Switch Aero System
Couldn't load pickup availability
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.
Benefits:
• 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:

We offer two different shapes of aerobar extensions: L-Bends and S-Bends. The L-Bends (or ski-bends) tend to place your wrists in a more ergonomic, comfortable position that's great for long rides and triathlons. The S-Bends let you pull against the extensions effectively for intense time-trial efforts. Not sure which one is best for you? We generally recommend the L-Bend extensions if you're on the fence.
Different bikes sometimes have different seatpost diameters. 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. Don't worry though, the shims are super-lightweight and essentially invisible once installed.
Not sure what size seatpost you have currently? There are a couple different ways to find out.
• Most seatposts have the diameter printed somewhere near the bottom of the post. 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.). That is the diameter of the post.• If you know the make, model, and year of your bike, you may be able to look up the seatpost diameter online. Feel free to shoot us an email at info@redshiftsports.com - we'll see if we can help out.
• Ask your local bike shop - they'll be able to accurately measure your bike's seatpost.
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. 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.

Bought this post because of the AWFUL Chicago streets, and I am overjoyed at it's performance. I love that it is adjustable, feels extremely well-made, and enhances the look of my e-bike. Thank you for such a thoughtful product, my butt especially thanks you. Money well spent!

This is a great addition to my gravel bike. It took a few adjustments to get the right elastomers but, it definitely smooths out the ride. Will be purchasing a set for my road bike.

Love the stem!! It really takes out all the worse bumps from your ride, and on rough trails really did offer a smooth comfortable ride.

I hesitated buying this stem wondering would it work, was it a waste of money but I’ve had three off road rides with my new stem and I love it. I usually get pins and needles in my hands after riding for a while but that’s gone now. Added to the comfort is the improved handling on bumpy tracks and roads. I can ride a corrugated road now without feeling like I will get shaken off the bike. Very happy.

I love my Redshift post! I recently had a lumbar contusion and the post has smoothed and cushioned the roads and trails. I’m able to stay on the bike while healing.

After much thought I bought a red shift suspension stem and initial thoughts are that it's good, think they will become standard across all my gravel bikes.

I just finished my first ride with the Resdhift Shockstop Suspension Stem and I noticed the difference immediately. Having ridden for many years with rigid front ends (I’m 64) I now wish I had discovered this earlier in my life. The chatter that it removes from my wrists, arms and shoulders is easily noticed. This experience has been so good that now I’m considering the seatpost Redshift offers as well. The interesting thing for me is that I’ve promoted and sold these products for years based upon input from others. I just didn’t think I needed one myself. Get yourself one! You’ll never go back.

The shock absorber was easy to install and works as described cuts down on the impact. I recommend it if you're going to do gravel, writing and bumpy bumpy roads

Wow, once I got the fit dialed on this seat post I thoroughly understood why everyone was upgrading their set ups with these products. Riding a long distances is what I do for fun and for a living and this seatpost made all the difference in the world. Pay attention to the recommended Sag settings as its key to finding comfort and keeping a proper pedaling extension. 10 out of 10 would recommend.

United KingdomGamechanger set-up for triathlon
I fall into the category of a user with a decent road bike but didn't want to throw down more money on a triathlon-specific bike (nor did I have the space for another bike). The switch aero system solved my conundrum by giving me the option for an optimised road or triathlon position in a heartbeat. Plus, the quick-release aero bars are genius, and whilst you can buy cheaper / lighter ones, the time saved by not having to remove the whole set-up every time is game-changing. I particularly love this when I have removed my aero bars for a club road ride, but I want to put them back on quickly when I jump on my turbo for Zwift. I'll be adding an 80mm shockstop stem to my set-up to finish off my upgrades to smooth out the terrible UK roads when on the aero bars. Well done Redshift! Innovation at its finest.
United StatesQR Aerobars
These aerobars are great! I'm impressed with the engineering and how solid they feel when using them. The quick on and off will be good for switching back and forth between group and solo rides.
CanadaMore than just for aero gains
I have had this seat post for several months. I have found that moving the saddle forward and up is not only good for aero gains but also great for climbing steep grades as it keeps you more overtop of the bottom bracket. I also find having an occasional change in position great for long endurance rides.
United Statesquick release aero bars on cannondale T1 touring bike
excellent. I also purchased the 30mm risers you offer. I have a redshift 30% 80mm stem and the combination is very comfortable and allows use of the aero bars as an alternative rest position on flats and downhills to relieve stress on the hands and shoulders. This was purchased for touring and longer endurance rides. I moved my seat forward and I don't find the position shift to the aero bars uncomfortable. The top shelf handlebar might further enhance the comfort.
