Breaking a 100-year-old tradition, the patented I-Beam Technology redefined the saddle-to-post connection by replacing the rails with a single beam that runs along the bottom of the saddle itself. In the late ‘90s, ideation stemmed from the demanding terrain of Whistler Mountain, British Columbia, Canada, where bike parts are put to the test and seldom pass. Bent, broken and popped saddle rails were the norm and SDG’s lead designer had the vision to create a saddle-to-post connection that featured a beam rather than rails and hence, the I-Beam Technology was born. Top racers from all disciplines quickly embraced the Technology and helped test the early prototypes. Early-adopting gravity bosses like Aaron Chase, Kyle Strait, Sam Hill, Eric Porter, John Kirkaldie and even XC top-guns like Geoff Kabush and Todd Wells were in the I-Beam Technology camp early on. Lisa Sher and April Lawyer weighed in as well. This direct, honest feedback from the globe’s most talented off-road bicycle racers translated into a better product, without question. Leading mechanics such as the legendary wrenchman Monkey and GT’s John Canepa, provided years of real-world race knowledge and insight.

Rated 5 out of 5 by Strong and stable Great saddle that does not move around, and the I Bean system means its easy to get adjusted perfectly. Narrow profile, and my back side is used to it, and so will your be if your looking for a saddle like this.. 06 September 2014
Rated 5 out of 5 by Very good saddle for long rides - light but comfortable. Saddle does have flex I have stuck to this saddle when changing bikes. It is very comfortable, and it starts to become more flexible after the first few months of riding. It has the added benefit that the Toppeak saddle bags attach easily and neatly with the "Quick Click" system. The single bolt attaching the saddle to the I beam post needs a fair amount of torque to keep it in position. 08 February 2014
Rated 4 out of 5 by The best I beam saddle so far The I beam Bel Air SL & post made an impressively light & cheap combi & was initially comfy, however, over distance vibration transmitted through the solid I beam made it uncomfortable. The Formula FX with it's cavity above the beam cures this without losing the initial I beam plus points. The quality also seems good & the incorporated bag mount clip is a welcome bonus. IMHO the best of the I beam saddles. 28 October 2013
Rated 4 out of 5 by comfy This saddle is comfy for longer rides and strong enough for DH,but has an annoying saddle bag holder clip thingy...when u take it off, the remainig part will make a raddling noise....a bit of glue will help :) 16 August 2013
Rated 5 out of 5 by This is a bargain! If you already have an I-Beam seat post / clamp, and want a comfortable, light weight road saddle, look no further. At £25 this is an absolute bargain. I bought mine to replace a Formula MT saddle (MTB) which, while comfortable for the first 2 hours, then starts to generate ache on the seat bones when road cycling (too padded).I weigh 78 kgs. It's worth looking at the I-Beam system, given that an alloy post / seat combo is as light - and cheaper - than many of its more glamorous competitors. 06 August 2013
