Older Cervelo frames used rivets instead of threaded inserts to secure the front derailleur mount to the seat tube area. The Front Derailleur Mount Kit includes both the alloy mount and the stainless steel rivets needed to attach it, giving you everything required to replace a damaged or missing mount on S2, S3, and R-Series frames. Unlike the bolt-on mounts used on current Cervelo models, this rivet-style design requires permanent installation with a rivet gun, so plan on shop time or having the right tools if you're handling the job yourself. Most mechanics can knock this out quickly, but it's not a trailside repair.

The mount itself is machined from 6000 series aluminum with a black anodized finish that matches the original factory hardware. It provides the braze-on style interface that front derailleurs clamp to, positioning the cage at the correct height relative to the chainrings for accurate shifting across your gear range. Once riveted in place, the mount doesn't adjust or work loose over time, which is the point of using rivets rather than bolts on these frame designs. The trade-off is that replacement requires drilling out the old rivets and setting new ones, which takes more effort than simply unthreading a couple of bolts on newer frames.

Chain suck incidents, crash damage, and years of repeated derailleur adjustments can all compromise the original mount. Rivets can pull through carbon if subjected to enough force, and the aluminum mount can crack at the derailleur clamp surface. If your front shifting has become inconsistent and limit screw adjustments aren't solving the problem, inspect the mount for damage or looseness. This OEM kit restores the frame to working condition with components that match Cervelo's original specifications for proper derailleur alignment and long-term durability.
