Cache Steel
The Knolly Cache Steel is our second gravel bike model, giving it the unique feel, durability and damping characteristics that you want for long days in the saddle. It includes all the features you want for multi-day adventures, while still being ready for short local training laps.

Steel
We chose air hardened steel because it’s malleable and it allows us to craft the tubing to the exact spec’s we need. Our steel is heat treated to give high strength and durability, and its compliant nature ensures a comfortable ride for long days in the saddle. Plus, all our steel tubes are butted so that the walls are thicker where it’s welded and thinner in the middle. This reduces weight while ensuring you have the strength needed for welding the tube ends.
Carbon fork
A new carbon adventure fork, with added tire clearance for 700*55c (650*2.4"), triple cage mounts for fenders and panniers, 398mm Axel to Crown and an adjustable offset of 47mm or 52mm.
Progressive geometry
Utilizing our mountain bike expertise, we wanted to offer a bike that felt comfortable on both short and long-haul rides, as well as multi-surface terrains. We designed the Cache with a longer front center and a shorter stem to ensure it had optimal handling to expertly manage technical corners, while still being predictable, stable and comfortable on epic adventure rides.
Butted tubing
All our steel tubes are butted so that the walls are thicker where it’s welded and thinner in the middle. This reduces weight while also ensuring you have the strength needed for welding the tube ends. In addition, we know you’re going to push this bike hard in all weather conditions, so we applied an ED anti-corrosion coating on the interior and exterior of all our tubes.
Human Centric Sizing
We have always believed in human centric sizing and design our bikes to deliver optimal reach, standover height and geometry for a broad range of riders.
