The bifurcated horn of the seat creates a space for both male and female soft tissue areas while cycling in an aggressive, aero or drop position.

It features our signature full-cutout design. Hand shaped and covered with state of the art 1/4 inch Aerospace foam and individually, hand-crafted in genuine Italian leather*.

We now offer Vegan Leather for all our Infinity Seats. They have been tested for strength and durability. While at the same time it has the soft feel of elegant leather gloves. This has all been achieved through advanced technology without using exotic or domestic animal, or PVCs (polyvinyl chloride).

Carbon Fiber Rail is an oval rail, 7 x 10 mm, in a natural charcoal gray color.

Carbon Fiber Rails will make any of our seats 100 gms lighter.

Carbon Fiber Rails are interchangeable with any of our seats.

Carbon Fiber Rail Recommended for intermediate to advanced cyclists.

Carbon Fiber Rail Not recommended for any off road cycling, gravel biking, power assist bikes or extreme MTBing due to the nature of the carbon fiber material.

The Carbon Fiber rail diffuses the G-force shock felt from the surface of the road through the bike that transfers to the cyclist.

With Carbon Fiber Rail, while in a high performance mode, delivering a high wattage cadence, you’ll have a decrease loss of energy from side to side and an increase kinetic energy in a forward motion.

For side mount clamp of the Carbon Fiber Rail: you’ll need to get a 7x10mm ears and cups for your seatpost.

For top mount clamp of the Carbon Fiber Rail: should be fine, but you might need a longer bolt to accommodate the 3mm increase in height of the rail.

For Carbon Fiber Rail, watch video for installing G-Force pads for both side and top mounted seat posts.
