Kona has updated its Process 134 trail bike with an all-new chassis and geometry, plus 29" and 650b wheel size options with carbon or aluminium frames available in both. It still delivers 134mm at the back and 140mm up the front, but now with Kona's more modern layout.

The new bike is still a linkage driven single pivot design, but the layout takes its cues from the bigger travel Process 153 range, with a chunky rocker link driving a vertically mounted shock. It also means there's greater seatpost insertion depth, so you can run longer travel dropper posts.

While the old 134 only came with 650b wheels and an aluminium frame, you can now pick from two full-carbon fibre (including the chainstays) and two aluminium 29er builds or two aluminium-only 650b models. The big wheelers are said to have their geometry derived from the minor cult classic that was the short travel Process 111, with respectably long, slack and low geometry.

The suspension is also said to have 'improved' anti-squat - we're guessing that means there's more of it to counter the somewhat spongy pedalling characteristics of the old bike - and all the bikes use de-rigeur trunnion mounted, metric-sized shocks.

We're waiting on UK pricing for the bikes, but we'll update this when we do have it. In the meantime, check out the range below.
