Entry level street-trials bike from new brand Extention, the Heimdall features a 15mm thru-axle and an internally routed front brake hose - features not found on any other bike at this price point. Horizontal dropouts are coupled with excellent chain tugs and massive M10 bolts - an important addition to firmly secure the rear wheel.

Heavily updated for 2023, the Heimdall features more robust rims, updated drivetrain and new frame colours. Small tweaks, visual and structural can be found throughout the bike.
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.
✅ Custom Trialshop.pl upgrade - uprated Sapim spokes
