How Much Do Roval Rapide Stem Bolts Weigh? (M5×18 Titanium Swap)

Roval Rapide cockpit owners swap faceplate bolts and stem bolts routinely. But the most overlooked hardware is the M5×18 bolt-and-nut pair inside the bar clamp assembly — steel from the factory, titanium replacement at 7g per pair bolt-and-nut included.

Unlike stem faceplate bolts you can swap in 30 seconds, these clamp hardware are buried inside the cockpit assembly. You only get one shot per bar installation.

Step 1: Identify the Hardware

The Roval Rapide uses two M5×18 bolt-and-nut pairs — one per side of the integrated clamp. Not a standard hex-through bolt — it's a matched pair where both length and thread engagement matter. M5 diameter, 18mm length, nut included in the 7g measurement.

Step 2: When and How to Swap

1、Best done during bar installation — the bolts sit partially buried inside the clamp assembly

2、Remove one pair at a time to keep bar-to-stem alignment

3、Grade 5 Ti-6Al-4V, thin grease on threads to prevent galling against aluminum

4、Torque to Roval spec — clamp load identical to steel

Step 3: Complete the Cockpit

These are the last steel hardware on a Rapide cockpit after the faceplate swap. Carbon faceplate (3.7–5.9g), titanium M5×18 pairs (7g), titanium stem bolts — the entire front-end clamping system becomes composite or titanium. No alloy left anywhere you can see from the saddle.
