Cortex, the next generation

The next generation of Cortex features new suspension updates, geometry tweaks, and SRAM UDH.The 29er setup allows for a comfortable, responsive and joy-inspiring ride. Crafted from 6061 alloy, Cortex offers a stiff, sturdy frame (and with that all important bottle space!) to withstand a variety of riding. From big days out on the trails to trips to the bike park, this next generation sees improved suspension performance and greater balance, allowing riders to tackle varied terrains with the bonus of all-day comfort. Cortex is a reliable choice for the all-round off-road rider.

The all new suspension updates for Cortex sees an increase of suspension on rear taking it to 135mm of travel, offering a win-win for riders with no extra weight or loss of pedalling performance. The changes to the suspension leads to improved kinematics of the frame; supple off the start, stable mid-stroke which ramps up for a bottomless feel. This paired with the new variation in chainstay length gives riders a more balanced feel, adding to rider comfort and capabilities whether you’re hitting the trails or days at the bike park.

Constructed using 6061 Alloy, which is known for its strength and lightweight properties, Cortex offers a stiff and reliable ride across a variety of terrains. Plus, featuring SRAM UDH removes potential barriers riders may have when it comes to parts and repairability. From clipping rocks, to mid-race mishaps, SRAM UDH makes it easy to get back rolling.

With 9 customisable options available, from framesets and Shimano Deore to SRAM X0 Eagle Transmission, each individual riding style is catered for. With prices starting from £1,599, Cortex offers a competitive price point, not only making off-road riding more accessible, but also giving riders more bang for their buck.

With ten shop-in-shops across the UK, Sonder offers a unique experience where every bike and wheel is built to order. Renowned for its exceptional service, custom options, and bespoke bike frames, Sonder stands resilient and poised for continued success throughout 2024. Sonder is committed to supporting the evolution of multi-disciplinary riders.

    Interesting, love my gen 1 Cortex and had been contemplating a switch to the Evol frame and a parts transfer but that could be more bike then i want for majority of my riding  (really want a Cotic Flare). This would seem to cover all requirements, will have to have a sit on one in store at the next opportunity.

    Hm, wonder if they will knock out any gen1 frames are a nice price. I’ve got a 120mm SID that is just begging for a 120mm frame to go with it!

    Nice. But …

    prefer more travel. Prefer shocks aligned with the seat tube rather than the top tube.

    I do like my Evol but it’s unfortunate for the Cortex that the Chisel FS came out last week…

    And you have to spend £3k to get a fork that’s not shit.

    I agree with this, but the Chisel will be way lighter than this, so an XC bike vs trail bike. They even call the frame “sturdy” in the blurb.

    Which is also very similar to a Giant ATX990 and every bike that has a similar outline in the 25 years since.

    You realise there’s a chance they come out of the same factory, or if not – that the Taiwanese factories use very similar frame parts and construction techniques?

    You weren’t suggesting there was copying gong on or anything like that?
