SKU E2X Category

The Elite E2X is ideal for: Triathletes, Ultra Cyclists and Road Cyclists.

Ideal for cyclists who have a lean physique and “less cush in the tush”. Not recommended for upright cyclists such as Touring, Bike Packing or MTBers.

It allows for cyclists with perineum hot spots, cysts, or some type of surgical intervention. The rear flow vents allow the cyclist to slide back in the rear support of the seat while mastering their pedal stroke up the hills.

It features our signature cutout design with the lateral sling support. This allows the cyclist to rotate the pelvis forward to ride on the pubic rami.

The dimensions are 10.25 in (260.35 mm) by 6.5 in (165.1 mm). The inside sit bone to sit bone is 130 mm max. Weight: 265 grams.

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.

  1. Dalibor Mikulic

    I tried about a couple of seats before this one and couldn’t find a comfortable one. I was skeptical at first, but this saddle is everything it claims to be. I often ride for a couple of hours and enjoy cycling, this seat is great!

  2. Rich Wolf

    Did the World’s 12 hour TT championships. Training went well but my undercarriage was having issues.
    I have been intrigued by the Infinity saddle since I first saw it when I did the 24 hour TT in 2016.
    Made the decision to buy it the night before my race which was a leap of faith.
    Vince spent a bunch of time getting me fitted that night.
    It certainly made a huge comfort difference come race day. I exceeded my mileage goal and won my class (70 plus single speed).
    Thanks Vince for you time and saddle!
