Open U.P Σκελετός Gravel




  • With road tires, it is a very fast road bike
  • With big road/cross/gravel tires (32-40mm), it’s a go-anywhere bike perfect for mixed surface rides and most gravel routes
  • With 650b mountain bike tires, it's unstoppable on very tough terrain yet much faster on pavement than you'd expect thanks to the road position


So the position lets you get out of town and reach the gravel/dirt/trails quickly (unlike a mountain bike). Space for big tires lets you tackle any route (unlike a road bike). And you can do that with one type of tire for everything or finetune your ride with multiple wheelsets or tires.
