Cheers to peaceful evening rides on the west side!
MarkJay Acosta loves riding at night. He took these shots in the Presidio of the prototype Alta Vista, the new rim brake mixte we will be releasing November.
The geometry of the Alta Vista “flat bar gravel” and it is 27.5” wheel specific.

Choco sent us this snap of his CUBE Bikes recently converted to our Gullwing flat bar.
((Back in Stock!))
The Gullwing was designed to be the most natural way to adapt a road bike to flat bars while still retaining your integrated road shift/brake levers.
Now that electronic shifters have blips, the shifting ergonomics can be fine tuned

Un mini-vélo in France!?

Style for miles build of our Soma Rufus by Rose Mechanic. That orange chainring by Gabriel is more than icing on the cake!

Ready to smooth out your commute, get coffee or turn heads at any local social ride.

💪 As capable as it is fun. philipp carries a mini fridge on our mini velo, the Rufus! Small 20” wheels help keep the rack low and the load more manageable. 👨🏻‍🔬

We don’t recommend trying this on a 32er.

The new “It Takes Two” tandem frameset is designed for chill backswept Bosco/Albatross/Promenade style bars, but still allows you to maneuver and put on some speed.
