improper installation can damage the threads. A tap allows you to restore the original threading or clean it up before installing a new threaded bottom bracket (BSA, Italian, etc.).

This step is crucial for a secure and precise assembly, ensuring long-lasting performance and safety on the bike.

Key features of the Cyclus Tools bottom bracket tap

Cyclus Tools offers several bottom bracket taps compatible with the most common thread standards:

• BSA (British Standard): 1.37" x 24 TPI – the most common on modern road and MTB frames.

• Italian (36 mm x 24 TPI): found on some classic Italian frames.

• Other standards available on request (e.g., BB30, PressFit – which may require different tools).

Technical specifications:

• Hardened high-grade steel for maximum durability.

• Precision-ground cutting edges for clean, accurate threads.
