The new TriRig Alpha One introduces an entirely new mounting and adjustment method to triathlon aerobar extensions, making us wonder how no one thought of this before. Using a single pillar to raise and lower the aero assembly, a single bolt lets you fine tune the height without spacers or other cockpit adjustments. Quite simply, this is brilliant.
The design erases the headaches of other systems, and hides all of the cables, wires and hoses, producing a very clean (and very aerodynamic) front end. And you still get a massive range of fit adjustments for tilt, elbow pad placement, and length. Here’s the video:
All bolts are easily accessible, so you don’t have to move one thing to adjust another. And they all use a 4mm hex wrench, minimizing the number of tools you need. Even better, it comes with the beautiful Silca allen wrench!
It comes with 10mm, 20mm and 40mm lower spacers to set the stem’s height on your steerer tube. Then, trim the steerer to finish just under the included cover plate, which hides that and any cables, wires or brake hoses, shooting them out the back. There’s also a universal fit front brake port underneath that allows for brake lines to pass through…or acts as a cable stop for center pull style mechanical rim brakes.
The extension mount is full carbon and fits any standard round extension. Two bolts at the back allow tilt adjustment, and five boss mounts fit standard front bottle cages and other triathlon accessories.
One of the biggest benefits to the system is that you can continually refine your position and fit without having to order any additional parts, spacers, etc. It’s all easily adjustable through the full range right out of the box.
The base bar, Monopost riser and attachment platform are all carbon fiber. Including arm cups and extensions, the system weighs in at a claimed ~900g. Retail is $999 for the system, with the aerobar extensions being sold separately (but included free during their Black Friday sale!).
