Knolly’s full mountain bike range, which spans four models nad 138mm to 168mm rear travel, is getting a reboot with shapely new frames and mildly updated geometry.

These prototypes shows new tube shaping and the move to a straight top tube, which gives them lower standover height and the ability to run longer-travel dropper seatposts.

They’re stretching the wheelbase slightly and making the seat tubes a bit steeper on larger frame sizes, helping put taller riders in a more balanced position.

All of the bikes use their FOURBY 4 Suspension platform, which uses a multi-linkage upper link that separates wheel path from leverage ratio and lets them tune each more specifically. They use a linear-to-progressive spring rate, so you get the supple, active performance in the beginning and mid-stroke, with more support near bottom out.

A two-position lower shock mount let’s you tweak the geo slightly, too.

Note the lower (upper) linkage directly in front of the rear tire, followed by an upper rocker arm, and you can see how FOURBY 4 is different than others.

Knolly Endorphin is an enduro bike for shorter riders

The 2023 Endorphin 27.5” breaks tradition, with all of their other models running 29er wheels. It’s their first bike to come in an XS size, giving shorter riders and kid shredders an option.

The rear end has 150mm travel, and they’ll likely have builds with 150mm and 160mm forks. This model is shown with a mullet setup, 27.5″ rear and 29er front, so that may be a stock option, too.

Like the others, it gets the new straight, heavily shaped top tube and straight seat tube. No word on pricing or availability yet, we’ll update as we get it.
