Extention Avenger street-trials bike

-> Brake hose installed through steerer tube as standard

The original carbon fibre street-trials bike is back in a beautiful light pearl yellow finish. At under 9.3kg as pictured, this is among the lightest street-trials bikes out there, and also one of the stiffest. The frame features a responsive geometry with a short wheelbase and sharp head tube angle - the same across the entire Extention lineup - which has become the gold standard among 24" street-trials bikes. Dropouts are spaced at 142mm with dedicated adaptors available to reduce spacing to 135mm. Both the frame and forks feature an internally routed brake hose for a clean aesthetic, which additionally reduces the risk of hitting and damaging the hose.

Braking is taken care of by the latest Hope Tech 4 Evo Trial Zone brakes which offer superior braking performance and extensive lever adjustability allowing you to dial in the perfect setup. Wheels are built on Extention thru-axle hubs, with the rear featuring 120 engagement points. In combination with a powerful, adjustable chain tensioner which removes all chain slack, the drivetrain is very responsive with over 160 effective engagement points at the crank. Extention's A35 rims and Continental tyres are both tubeless ready, allowing an extra 300g in weight reduction, though the bike does feature inner tubes. The crankset is Extention's proven BB24 system which is both light and stiff. In the cockpit you will find 740mm wide carbon fibre handlebars and Extention's latest lock-on grips which have a firm yet soft feel to them.
