—DESCRIPTION
Redshift's Switch Aero System allows you to have a proper aero position on the road bike you already own. The system is comprised of Quick-Release Aerobars and a Dual-Position Seatpost.
The Quick-Release Aerobars are different than any other aerobars on the market. The patented quick-release mechanism allows you to attach or remove the aerobars in a few seconds, without any tools. You can choose the best setup for every single ride.
The patented Dual-Position Seatpost lets you ride a true aero position on a standard road bike, without sacrificing your normal road position. And you can switch between road and aero positions on-the-fly while riding so you can always choose the best riding position for every part of your ride.
• Transform your current bike - switch from road to aero position on the bike you already own • No tools required - remove or attach the aerobars easily with the quick-release mechanism • Ride with ease - no more time and energy wasted switching from road bike to aero bike
Quick-Release Aerobar Details:
• Extensions are available in L-Bend or S-Bend • Massive adjustability lets you fine-tune your fit - extension length, armpad fore-aft, armpad width and height (Extension Riser Kit sold separately) • Secondary safety release mechanism prevents accidental release
Dual-Position Seatpost 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 • 16mm rearward setback (road position) • Check technical specifications for compatibility
What's in the Box:
• 1 x Dual-Position Seatpost • 1 x Quick-Release Aerobars (including Handlebar Clamps, Quick-Release Mechanisms, Aerobar Extensions, Armrest, Armrest Pads, and all required hardware

+FAQ
[Aerobars] Should I choose L-Bend or S-Bend extensions?
If you don't have any previous experience using aerobars, we typically recommend the L-Bend aerobars because they put your wrists and arms in a more comfortable, ergonomic position. This is usually a better fit for triathletes and long-distance riders. If you're planning on using the aerobars for shorter, higher-intensity efforts like a time-trial, then the S-Bend shape can give you slightly more leverage to put out maximal power.
[Aerobars] How do aerobars affect my bike fit?
This is a really important question, and it's one that we've spent a lot of time thinking about here at Redshift Sports, so get ready for a long answer! Aerobars (of any brand) work by rotating your upper body forward so that it is more parallel to the ground, and therefore less exposed to air resistance (imagine sticking your hand out a moving car window with your palm facing forward vs. with your fingers facing forward). If you don't change your saddle position when moving from road to aero positions, the angle between your thigh and your torso (otherwise known as the "hip angle") becomes tighter at the top of your pedal stroke, since your knees are effectively coming closer to your chest as you lower your upper body. For most riders, the tighter hip angle is uncomfortable and can actually reduce power output because you end up fighting against your body's own range of motion to move your leg over the top of the pedal stroke. It can cause back pain and generally leads to a riding position that is unsustainable, particularly for longer distance events. The other unintended consequence that occurs if the saddle position is not adjusted is that the aerobar armpads tend to be too far away to reach comfortably. You end up riding in a "superman" position with your arms extended too far forward, which puts a lot of stress on the supporting muscles of the arms, shoulders, and core. We specifically designed the Quick-Release Aerobars along with the Dual-Position Seatpost specifically to address this issue. The Dual-Position Seatpost addresses the fit implications of riding with aerobars on a road bike by allowing the saddle to move forward with the rider when shifting from road to aero riding positions. This forward movement effectively rotates the rider's body around the bottom bracket (where the pedals attach), naturally lowering the upper body down onto the aerobars without compressing the rider's hip angle. The forward movement also positions your body comfortably and efficiently over the aerobar armrest pads, letting you support your upper body through your skeleton, rather than relying on muscles. Together, the Quick-Release Aerobars and Dual-Position Seatpost provide an optimized aero riding position that allows you to ride efficiently, comfortably, and powerfully on your road bike in both road and aero positions.
[Aerobars] Will the aerobars fit non-round (aero-shaped) handlebars?
The handlebar clamps for the Quick-Release Aerobars need at least 22mm (7/8 inch) of straight, cylindrical handlebar on either side of the stem to clamp properly. Some aero-shaped handlebars have a sufficiently wide cylindrical section in the center of the handlebar to properly mount clip-on aerobars, however, some handlebars are ovalized or tapered within the clamping region. In this case, Redshift aerobars (or any clip-on aerobars) will not be compatible since they will not clamp securely on the non-round handlebar.The best way for you to check is to measure yourself, take it to a bike shop to get measured, or look up your handlebars specs online.

[Seatpost] 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:

[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.
[Seatpost] 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.
