This product is currently in an early phase of launch on the European market. A small batch is in transit. The frame launch is planned for early March 2026.
We’ve been working with Extention since 2019, when the brand surprised everyone with the world’s first carbon street-trials bike. For 2026 they’re taking things a step further, bringing carbon frames for pump tracks and enduro and the latest offering in the alloy category. The ASP is a beefier version of the Ace 150, designed with one goal: maximum freedom in the bike park. It’s not a machine optimised specifically for DH, FR, or enduro—but it’s built to be fun in all of them.
The suspension system allows for 3 configurations:
- 200 mm travel with a 250x75 shock
- 180 mm travel with a 230x65 shock
- 170 mm travel with a 230x60 shock
Recommended shocks that pair well with the suspension kinematics:
- Linear DH: DVO Jade X, RockShox Vivid Coil, Öhlins M.2 Coil
- Progressive for bike parks: RockShox Vivid Air, Öhlins TTX M.2 Air, DVO Topaz
The seat tube is compatible with dropper posts up to 180 mm travel.
Frame sold without shock.
The suspension layout uses a strongly progressive leverage curve—from roughly 3.4:1 at the start to about 2.0:1 at bottom-out. In practice this gives sensitivity on small bumps and good traction, clear mid-stroke support under hard pedalling and on landings, and strong bottom-out resistance without having to over-stiffen the shock. Anti-squat around SAG is close to neutral (about 100–110% depending on gear), so the bike doesn’t bob excessively when you’re pushing on the pedals, while still staying active on rough climbs.
Under braking, anti-rise goes from near-neutral around SAG to lower values deeper in the travel, which helps the rear wheel stay in contact over small chatter and in steep sections instead of stiffening up. The rear triangle lengthens up to around SAG, then shortens in the deeper part of the stroke. Pedal kickback is low in gears typically used in the bike park, with higher values showing up mainly in the largest climbing cog.
