2025 Select+ specification of the Heimdall, supplied with Extention's latest freehub, 16T CNC sprocket and Spank-inspired AS35 rims capable of running tubeless. The 2 part bashring is replaced with an integrated, CNC machined Storm bashring.

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

✅ Brake hose installed through steerer tube as standard
