We consider the geometry of Extention bikes to be among the very best with standard measurements not reflecting what makes this bike so versatile - a longer front triangle and shorter fork rake. This is the first short wheelbased street-trials bike to have ample wheel clearance for barspins.
This bike features the 2022 components with updated '23 handlebars. The framesets feature the same geometry and minor structural changes with the chief difference being that they are available in additional colours.
✅ Custom Trialshop.pl upgrade - uprated Sapim spokes
✅ Brake hose installed through steerer tube as standard
