Redshift Dual-Position Seatpost

They Say... The patent-pending Dual-Position Seatpost lets you ride a true aero position on a standard road bike, without sacrificing your normal road position. The key to riding powerfully and comfortably with aerobars is proper saddle position. The forward position of the dual-position seatpost allows you to ride with proper aero bike fit on a standard road bike, letting you ride faster and more comfortably. And since you can switch between road and aero positions on-the-fly while riding, you can always choose the best riding position for every part of your ride. Dual-Position Seatpost Features: Linkage design lets you switch between road and aero positions seamlessly on-the-fly while riding. Choose the best position for every single climb, flat, or descent. Linkage design maintains proper leg extension in both road and aero positions. Saddle moves forward 50mm, corresponding to approximately 4 degrees of effective seat tube angle change. Aero road riding position optimized for proper handling on a road bike. Simple, durable two-bolt saddle clamp allows infinite saddle tilt adjustment and reliable clamping. 16mm rearward setback (road position). Legal for use in all Ironman and USAT Non-Drafting Triathlons (the vast majority of amateur triathlons worldwide).
