Description
Small molded parts that clip into frame ports don't last forever. Every time you pull a brake hose for service or swap handlebars, the Brake Cable Stop from Cervelo takes stress at its retention tabs and sealing surfaces. This hydraulic version fits the oval slot on Cervelo's top tube and guides the brake hose into the frame while keeping water and debris out of the internal cavity. When the original gets cracked, loose, or goes missing during a rebuild, this OEM replacement restores the tight fit and clean appearance the frame was designed around.
The tool-free design uses a small molded lever that lets you pop the stop in and out without reaching for hex keys. That's convenient during initial assembly and makes future service faster, but the trade-off is that the plastic retention features wear with repeated use. The quality molding process Cervelo uses creates a precise fit against the frame opening, and a fresh stop sits flush with no gaps or rattles. If your current stop has started to feel loose or doesn't quite seal against the frame surface anymore, it's doing less to protect the internal routing than it should.
This hydraulic version is sized specifically for brake hose diameter and won't work properly with mechanical brake housing, which requires the CBS-TTC-TT-MECH variant instead. Make sure you're ordering the correct version for your brake system. The stop fits R-Series rim brake frames from 2014-2019, S3 rim brake frames from the same period, the Rca and R5CA, and P2/P3 frames from 2014 onward. Sold individually, so check how many cable entry points your frame uses before ordering.
