The Fly is one of stiffest and most dependable performance tools in the SDG portfolio. The I-Fly uses SDG Patented Monorail Technology with nylon glass fibre, solid beam constructed base creating one of the lightest strength to weight saddles.

The I-Fly incorporates an EVA foam, minimalistically designed with a snag-less, flat-forward approach. Ideal for advanced cyclists with limited seated movements and those who prefer narrower, stiffer saddles. The Fly is for power and performance, catering to a wide spectrum of disciplines and available in dual panel designs.

About Performance Saddles

Performance saddles are narrower than the models designed for shorter ride comfort. They're intended for riders who have a committed riding style with weight on hands and feet so they're narrower and lighter. High tech padding materials and flexible body designs keep your pressure points comfortable and lightweight chassis components keep the weight down. Most have some kind of ergonomic design to reduce pressure on nerves and allow unrestriced blood flow to your sensitive areas. Womens models have a wider design to suit their naturally wider pelvis. Saddle widths vary across the ranges from narrow (upto 130mm), medium (upto 138mm) to wide (upto 146mm). Narrower saddles are the popular choice for longer distance riders as they do not cause the hips to be placed in an unnatural position. Wider saddles will often feel comfortable initially due to their greater surface area but then progressively decrease in comfort as the miles increase, the correct choice of saddle is a case of getting the balance between initial comfort and overall comfort.

About the SDG brand

Jerome’s first product was a seat made specifically for mountain bikers, replacing the delicate leather used by traditional European seat makers with a super-tough and light weight material known as “Kevlar”. Operating from a small factory in Southern California (a place they still call home), S.D.G. crafted unique, high-quality seats by hand, slowly carving out a niche among the mountain bike cognoscenti. During the mid 1990’s S.D.G. introduced some of the best-loved, lightest weight saddles, featuring super-light foams, and distinctively stitched covers. Many have become “classics”, and some, like the Bel Air, Satellite and Slim Jim, are still in production. By the end of the ‘90’s S.D.G. seats were standard equipment on most top-shelf mountain bikes.
