The Unirack, handcrafted in our workshop, is a seatpost rack designed for offroad riding. Its design is particularly rigid, thanks to its triangulation around two fixing points. Its design pushes the rear bag farther from the saddle than on the supports already available on the market, giving the rider much more freedom of movement. Thanks to its 3D printed mounting kit (Sold Separately), the Unirack adapts to all seatposts in D27.2 and 31.6 and will therefore equip both a gravel and a suspended mountain bike. We did not want to make the Unirack compatible with telescopic seatposts, knowing that in any case the use of a telescopic seatpost would not be suggested with a remote load. Originally designed around the SHAZAM saddle bag from our friends from Wizard Works, the Unirack is compatible with most saddle bags of this type (Zeitgest and Catalyst Pack from Swift Industries, Werewolf from Helmut Equipement, etc). A product which catches interest of TheRadavist and Bikepacking.com! Do you have a question about the product?
