Fredbar for sale as seen on Bikepacking.com and other site's and used by the likes of Jay Petervary on the Divide. It's an ingenious solution for giving a more comfortable position when using an aero bar for bikepacking.
It attaches to your steerer above your stem which lifts the aero bar position up and rearward.
It requires you having at least 0.625 of an inch of steerer above your stem to clamp it.
They are currently costing about £150 to ship from the US to the UK. I'm asking £80.
