Roval Alpinist Seatpost

Mass is the enemy of performance, so we pulled out all the stops to make the Roval Alpinist Seatpost the lightest post we’ve ever seen that passes our standards. At 136 grams (27.2mm x 300mm), it’s about as light as you’ll find. Not only does light weight make for faster climbing, it also improves acceleration and ride quality. The Alpinist 2-bolt micro-adjust clamp with extended saddle cradle ensures precision fit and secure retention. Available in two sizes, 27.2mm x 300mm and 27.2mm x 360mm, each with a 12mm setback. And because they are backed by a no-fault crash replacement policy and lifetime warranty, you can rest easy knowing that we’ve got your back.

Very lightweight, quality seatpost. I'm

Very lightweight, quality seatpost. I'm very impressed with the fit and finish. The only reason I gave 4 stars instead of 5 is the clamp is a bit fiddly. If you don't have a full window in the middle of your saddle, it takes quite a while to set the saddle tilt. Also, don't ever-loosen the front bolt or you might lose the captured nut into the post... or worse into your frame if you don't run a Di2 battery.

Very light!

Been using this in a steel frame. It really doesn’t have any other considerable functional advantage over other specialized carbon seatposts, other than it’s very light! Would love to have a zero setback version Specialized! 😉

Great upgrade for my 09' Specialized Allez

I've been on a tear modernizing my old 2009 Specialized Allez. I've installed a few carbon fiber goodies to increase comfort and decrease weight. I purchased the Roval Alpinist seatpost during a sale after reviewing a few other CF seat posts with the main goal of bump conformance and decreasing weight. I felt the price point and features were there. So far, I've gotten one ride on the post, and it's shocking to see what the difference this post made! What were jarring bumps are now far more subdued. The only thing I'm having difficulty with is adjusting the seat. As you sit on the seat, the rear of the seat moves down, and the nose up due to the deflection of the post. It will take some adjustment to determine where the seat is level while sitting. I did not have trouble installing the post, but I was disappointed that CF grip gel was not included. Luckily, the bike shop had some on hand.

Design issue re: barrel nut

Use of a barrel nut inside the seat post to secure the saddle clamp is a poor design. There is no warning not to loosen the barrel nut excessively when fitting/adjusting the seat as it can fall into the bike frame.

Fantastic Seatpost

Superb lightweight seatpost with great fit and finish. Love that the setback isn't as far back as most and compatible with both steel and carbon rails. One thing to note, it's a bit trickier to fit a saddle without a cutout due to the top bolt. However, the top bolt has holes so you can use a very thin hex key to turn the bolt and I was able to get my old Aliante on.

Good seatpost for the cost

Super lightweight post - mine came in slightly under spec weight. Subtle branding. Affordable even compared to heavier carbon posts. The clamp isn’t ideal for constant readjustment, but if your bike fit is already dialed in, that’s not a problem. It would be great if it came in a zero setback option.

Simply amazing

Ride quality noticeably improved. Stupidly light and compatible with round and oval rails. Sleek and stealthy looks are just to die for
