What They Say...
A Stayer Groadinger UG is a gravel bike built for adventure-groading and fast off-roadin’. The UG is a lightweight steel fun bike designed specifically with the ‘road-to-gravel-to-gnar’ ratio found most often when gravel riding in the UK. This do-it-all gravelling adventure-ready frame set is for 1X or 2X and a carbon or steel fork for packing up or packing light but never packing in.
