FAQs
Is this a front or rear brake caliper?
This is a front brake caliper designed for the front wheel of a road bicycle.
What does 'Open Box Grade A' mean?
It means the product is new and unused, but the original packaging may be damaged, replaced, or opened. All accessories are included.
What type of brake shoes does it come with?
It comes complete with R50T5 brake shoes, which are designed for good performance on road rims.
How do I adjust the brake cable tension?
You can adjust cable tension using the barrel adjuster located on the brake lever or the caliper itself. For finer adjustments, loosen the cable anchor bolt at the caliper, reposition the cable, and re-tighten.
What is the 'drop' measurement?
The 49 mm drop refers to the distance from the center of the brake mounting bolt hole to the center of the brake pad mounting bolt. This measurement is important for frame compatibility.
Can I use this with carbon rims?
The R50T5 brake shoes are typically designed for alloy rims. For carbon rims, it is recommended to use brake pads specifically designed for carbon surfaces to ensure optimal performance and prevent damage.
Is installation difficult?
Installation requires basic bicycle maintenance knowledge. If you are not comfortable with bicycle mechanics, it is recommended to have a professional bike shop install it for you.
Troubleshooting
Brakes feel loose or spongy
Check and tighten the brake cable tension at the caliper. Ensure the quick release lever is fully closed. Inspect brake pads for wear and proper alignment.
Brake pads do not contact the rim properly
Adjust the brake pad position on the caliper arms to ensure they make even contact with the rim surface. Verify the caliper is correctly centered.
Wheel is difficult to remove or install
Ensure the quick release lever on the brake caliper is fully opened. Check that the brake pads are not rubbing excessively on the rim.
Brakes squeal during use
Clean the brake pads and rim surface. Try 'toeing-in' the brake pads slightly (angling the front of the pad closer to the rim than the rear) for smoother engagement.
