GravelPlus frame that fits road, cross and mountain bike tires. Go anywhere fast!
The U.P. (Unbeaten Path) is the heart of the OPEN range (the U.P.P.E.R. is its superlight partner).
The 3 members of the U.P. (Unbeaten Path) family all combine a road riding position with clearance for your choice of road, cross or mountain bike tires.
Get out of town on tarmac, then hit the gravel roads or switch to singletrack and bridleways. Your position gets you there fast; the big tyres make you unstoppable once you're there.
The frame is available in three versions:
A dropped chainstay means it can be made beefier, and thus stiffer, fox maximum efficiency whilst still keeping an excellent Q-factor.
Skinny seatstays provide just the right amount of cushioning to soften the big bumps. Combined with fat tyres this is a superbly comfortable ride.
All cables and hoses are routed internally, for neatness and protection. With OPEN's MultiStop design, you can customize the frame for 2x10/11, 1x10/11 and Di2 shifting - just change the insert. If you choose to run a single chainring, you can also remove the front derailleur hanger to further clean up the frame.
The 27.2mm inline seatpost provides another bit of flex as well as saving weight.
The U.P. is packed with neat, subtle features, like the toptube bag mounting bolts for longer journeys, or the "pilot hole" that allows a quick visual check that the seatpost is correctly mounted at a safe depth.
"It's not often I am wrong (actually that's a lie...), But I never really got the Gravel scene, and thus I never really got OPEN.
Sure I knew of Gerard Vroomen's involvement and the fact that almost everything he touches turns to gold…
After having ridden gravel bikes I now 'get it'. And OPEN are spearheading this movement.
Cycling is meant to be fun, And know one gets that better than OPEN"

Super-light cross-country hardtail that fits up to 3" tyres for the roughest terrain.
OPEN's ONE+ is a true off-road cross country racer.
Featuring many of the elements which make the U.P. so unique, this model's focus is more towards that of a 'traditional' mountain bike, but updated for the 21st century.
OPEN's signature dropped chainstay allows for a stronger, stiffer design with excellent crank and tyre clearance.
