1. Introdução
Thank you for choosing the SRAM TT 500 Reverse Brake Lever Set. These high-quality aluminum brake levers are designed for time trial and triathlon cycling, offering reliable stopping power and an aerodynamic profile. This manual provides essential information for the proper installation, operation, and maintenance of your new brake levers to ensure optimal performance and safety.
The SRAM TT 500 levers feature an anodized aluminum construction, ergonomically designed reverse levers with integrated return springs, and internal cable routing for a clean setup. They are compatible with handlebars having an internal diameter greater than 19mm and work with both caliper and cantilever braking systems.
2. Informações de segurança
Always prioritize safety when installing and using bicycle components. Improper installation or maintenance can lead to serious injury or death. If you are unsure about any part of the installation or adjustment process, consult a qualified bicycle mechanic.
- Ensure all bolts are tightened to the manufacturer's specified torque settings.
- Regularly inspect brake cables and housing for wear or damage. Replace components as necessary.
- Test brake function thoroughly before riding.
- Ao andar de bicicleta, use equipamento de segurança adequado, incluindo capacete.
- Não modifique as alavancas de freio nem quaisquer componentes associados.
3. Configuração e instalação
This section outlines the steps for installing your SRAM TT 500 Reverse Brake Levers. A 5mm Allen key is required for installation.
3.1 Desembalagem e Inspeção
Carefully remove the brake levers from their packaging. Inspect both levers for any signs of damage that may have occurred during shipping. Ensure all components are present.
3.2 Handlebar Compatibility
The SRAM TT 500 levers are designed for handlebars with an internal diameter greater than 19mm. Verify your handlebars meet this requirement before proceeding with installation.
3.3 Lever Installation into Handlebars
- Prepare the Lever: Before inserting the lever, ensure the internal expansion mechanism is sufficiently loose. Use a 5mm Allen key to slightly loosen the internal bolt if necessary.
- Insert into Handlebar: Carefully slide the brake lever into the end of your handlebar. Ensure it is fully seated and oriented correctly.
- Tighten the Lever: Once the lever is in position, use the 5mm Allen key to tighten the internal bolt. This expands the mechanism, securing the lever firmly within the handlebar. Tighten until the lever is secure and does not twist. Note: Some users find it helpful to remove the pivot nut/bolt from the brake lever blade to access the internal bolt more easily, then reattach it after tightening. If doing so, note the spring orientation.
- Repeat for Second Lever: Follow the same steps for the other brake lever.

3.4 Internal Cable Routing
The SRAM TT 500 levers feature internal cable routing for a clean and aerodynamic setup. This requires careful threading of the brake cable housing through the handlebars and then through the lever body.
- Thread Cable Housing: Route the brake cable housing through your handlebars to the lever's entry point.
- Insert Inner Cable: Feed the inner brake cable through the lever body and housing. Ensure it moves freely without kinks or excessive friction.
- Connect to Caliper: Connect the inner brake cable to your caliper or cantilever brake system according to the brake manufacturer's instructions.
- Ajuste a tensão do cabo: Adjust the cable tension to achieve the desired brake feel and lever travel. Ensure there is no slack and the brakes engage firmly.
3.5 Final Adjustments and Testing
- Ensure both brake levers are securely fastened and do not rotate or move within the handlebars.
- Check that the brake cables are properly routed and secured, and that the brake calipers engage and release smoothly.
- Test the brakes at a slow speed in a safe area before riding at higher speeds or in traffic.
4. Instruções de operação
The SRAM TT 500 Reverse Brake Levers are designed for intuitive and responsive braking control, particularly in aerodynamic riding positions.
- Frenagem: To engage the brakes, firmly squeeze the lever towards the handlebar. The amount of braking force is proportional to the pressure applied to the lever.
- Ergonomia: The ergonomic design and integrated return springs provide a comfortable grip and quick lever return, allowing for precise modulation of braking power.
- Controlar: Practice braking in a safe environment to become familiar with the feel and response of your new levers.
5. Manutenção
Regular maintenance ensures the longevity and safe operation of your SRAM TT 500 brake levers.
- Limpeza: Clean the levers regularly with a damp cloth and mild soap. Avoid harsh chemicals that could damage the finish.
- Inspeção de cabos: Periodically inspect brake cables and housing for fraying, corrosion, or damage. Replace them if any wear is observed to maintain optimal braking performance.
- Aperto do parafuso: Check the tightness of the internal handlebar clamp bolts and the lever pivot bolts periodically. If pivot bolts become loose, apply a small amount of blue threadlocker (e.g., Loctite 242) before re-tightening to prevent future loosening.
- Lubrificação: Ensure brake cable inner wires are lightly lubricated where they pass through housing and pivot points for smooth operation.
6. Solução De Problemas
| Problema | Possível causa | Solução |
|---|---|---|
| Lever feels loose in handlebar | Internal expansion bolt not tight enough. | Re-tighten the internal 5mm Allen bolt. Ensure the handlebar's internal diameter is compatible. If still loose, consider using a thin shim (e.g., electrical tape) around the expansion mechanism before re-inserting and tightening. |
| Poor braking performance / Spongy feel | Incorrect cable tension, worn brake pads, damaged cable/housing, or caliper issues. | Adjust cable tension. Inspect and replace brake pads if worn. Check cable and housing for damage and replace if necessary. Ensure brake calipers are properly aligned and functioning. |
| Lever pivot bolts loosen over time | Vibration during riding. | Remove the pivot bolt, apply a small amount of blue threadlocker (e.g., Loctite 242) to the threads, and re-tighten. |
| Cable does not move smoothly | Kinked cable housing, dirty/corroded cable, or insufficient lubrication. | Inspect cable housing for kinks and replace if damaged. Clean and lubricate the inner cable, or replace if corroded. |
