Cassette Wrench

A modern and effective replacement for the traditional chain whip, our 1670/2BI Cassette Wrench gives you a quick and easy way to securely hold a cassette to loosen a lock ring.

Each side of the tool has 3 pins that mesh with the cassette teeth to hold the cassette in place. The pins have anti-slip ridges at the outer edges to keep the tool in place and keep your knuckles from bleeding.

We make two versions: one to fit cassettes that have either an 11 or 12 tooth small cog, and one to fit cassettes with a 13 or 14 tooth small cog such as "junior cassettes". The 11/12t version features longer pins on the 12t side designed to reach past the 10t cog found on some SRAM and Shimano mountain bike cassettes.

Once you give our Cassette Wrench a try we're pretty sure you'll never want to go back to at traditional chain whip again.

We make this tool in our European factories from the highest quality tool steel, hardened and tempered then chrome plated in accordance with EN12540 for a long service life.

The handle is 350mm in length for excellent leverage to grip your bike cassette securely and with minimal effort - this bike tool is solid, thick and will not buckle under pressure allowing you total confidence in it's performance


  • Material: special tool steel, hardened and tempered 
  • Surface finish: chrome plated according to ISO 1456:2009 
  • Ergonomic heavy duty double component handle 
  • The freewheel remover is intended for all types of sprocket including cassete types. It is useful  for freewheel with 11 and 12 teeth.

Great experience with Paul. Had an issue with my Fox X2, and sorted me with one of his EXT shocks in the time while a new part came from the UK. Really transparent service, explaining in details the issues and solutions. Chur!

"Proflow have been super important for me with bike setup. They're very professional and I love the fact they think outside the box to get the most out of suspension. I definitely couldn't have got my bike feeling the way it does without their help!"
