The Redshift Dual-Position seatpost is a modernized execution of this concept of shifting the seat position and it does it extremely well. Additonally, while going downhill, the more laid back road bike position biases weight toward the rear of the bike providing more control versus the front-heavy triathlon angle which can make for more tentative descending. It also positions your upper body weight more evenly over the aerobars so you are using your skeletal system instead of your muscles to keep upright. The more forward positon also opens up your hip angle letting you ride more comfortably while bent over the aero bars. The aero position forces more focus on the glutes and hamstring. So what exactly is the benefit of shifting the seat? On a road bike, with slacker seat angle, you can climb using a balance of your leg and glute muscles. This is not a new idea during the heyday of triathlon technology in the late '80's/early '90's, there was a product called the "Seat Shifter" popularized by pros like Mike Pigg which allowed triathletes to scoot the seat back and forth via a cable. The Ritchey seatpost I use offers only 25MM of offset so it really doesn't get you in to the steep tri position.

In fact, it gives you a full 50MM of fore/aft difference.This means that if your road bike seat tube angle is 73 degrees, you'll be able to achieve 77 degrees in the forward position (tri bikes typically offer 76 to 80 degrees). The seat post actually allows you to switch position on the fly, while riding. Turns out my first impressions would change dramatically. Further, I assumed that the 400 gram seat post would be excessively heavy and I assumed that you'd have to reinstall the saddle for forward or backward-biased postion, so I immediatly discounted it. With respect to the seatpost, in fact, on my Cervelo R3, I use a Ritchey Superlogic seatpost that I flop between rear-biased road riding and forward-biased triathlon riding so I didn't think the seatpost would be that that much of a revelation. Plus, being able to easily remove aerobars is very convenient for putting a bike in the trunk of a car aerobars can make the bike unweildly and awkward to fit. The idea of quick release aerobars is even more appealing because I like the idea of reducing weight when riding "road style" without aerobars but like the flexibility of adding them easily. I was initially more interested in the concept of quick-release aerobars than a reversible seatpost because aerobars are the biggest aerodynamic advantage you can add. Their products are designed to make it easy to convert a road bike to triathlon use with easy-to-remove aerobars and a dual-position seatpost that allows the rider to get into the more forward "tri position" easily. The Kickstarter response was impressive they sought to raise $20,000 but ended up with nearly $50,000. They had some cool ideas and leveraged Kickstarter to fund the Switch Aero System. Redshift was founded in 2013 by a bunch of mechanical engineers applying their passion to cycling components. For more information and to buy, visit Redshift Sports.
