Product Description: The patented Dual-Position Seatpost lets you ride a true aero position on a standard road bike, without sacrificing your normal road position. Along with the Quick-Release Aerobars it provides the benefits of a triathlon or time trial bike without the additional bike or price tag. The key to riding powerfully and comfortably is proper saddle position 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.

Benefits:

• Transform your current bike - switch from road to aero position on the bike you already own
• Ride with ease - no more time and energy wasted switching from road bike to aero bike

Details:

• Linkage design lets you switch between road and aero positions seamlessly while riding
• Choose the best position for every single climb, flat, or descent
• Maintain 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

Will my saddle bag fit with the Dual-Position Seatpost?

Most standard strap-based saddle bags will fit the dual-position seatpost without issue.
You may need to loosen the straps slightly to accommodate the movement that occurs between road and aero positions. If your saddle bag uses rigid clips, clamps, or some other inflexible attachment method, it's possible that your bag may not be compatible.
Here is an example bikepacking saddle bag from one of our ambassadors that works just fine with the Dual-Position Seatpost:

Is the Redshift Dual-Position Seatpost legal to use in a triathlon race?

Yes! The Dual-Position Seatpost is legal for use in any non-drafting triathlon. That includes all Ironman events, USAT sanctioned events, and the vast majority of triathlons worldwide. The only events where the seatpost is not permitted are draft-legal events, which are relatively uncommon. If you're wondering about a specific race, shoot us an email at support@redshiftsports.com and we'll help you figure it out.

Will the Dual-Position Seatpost fit a Shimano Di2 battery inside?

Yes, the standard "lipstick" style Shimano Di2 battery will fit inside the seatpost. Keep in mind that the inner diameter of the seatpost is ovalized, so standard round battery mounts may not be compatible. We have found that wrapping the battery with a thin layer of packing foam is usually sufficient to secure the battery within the seatpost.
