Weight savings on a seatpost usually come with compromise, whether that's a spartan clamp, a low rider weight limit, or a saddle rail interface that fights you during setup. The Roval Alpinist Carbon Seatpost lands at 136 grams for the 27.2mm x 300mm version and pairs that with a 2-bolt micro-adjust clamp with extended saddle cradle , which is the interesting part. You get a genuinely light post without giving up the setup control most riders want when they're dialing in fit.

The 46mm saddle rail cradle enables an effective offset from 0mm to 20mm , so even though the post is only offered with a 12mm setback, you can slide the saddle within the clamp to cover most fit scenarios. That's worth knowing if you were hoping for a zero-setback version and don't see one listed. Slam the saddle all the way forward in the cradle and you're effectively riding a near-zero-offset post. Slide it back and you pick up additional setback beyond the 12mm baseline.

Compatibility covers both carbon and alloy rail saddles, and the system weight limit is 275lbs / 125kg . That rider capacity is worth calling out because a lot of ultralight posts drop the weight limit to hit their headline number, and this one doesn't. Roval backs the post with a no-fault crash replacement policy and lifetime warranty , which is the kind of coverage that makes a carbon post easier to commit to.... Read More
