Building off the momentum of our Cache Titanium release, we wanted to offer a model in steel. Same craftsmanship and overall features as the Ti but in a material that gives a premium ride with the unique feel and durability of steel. Plus, this Cache delivers the versatility you demand for your every gravel adventure, while still leaving a little in the bank to support your next cycling getaway. 

When looking at materials, steel was the perfect option for our second gravel bike. Similar to other substances, all steels are not equivalent and for this model we selected air hardened steel because it’s not only a premium choice, but it’s also malleable so that we could customize and craft the tubing to the exact spec’s we needed. In addition, it’s heat treated to give high strength and durability which means your Cache will deliver for years to come. When in the mountains, it’s compliant nature ensures a comfortable ride for long days in the saddle. Plus, you can load up it knowing that this stable frame can carry heavy loads while still offering a precise and predictable ride.

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. It’s not an industry standard that you’ll find on most bikes, but it’s another detail we’re super proud of.

Check out the full development story here.



In keeping with true Knolly standards, of the seven Cache steel tubes (two top tubes, two down tubes, seat tube, chain stay and seat stay), all are custom and most of them required new or modified production tooling. In particular, we wanted to highlight the Cache seat tube. Instead of being completely straight, our Cache is curved, butted and follows the shape of the wheel. This elegant tube not only looks stunning but it also provides tire and fender clearance and vertical compliance through the seat post to the rider.

We also paid close attention to the design area near the chainstay, where the cross-section changes from a classic oval shape near the BB and tire, to trapezoidal at the dropouts. We’ve provided external chainstay cable routing on the bottom side, for a clean, simple and easy to access location.


While we know that most Cache customers will install a rigid fork on their bike, being predominantly a mountain bike company, we wanted a short travel fork option. This meant that we needed to bend a very large diameter steel downtube near the headtube. We required the downtube to be strong but we also wanted to ensure that we had clearance for short travel gravel specific suspension forks such as the Fox 32 Stepcast AX and MRP Baxter.



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.


Our riders wanted one bike that could deliver the highest level of performance, reliability and durability. With no compromises on features, this Cache delivers.


The Cache steel features a DT Swiss RWS rear axle, custom CNC’d dropouts, supports 1by or 2by, 3 water bottle mounts, rack mounts, and external cable housing with cable guides along the downtube to ensure easy and quick service-ability. This ride is offered in three great colour options: Midnight Blue/Black, Blue Sky Camo, Green Grey. We’re proud of the Cache steel, as we know it will deliver strong on your next gravel, single-track or urban adventure.
