Product Information
Full details
The Tektro RL721 Top Mount Brake Levers are an ideal upgrade for road cyclists who want more control and comfort while riding on the tops of their drop handlebars. These levers provide a secondary braking position, making them perfect for commuters or long-distance riders who frequently change hand positions, though they are strictly for use with caliper or cantilever brake systems and will not function with V-brakes or mechanical disc brakes.

FAQs
Can I use these with V-brakes?
No, these levers are specifically designed for caliper and cantilever brakes and are not compatible with the pull ratio required for V-brakes.
Do I need to remove my handlebar tape to install these?
No, the hinged clamp design allows you to install these on the top of the handlebar without removing your existing bar tape.
Will these fit on handlebars that are not 31.8mm?
These levers are manufactured specifically for 31.8mm diameter handlebars and will not fit smaller standard sizes securely.
Are these the primary brakes for my bike?
No, they act as secondary 'interrupter' levers. You must have primary brake levers installed for full braking system functionality.
How heavy are the Tektro RL721 levers?
The pair weighs approximately 90-100 grams total.
Troubleshooting
Lever feels 'mushy' or has too much travel
Check your cable tension and ensure that the housing is fully seated into the lever and brake calipers.
Brakes feel weak when using the RL721
Verify that your primary brake calipers or cantilevers are properly adjusted, as these levers only pull existing cables; they do not amplify force.
Lever does not return to the start position
Check the return spring for obstructions and add a drop of bicycle-specific lubricant to the lever pivot.
Pros and Cons
Pros
- Provides a convenient secondary braking position
- Easy installation with a hinged clamp design
- Lightweight forged aluminum build
- Adjustable reach for custom fit
- Includes return spring for responsive feel
Cons
- Not compatible with V-brakes
- Designed only for 31.8mm handlebar diameters
- Requires existing drop bar brake system to function as a secondary control
Setup, Compatibility & Care
To install these levers, ensure your handlebars measure exactly 31.8mm at the mounting point. Because they use a hinged clamp, you can open the lever and place it directly onto the bar near the stem. Connect these in-line with your existing brake cable housing to ensure the pull ratio matches your caliper or cantilever brakes.
Maintenance: Regularly check the housing tension to prevent excess slack. Keep the pivot points lightly lubricated to maintain the performance of the return spring, and always verify that your main brake system is properly tuned as the RL721 relies on the main cables for tension.
