FastTT Pro-RS Triathlon Aero Bars
The FastTT Pro-RS is a next-generation carbon aerobar system designed for triathletes looking for a highly aerodynamic setup without sacrificing adjustability, comfort or long-distance stability.
Using a twin-arm design, the Pro-RS allows each side to be positioned independently, giving considerably more flexibility than a fixed monobar system. The extensions are constructed from hand-laid UD carbon fibre and finished in a natural satin carbon finish.
Independent wind-tunnel testing commissioned by FastTT showed the Pro-RS to be 23.2 watts faster than a conventional armrest and extension setup, while also showing a 5.9 watt improvement over the FastTT 2.1 and 10.1 watts over the FastTT 2.0 under the tested conditions.
Key Features
Hand-laid UD carbon fibre construction
Independent twin-arm design
Highly adjustable cockpit positioning
Aerodynamically shaped arm supports and extensions
Adjustable elbow width
Additional narrow-fit arm pads available
Integrated computer mounting options
Garmin and Wahoo compatibility
Designed around approximately a 25° extension angle
Compatible with Shimano Di2
Compatible with SRAM AXS / Clics
Compatible with Campagnolo EPS
Tested beyond ISO 4210 safety requirements
Natural satin UD carbon finish
Choosing Your Size
FastTT sizes the Pro-RS according to your forearm and hand measurement.
Measure in a straight line from the first joint of your little/pinkie finger to the rear of your elbow bone.
Medium: 330–365 mm
Large: 365–400 mm
X-Large: 400 mm+
If you fall directly between two sizes, FastTT recommends sizing up.
If you are unsure which size is correct, contact More Aero before ordering and we can help confirm the appropriate option.
Aerodynamic Performance
According to FastTT’s independent wind-tunnel testing:
23.2 W saving versus a conventional armrest and extension setup
10.1 W saving versus FastTT 2.0
5.9 W saving versus FastTT 2.1
Actual aerodynamic savings will vary depending on the rider, position, bike and complete cockpit configuration.
Fit & Compatibility
The Pro-RS is designed to work with FastTT’s range of bike-specific mounting solutions, adapter plates, risers and accessories.
Standard configurations allow approximately 270–295 mm of arm spacing, with narrower setups of approximately 240–269 mm possible using the Narrow Bracket Kit.
Compatible electronic shifting systems include:
Shimano Di2
SRAM AXS / SRAM Clics
Campagnolo EPS
The Pro-RS is not designed for conventional mechanical bar-end shifters.
Bike Compatibility
The exact mounting hardware required depends on your bike and existing cockpit.
FastTT offers a range of bike-specific adapters, risers and mounting solutions. If you are unsure what is required for your bike, contact More Aero before ordering and we can help configure the complete setup.
Need Help Configuring Your Cockpit?
FastTT systems can vary significantly depending on the bike, cockpit, desired stack and reach, elbow width and hydration setup.
If you are unsure what you need, contact More Aero with your bike model, size and current cockpit and we can help specify the correct Pro-RS size, mounting hardware and accessories.
