Dimension Tri Carbon Saddle

What Our Gearhead® Experts Are Saying:

"What stands out is how well the saddle holds you in place during maximum aero efforts. The carbon rails keep it stiff and responsive, and the extra foam up front genuinely improves comfort when you're deep in the extensions."

The Dimension Tri Carbon Saddle is engineered specifically for triathletes and time-trial riders who spend long periods in a forward, aerodynamic posture. Its compact 245x143mm design and V-shaped geometry position the rider closer to the front of the saddle, reducing unnecessary movement and improving power transfer during sustained aero efforts. The seat area is advanced by 2cm to better support aggressive positioning, while a widened tip ensures stability when resting heavily on the front of the saddle.

A redesigned PAS channel enhances ventilation and relieves pressure in the genital-prostatic region, improving comfort and blood flow during extended periods in the extensions. Variable-density foams—15% thicker in the upper and nose—create a wider, more supportive contact area that distributes pressure evenly when riding at maximum intensity.

The carbon-focused construction sets the performance tone. Nack rails use a composite of carbon fiber, Kevlar, and aluminum filaments to deliver exceptional stiffness-to-weight efficiency, while the long-fiber carbon base enhances responsiveness under load. Together, they create a lightweight, stable platform that remains supportive through high-torque efforts and aerodynamic positioning. Designed through on-track testing and refined in the wind tunnel, the Dimension Tri Carbon Saddle brings efficiency, comfort, and precision to competitive triathlon and time-trial setups.
