Seatpost weight sits high on the bike, which means every gram up there acts as a lever arm affecting how the bike responds to direction changes and accelerations. Ritchey's Superlogic Carbon 1-Bolt Seatpost keeps that lever light with a FlexLogic carbon layup that does double duty — saving grams while adding compliance. Ritchey combines multiple grades of carbon in the layup to add more bump-smoothing fore/aft flex without impacting lateral rigidity, and claims the result is 15% more vertically compliant than standard carbon layups. That's the headline feature here and what separates this generation from the previous Superlogic post.

The shaft itself isn't round inside. Force-directional butting puts more carbon material in the front and back of the shaft to deliver strength without unnecessary weight — you can feel that they are not round inside. FlexLogic builds on that foundation, tuning the layup to smooth vibration across rough tarmac, cobbles, gravel, and trail without sacrificing the strength-to-weight ratio Ritchey is known for. Construction is monocoque carbon fiber with a forged alloy clamp head, and the matte UD carbon finish on the latest version drops the previous red accents for a stealthier look.

Up top, the patented SideBinder clamp uses a single side-mounted bolt to handle both fore/aft and tilt adjustment at once. The wide cradle spreads load across the rails to reduce stress on lightweight carbon or alloy saddles, and infinite tilt adjustment lets you dial in saddle angle without the stepped detents some 1-bolt systems force on you. Choose between 5mm of setback for a more centered saddle position or 20mm of setback if you ride further behind the bottom bracket — the 20mm option replaces the older 24mm offset from the previous generation....
