A practical choice for home mechanics and workshop users servicing compatible 7–12-speed cassettes with 11–26-tooth sprockets.
The BTL-122 T-RexGrip is a cassette plier-style freewheel turner designed to hold the sprocket securely while you carry out cassette removal or servicing. Open the jaws, position them on the sprocket and let the spring mechanism lock them in place, helping prevent slipping as you work.
Compatible with 7–12-speed systems and sprockets from 11–26 teeth, it covers a broad range of common road, gravel, mountain bike, touring and urban cassette setups. The substantial handle gives you useful leverage, while the Kraton handle provides a comfortable, firm grip.
At just 80 g, the T-RexGrip is easy to handle and convenient to keep in a home workshop or take to a servicing area. Choose it if you want a straightforward alternative to conventional sprocket-holding tools, with one-size construction and a spring-assisted grip that keeps the cassette firmly in position.
