RailGun GT mold development
The pioneers of high-performance, low seat-angle seats on short wheelbase recumbents brought our famous carbon-fiber seat and tailbox to a new performance and usability level. We are seeing about a two mph increase in speed over the original RailGun at 30mph.
The GT is intended for ultra distance events and speed-touring. It has around eight degrees of recline. When used properly, this seat should do away with the need for "bridging" when at high power as it more properly positions and supports your body by supporting the spine and pelvis so the the sacrum floats slightly off of the seatpan when under power to prevent hamstring irritation and damage often seen on other carbon seats. It doesn't flex in the middle of the seat as all other seats do, for much quicker acceleration, faster/easier climbing and better power transfer and is far more aerodynamic.
The seat has integrated headrest tubes for a built-in headrest that weighs less than 6 ounces. It doesn't need a clamp but just slides in and out easily yet stays at your correct height. It is very flexible and can comfortably handle rough roads and most bumps without having to lift your head from the headrest.
The tailbox has two integrated bottle holders that are located directly behind the seat and a hinged lid that opens backwards for holding essentials. While the GT tailbox is only slightly larger than the original, it has almost twice the usable space inside and is much stronger.

This RailGun seat follows the contour of the M5 CHR frame and is extremely stiff for fabulous power transfer yet a comfortable ride when under power. Accelerating, climbing and just running under power on this ride is so remarkable and fun it likely has to be experienced to be believed.
By design, the tire interferes with the floor of the tailbox for an M5 CHR by almost three inches with the eight degree seat angle so we made a shaped tunnel insert to fit in the bottom of the tailbox to clear the wheel.
While we have many great testimonials from our RailGun riders, the GT seat surprised us a bit by reducing turbulence behind the seat so much that it creates a better draft at faster speeds than we expected. Our strongest drafting riders just love the new seat now so we thought we would include some of their testimonials this time, instead.
While the GT allows faster speeds so it's even more fun to chase down cars while playing in the road, there is one drawback: the reduced turbulence also reduces the typical reverse draft effect so you don't get same assist when someone jumps on your wheel at speed. This means that when riding with strong riders at faster speeds than they could before, it may be more difficult to drop a strong rider who has latched on...
While our non-competetive riders tell us that their RailGun seat has brought new comfort and life to their riding, we would like to remind people that this seat is not really designed for comfort at low power levels, such as just cruising around. It is a performance seat, designed to provide proper support while under power and might possibly become a bit tedious otherwise. The lumbar support is designed to assist and support the lower back when it is under tension, whether for short sprints or 24 hr ultras. If you ride with your lower back relaxed and not under tension, this seat may not be the best choice for you.
