We decided to create a universal frame. What does that mean for us? First and foremost, we were inspired by gravel bikes and their approach: one bike for training, touring, commuting, and fun. However, we decided to move it slightly away from its road cycling roots and further increase its flexibility. The interchangeable dropout system allows for easy mounting of various standards of components and hubs. You can convert the bike to a single speed, an MTB drivetrain, an internal gear hub, or even a fixed gear. What's more! Thanks to the split, there's no problem with mounting a belt drive either. One frame, dozens of possibilities! A lightweight steel bike for many applications!
On this universal frameset, we build Fitness bikes with flat handlebars or Gravel bikes with drop bars. There's also no problem with mounting a suspension fork if the need arises. A trekking bike? We're all for it too! Bikes based on this frame can be found in our online store here.
A belt-driven bike offers minimal maintenance, cleanliness, and a smooth ride. Many times more durable than a chain, it doesn't require lubrication or frequent tensioning. However, if you get tired of it, you can easily convert this bike to any other drivetrain (including a road one).
To increase stiffness, you can optionally choose a frameset with thru-axles in both wheels.
The frame is sold raw with a black fork.
The set includes: frame, fork, rear triangle dropouts, and frame cable guides.
We offer painting services or assembly of your dream bike.
