ONE-TWENTY RC 300

 

If you like a trail bike inspired geometry and a more relaxed seating position but don't need the 120 mm rear travel our 'classic' ONE-TWENTY brings to the table, then our more XC and marathon focused RC 300 is the perfect choice.

  • Entry-level ONE-TWENTY RC model based on a triple-butted aluminium frame with FLOAT LINK activated 100 mm of rear travel, paired with 120 mm upfront. A super effective mile muncher that loves extended cross country outings as much as fun-packed trail session. Fast-rolling 29er wheels and tyres cover ground quickly and help to create a super smooth ride.

    Completely redesigned for 2019, the ONE-TWENTY continues its success story into the 2022 season. With multiple test successes, including a 'BEST IN TEST' in Enduro Mountainbike Magazine for the 2020 ONE-TWENTY 8000, our mid-travel bike will once again impress with its versatility and unstoppable trail munching capabilities. While very much a trail bike at heart, the modern yet balanced trail bike geometry, paired with fantastic frame stiffness, created a mid-travel bike that is super capable on rough trails but also carries speed perfectly on less technically demanding tracks. And to give riders a maximum choice, we will offer the ONE-TWENTY again in the 'classic' 120 mm rear/130 mm front travel configuration or the slightly more XC biased 100 mm rear/120 mm front travel 'RC' setup, which also has a slightly steeper head angle and seat angle for improved climbing performance.

    To reduce production and delivery times, we are sometimes forced to make last-minute specification changes. Please be aware that those changes might not be reflected on these product pages and images.

    PROLITE 66 TRIPLE BUTTED ALUMINUM

    When creating high-end aluminium frames, we use our proven PROLITE 66 (6066) aluminium, as it is incredibly light and durable. In addition, it works exceptionally well with our hydroforming technology, allowing us to create complex shapes, featuring triple butted wall thicknesses, an almost carbon-like appearance and the best possible stiffness-to-weight ratio. While lesser alloys might be cheaper, it is the ideal choice for high-performance bicycle frames.

    X-TAPER HEADTUBE

    Steering precision is vital to safe and confident handling, and the X-TAPER HEADTUBE allows us to significantly boost this precision. A larger headset diameter at the bottom paired with a smaller one at the top helps to deal with the strains modern riding and equipment can put on the headtube, all without adding unnecessary weight. It allows tapered forks to be fitted with ease and delivers precise and confidence-inspiring steering.

    IMAGE

    SMOOTH WELDING

    This is a process we use to give a nice flat finish to our welds instead of the scaled, 'stack of coins' effect TIG welded joints often have. The welder uses the welding torch to go over the joint twice, helping to smooth out the filler material. It takes a lot of skill to do this, but it delivers strong and smart-looking frames that have the appearance of a carbon fibre frame at first look.

    IMAGE

    INTERNAL CABLE ROUTING

    On the majority of our frames, we run the gear and brake cables and hoses through the frame. The cables enter and exit the frame through smooth sockets, or we use one of our other systems like SMART ENTRY or WIRE PORT to be routed through. Running the cables inside the frame protects them from the elements, gives a clean and neat look and can offer aerodynamic advantages.

    IMAGE

    DOWN TUBE EXIT

    DOWN TUBE EXIT is a feature seen on some of our frames with internally routed cables. By slightly overlapping the downtube where it connects to the bottom bracket, it leaves a small space that allows cables to exit easily. This means they are easily accessible for routine maintenance or replacement, but it prevents excessive movement and noise that can cause wear and distraction.

    IMAGE

    SMART ENTRY

    Many of our frames offer internal cable routing, where the gear and brake cables are run through the frame for maximum protection and a clean look. Some internally run cables can rattle when riding over uneven surfaces, but our SMART ENTRY system prevents this from happening. Cables, housings and brake hoses are clamped under tension to prevent noisy cable movement. All inlets are completely interchangeable to deal with any kind of cable or wire.

    DI2 READY

    Shimano's Di2 electronic shifting system offers fast, smooth and reliable shifting. In particular, in the road world, it has proven itself as the primary choice when top performance is at the top of the agenda. With that in mind, we have a broad selection of performance road frames that are Di2 READY and can accommodate the electrical cable, battery and other little tweaks that the system requires.

    FLOAT LINK REAR SUSPENSION

    A suspension system where the lower shock mount moves as well as the upper link, giving a supple and sensitive feel over bumps. This system allows our engineers to precisely manipulate the leverage ratio, giving ultimate control of the progression of the suspension so that a FLOAT LINK rear suspension system feels like it offers more wheel travel than the numbers alone suggest.

    IMAGE

    NON-SLIP TIGHTENING

    This system means you only need a single tool to tighten important bolts, making it easy to secure them while out on the trail and also making routine maintenance faster and simpler. The bolts have a specially shaped head on one end that fits into a matching recess in the frame, preventing rotation. That means there is no hardware bonded into the frame itself, so damaged threads or bolts can be easily replaced.
