Extention Rise trials bike

Characteristic to Extention, the bike uses a stiff BB24 crankset redesigned for trials use, which incorporates a standard screw-on freewheel. The use of a BSA BB tube and common trials components makes this an easy bike to upgrade.

The geometry is balanced but features a sharper head tube angle meaning the bike is more eager on front wheel moves and feels relatively longer. Mated with high rise Extention handlebars, this is a great offering for taller riders or those looking for a longer bike.

* Please note that this sprocket has a unique design requiring the chain to be installed in the correct grooves. Every other tooth is wider and needs to be matched with the outer links on a chain. This should be kept in mind after replacing the chain or removing the rear wheel.
