Description
Will this work?
- Single lever-side down-tube barrel adjuster, braze-on mount
- Chrome-plated steel construction
- Fits standard Shimano braze-on down-tube boss
- Compatible with all standard 4mm shift cable housing
- Period-correct for 1980s–90s road frames
Condition: Excellent. Chrome is clean, adjuster rotates smoothly, threads are perfect.
Notes from MyBikeThing: Original Shimano down-tube barrel adjuster — the lever-side unit for braze-on mounts. These are genuinely hard to source individually and show up on every vintage road restoration that needs inline cable adjustment. Chrome finish, correct fitment, ready to install.
Workshop Wisdom: Thread in with blue threadlocker on the mounting screw, torque to 3–4 Nm. Orient the barrel adjuster slightly outward so you can reach it mid-ride without looking down.
Guarantee: You put in the miles, we put in the work! 30-day Guarantee, rest assured of fit, function and condition. 🙂
