Extention 2026 - first glance

At the end of February 2026 we’ll be getting fresh Extention goodies, including the ASP and Eurus frames.

Our customers already know this, but we feel this is something new to those outside bike trials. Extention is a China-based brand founded by a bunch of engineers with street-trials in their blood. It kicked off in 2019, and since early 2020 it’s been on the Polish market—when we were among the first in Europe to see what all the fuss was about.

Until recently, Extention was mainly known for street-trials bikes, including the Avenger—the first ever street-trials frame made from carbon fibre. They did some experimenting with steel, but it was the aluminium models that really blew up: spot-on geometry and details that, back then, you’d mostly expect from top-tier Inspired builds. These days—largely thanks to Extention—people expect even entry-level street-trials bikes to come with a tapered head tube, a fork with a thru-axle, internal routing for the brake hose through the head tube, and cranks on something more solid than square taper or ISIS.

Almost 4 years ago, the Extention engineers started working on frames for pump tracks and jump lines. In classic Extention fashion, carbon came first—the Espada—and then the aluminium frames followed. The Espada is now in the final stages of designing its second generation and will land in the second half of the upcoming season. Third-gen aluminium frames will be available from us in spring 2026—phone-only. If you’re interested, get in touch.

The first hints that Extention were cooking up something totally different popped up in early 2024 on Pinkbike, in a new-products thread. What we saw was a raw, logo-less carbon frame with a suspension layout similar to DW-Link—no paint, no branding, just a proper spy shot. After a while it was identified as the Extention Eurus. Over two years the frame went through extensive testing, achieving EN-17406-2020-A1 Category 5—the highest category in gravity riding terms. Eurus is built for heavy enduro, and you can find more info by clicking here.

Extention’s newest product is the ASP—an aluminium frame made for bike-park abuse. The whole idea is simple: straightforward design, easy to service, and tough as nails. Depending on the shock and mounting position, the frame runs 170mm, 180mm or 200mm of travel. Details on the ASP are here.

As a boutique-style manufacturer, Extention leans heavily on CNC machining. It’s expensive, but at low volumes it’s the one method that reliably delivers the tolerances and strength they’re after. The entire linkage on the Eurus is CNC-machined, as are plenty of swingarm parts and front-triangle elements on the ASP. Back in the day, trials bikes basically lived on CNC—and we’re genuinely glad to see this kind of manufacturing (which is absolutely in the DNA of niche components) making its way into bikes aimed at a wider audience.

In 2026, Extention will be available from us exclusively as framesets: either without a shock, or with an Öhlins shock—coil or air.
