The Groadinger UG is being retired as we evolve our frame lineup for 2026.
This is the final production run, and the remaining UG26 frames are already in paint with a 4-week turnaround.
Our ultimate adventure-gravel machine, the UG has defined Stayer’s mixed-terrain ethos for years — fast off-road, planted on descents, and ready for big-day exploring.
Once this final batch is gone, the UG is gone for good.

The Stayer Groadinger UG26 frame is the ultimate adventure gravel bike, built for fast off-roadin’ and adventure-groading. Designed for riders who crave versatility, this lightweight steel frame balances road, gravel, and gnar — perfect for UK terrain and for anyone seeking a do-it-all gnar-steed.
Additionally, it supports 650b or 700c wheelsets, 1x or 2x drivetrains and works with either carbon or steel forks — perfect for packing up, packing light, but never packing in.

With clearance for 2.1″ tyres (650b) or 45mm (700c), the UG26 thrives in gravel, ultra-endurance, and road scenarios. Thereby proving itself equally at home as a gravel beast as it does as a smooth, fast road machine.
“Simply put, it’s a classic.”
“It’s difficult to put into words how much I adore this bike without my review reading like a love letter.”
