SDG Formula FX I-Beam Saddle

FeaturesReviewsAsk a questionDeliverySelect

This is the SDG Formula FX I-Beam Saddle. A superior and technologically advanced saddle for All Terrain use. Solid and versatile, this model continues to impress both the MTB and Road sets. After a two-year product development process, our designers crafted a slightly longer shell than many leading saddles, and as a result – the Formula series offers plenty of room to manoeuver in the cockpit. All of the Formula saddles rely on D2 Edge Flex to ward off discomfort on longer rides. In addition, the Edge Flex eliminates any sharp edges, so the legs won’t lose power and maintain smooth spinning motion. Its relatively flat profile features an ample rear section for all body types and its one-piece, embossed micro fibre cover is both durable and stylish alike.


This saddle uses I-Beam Technology – the original ‘Mono Rail’ seat to post connection system. This system leads to I-Beam Saddles having an unsurpassed weight to strength ratio with greater adjustability than most traditional saddle designs. This saddle has the Flex Cavity beam, a suspended I-Beam rail for added comfort and shock absorption on rides.
