Farr’s new Arm Rest Kit isn’t their first go at bolt-on arm rests to extend the comfortable range of their tiny aerobar extensions. But this new setup was developed to be both lightweight and universal-fit, so they bolt onto any 31.8 bar whether you already ride with one of their Aero Bolt-Ons, Aero Gravel bar, Aero MTB bar, or some other wacky-shaped handlebar with a built-in front loop

The Australian endurance riders of Ride Farr are always looking for simple ways to ride farther, and their mini <100g bolt-on aero bar extension seemed like a good place to start, giving a slightly extended extension position to either flat or drop bar riders. But riders soon wanted even more support to hold that aero tuck longer, so they developed a set of armrests that bolted onto the Aero Bolt-On’s mounting brackets. Those were well-received, but limited to Aero Bolt-On users and with limited production numbers.

Now Farr have refined the armrest setup once more with a new lightweight, more modular Arm Rest Kit v2 that is much more adjustable and will add forearm support to almost any endurance bar setup.

The trick to the more universal setup is a lightweight set of forged & CNC-machined 31.8mm bar clamps and adjustable L-brackets to support the simple alloy armrests. Mount them with Farr Aero Bolt-On mini extensions or on their own.

Farr says they developed the low-profile and flatter alloy cup and 7mm thick EVA foam padding shape to offer ideal forearm support and comfort for gravel, bikepacking, and more mixed-surface endurance riding – as opposed to the more curved, cupped shape that dominates a lot of time trial or triathlon style armrests. It looks like this shape will allow riders to move their position around a bit more.

For those looking to dial in fit, there seem to be plenty of options in both vertical & horizontal adjustment, mounted inside or outside of the clamps, in a couple of offsets, and positioning at or almost as low as your bar in some settings.

The entire self-sufficient, universal-fit setup is claimed to weigh 222g (or even a bit lighter if you combine it with a Farr aero bar setup).

    get a full length clipon aerobar, they are so much better, i just the redshift QR one, you can take then on and of in seconds

    You might not need to take the weight off your hands if the bar hadn’t been made so stiff in the central area to begin with?

        Aero benefits aside, this is an effective way to make a stiff bar and my point being that bar stiffness is a part of how long it takes for weight on your hands, vibrations etc to become a problem. I’ve ridden a couple of bars like this and the difference the brace and central section OS width can make is surprising.
