The frame is constructed from carbon using an EPS construction method. A polystyrene mandrel allows the interior of the carbon to be controlled (mandrel shrinks as the carbon has been cured then removed) to shape the cross-section of the tubes. Bold haven't scrimped on carbon and made the main frame, seat and chain stays from this material. The shock is hidden inside the frame's seat tube and down tube junction, allowing clean lines, a low centre of gravity and less influence from the shock and pivot placement across varying frame sizes. All cable routing is internal, and intake ports in the head tube allow air to flow through the frame and exit from ports in the plastic down tube and shock covers, something that Bold says helps to cool the shock, although it's fair to question just how much difference this actually makes. Bold have chosen a Boost 148mm rear axle to allow extra space for 27.5+ size tire clearance and improve rigidity for 29" wheels. An injection moulded chain stay guard has a tab to prevent chain suck, metal protection for the carbon close to the chainring isn't needed and Bold didn't have to compromise the carbon lay up in this area. Last but not least, there's plenty of room for a bottle cage.
The IST (Internal Suspension Technology) positions the shock inside the frame, with it being driven by a short link, and this also allowed Bold to create their desired kinematic as they could use a much shorter link than conventional designs. Bold say the kinematic is slightly regressive up to the sag point for small bump sensitivity, and then linear through the rest of the stroke until the final 20mm of travel when it ramps up for big hits. Unfortunately this shock position means that an internally routed dropper post can't be used.
The bike is designed around a custom DT Swiss 313 shock that measures 200mm x 50mm. The shock, along with the DT Swiss OPM fork, can be controlled using the O.D.L. (Open. Drive. Lock) lever mounted on the handlebar. This allows on the fly adjustment similar to Scott's Twinloc system but with a prettier, slightly more ergonomic lever. 'Lock' is a true lockout mode, and 'Drive' is designed for trail situations, and 'Open' for downhill riding.
Accessing the shock is made simple by removing the plastic down tube protector/cover that's attached by two M3 bolts. From here you can adjust the air pressure, the cable tension for the O.D.L. system and the rebound. Reaching the rebound adjuster is a little tricky, but it gets easier with a little practice. The shock has 40 clicks of rebound to play with, from fast to "is this actually rebounding?" A plastic sag indicator is included, which clips in place of the top shock mount cover - simply line up the markers for desired sag amounts.
