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.

The patented Dual-Position Seatpost lets you ride a true aero position on a standard road bike, without sacrificing your normal road position. You can choose the best setup for every single ride. The patented quick-release mechanism allows you to attach or remove the aerobars in a few seconds, without any tools. The Quick-Release Aerobars are different than any other aerobars on the market. The system is comprised of Quick-Release Aerobars and a Dual-Position Seatpost. Redshift's Switch Aero System allows you to have a proper aero position on the road bike you already own. Likewise, if you have a bike with an aero/oval/non-round seatpost, or if your bike has an integrated seatmast, the seatpost is also not compatible. Non-compatible posts: Unfortunately, if your bike's seatpost is smaller than 27.2mm (for example, the 25.4mm posts found on some recent model Cannondale Synapses) our seatpost is currently not compatible with your bike. Ask your local bike shop - they'll be able to accurately measure your bike's seatpost.

Feel free to shoot us an email at - we'll see if we can help out. If you know the make, model, and year of your bike, you may be able to look up the seatpost diameter online.You'll need to remove the seatpost from the bike frame (mark your existing seatpost height with a bit of tape before you remove it so you can replace it easily), and look for a number like 27.2, 30.9, or 31.6 (etc.). Most seatposts have the diameter printed somewhere near the bottom of the post.Not sure what size seatpost you have currently? There are a couple different ways to find out. Don't worry though, the shims are super-lightweight and essentially invisible once installed.

The ShockStop Seatpost is 27.2mm in diameter, so if your bike's seatpost is larger, you'll need a shim to adapt our seatpost to your bike's frame. Different bikes sometimes have different seatpost diameters.
