Extention Bikes 

A relatively new player in the street-trials scene, Extention is an active brand in China known for releasing the first ever carbon fibre production street-trials bike named the Avenger.

The focus on affordable functionality shows in features such as an internally routed front brake hose and 15mm front thru-axle being present on all models.

All of Extention bicycles share the same frame geometry with a streety appeal thanks to the short wheelbase. While this is highly subjective, we consider the geometry of these bikes to be among the very best this sport has seen. Despite the similarity to other short bikes on paper, these bikes feature a unique characteristic thanks to geometry tweaks which go beyond - and are not reflected in - the standard bike measurements.
