Ritchey’s superlight carbon SuperLogic 1-Bolt seatpost gets a simple facelift on the outside and a smart layup inside, boosting comfort without gaining weight. Plus, there are two new lower-offset options to better fit modern road bike fits. It even gets a >10% lower price than before. But this is a top-tier lightweight carbon post, so we still can’t quite call it affordable.

One of the lightest mainstream seatposts out there, from a claimed 148g (27.2 x 350mm) is now more comfortable. And comes with two new low-offset setback options. Plus, it also gets the latest low-key Ritchey relabeling concept. Gone are the earlier little red accents, now simply gloss black over carbon for a stealthy look to the latest versions of their top-tier SuperLogic components.

What all is new?

Now with a FlexLogic carbon layup, Ritchey says their top lightweight SuperLogic 1-Bolt seatpost is better than ever, offering “15% more vertically compliant than other carbon layups“.

We first experienced FlexLogic more than a dozen years ago when Ritchey introduced it on the MTB line. Originally developed with their XC racing teams back then, Ritchey combines multiple grades of carbon in the layup to add more bump-smoothing fore/aft flex without impacting lateral rigidity. These SuperLogic posts already featured “force-directional butting” with more carbon material in the front & back of the shaft to deliver strength without unnecessary weight. (You can feel that they are not round inside.) Now, that’s where they’ve refined a FlexLogic layup to help smooth vibrations over everything from rough tarmac to cobbles, and from gravel tracks to trails.

As for setback, the new posts also shift from the old 24mm offset, and now you pick between 5mm back or 20mm offset.

Riding with SuperLogic posts & their 1-bolt heads

The Ritchey SuperLogic 1-Bolt seatpost has long been one of the lightest and longest-enduring carbon posts on the market. We’ve been riding them for more than a decade and a half.

My own Festka One Gravel bike has had a SuperLogic Link post in it for 8 1/2 years without any issue. It’s really light, as was already surprisingly comfortable. That’s why – even though I’ve since cycled through several different saddles, many sets of wheels, two groupsets, and ultimately the recent 1-piece SuperLogic Butano bar – the original SuperLogic post is still there today. Set it and forget it. I’m only now considering if I should try out this new one to see if it is even more comfortable.

The 1-bolt head is also used by other companies for their proprietary aero posts, like the one on the new 3T RaceMax² Italia gravel bike that I recently tested.

What’s that seatpost with the integrated light?

From the paragraph under the photo you are referring to, it says “The 1-bolt head is also used by other companies for their proprietary aero posts, like the one on the new 3T RaceMax² Italia gravel bike that I recently tested.” so the post with the integrated light is the 3T model.

It’s a proprietary 3T seatpost (using Ritchey clamp) sold with their Racemax2 Italia.

How easy is it to fit a saddle to this seatpost? Also, how precisely can you adjust the saddle angle and does it stay at that angle forever?

My Wilier has a bespoke seatpost made by Ritchey with this clamp design. I’ve never had any problems installing saddles to it. The adjustment is infinite, just mild taps to find tune. And I’ve never had it slip, even when I had my saddle slammed forward on the 20mm setback post (I later changed to the 5mm, which has the same clamp).

Ritchey component fan weighing in.

I have an old WCS carbon (with setback and 31.6mm dia.) with a similar one-bolt design that was really tricky to set up, as all the bits kept separating (including a plastic bit that kept all the fiddly parts together). It slipped once even though torqued correctly, but I slam the saddle all the way back, so this was probably a reason for this. Since then, carbon paste and slightly ‘less slam’ has made sure that there’s been no slip ever since. WOuld I buy one again? Sure, just wish that they’d make one with a 25mm set back, or 30mm. Cheers.

This article popped up on my feed at the right time. About to build a new bike up and the seatpost looks great. But also glad to find out their stem is compatible with FSA ACR headset. Think i’m going for a full Ritchey cockpit with their Venturemax handlebar too.
