This bolt is designed to securely attach a brake caliper to a bicycle frame, specifically where the frame has a 25 mm mounting surface.
The 'C' designation typically refers to a specific variant or part number within Shimano's product line, often indicating a particular length or design feature for a specific application.
No, this bolt is specifically designed for frames with a 25 mm caliper mounting width. Always check your frame's specifications before purchasing.
The bolt has a length of 38 mm.
While it is part of the BR-RS505 series, it is primarily designed for calipers intended for a 25 mm frame mount. Always confirm compatibility with your specific caliper model.
Typically, a standard hex wrench (Allen key) of the appropriate size is required for installation.
Tighten the bolt until it is snug and the caliper is held firmly in place. Avoid overtightening, which can strip threads or damage components. Consulting a torque wrench if available is recommended for precise tightening.
Verify that the frame has the correct 25 mm mounting specification and that the bolt is not cross-threaded. Ensure the frame's thread is clean and undamaged.
Check that the bolt is tightened to the manufacturer's recommended torque specification. Ensure the bolt is the correct length and type for your caliper and frame.
Ensure the bolt is fully seated and tightened, allowing for minor adjustments by slightly loosening the bolt, aligning the caliper, and re-tightening.
Setup: Ensure your bicycle frame has a 25 mm caliper mounting point. Align the brake caliper with the frame's mounting holes. Insert the 38 mm bolt through the caliper and into the frame. Tighten the bolt using an appropriate hex wrench until secure. Do not overtighten, as this can damage the frame or the bolt.
Compatibility: This bolt is specifically designed for frames with a 25 mm mounting surface. It is part of the Shimano BR-RS505 series and is intended for use with compatible Shimano brake calipers. Always verify compatibility with your specific bicycle model and brake system before installation.
Care: Clean the bolt and surrounding area periodically with a dry or slightly damp cloth. Avoid using abrasive cleaners. Periodically check the tightness of the bolt to ensure continued security, especially after rough rides.
