Brand: OneUp Components

The benchmark minimalist top guide: just 40 g, yet built from a machined 7075 aluminium body with a glass-reinforced thermoplastic guide. Its standout trick is a tool-free flip to swap the upper guide, plus 7.5 mm of chainline adjustment and a crank-on install, covering 26T to 38T on Boost and oval rings alike.
