Better known for its unique Fourby4 linked mountain bikes, Knolly’s gravel bike, the Cache, takes Knolly’s precision ethos and builds it into a gravel-going machine. Now, the brand has given the bike a well-deserved update, making it slacker, suspension fork-ready, and kitting it with clearance for modern tyres. Here are all of the details.

Constructed of custom-shaped titanium tubing, as well as a handful of CNC-machined details, Knolly’s Cache Titanium is said to bring plenty of strength, combined with a comfortable ride feel that’s often attributed to a titanium build. But the bike gets the full heft of the brand’s engineering DNA in a bid to help the Cache take on all kinds of gravel riding.

Knolly says that the Cache Ti benefits from what it considers a modern gravel geometry. First and foremost, the front end is corrected to accommodate a suspension fork, although none of the available builds come with one (a Fox 32 Tapercast is available as an upgrade). Then, to help the bike behave on the climbs, as well as tackle the ever-unpredictable terrain of gravel, a size 58 frame gets a 70-degree head angle, a 74-degree effective seat tube angle, and a 424mm chainstay. That’s while running a 700c wheelset.
Although Knolly is going for an uber modern approach, it offers a level of adaptability. It can be built with a 1x or 2x drivetrain, whether that’s mechanical or electronic, and the Cache can fit up to a 700x55c (29×2.1) tyre in the rear, as well as a 60mm tyre (2.3in) up front.

The bike’s then loaded with all of the mounts for racks, mudguards, bags and bottles for multi-day expeditions, and it’s compatible with UDH derailleurs and mech hangers.
The Knolly Cache Titanium is available in seven sizes and five builds, with frames starting at $4,439, frames and forks starting at $4,919, and complete bikes starting at $8,279.
