Description

The Planet X RT-80 is packed with the latest design features and build technology and is specifically tuned to soak up road buzz, whilst efficiently transforming every watt of your pedal strokes into instant speed.

Balancing your desire for performance with day-long riding comfort, the RT-80 combines refined geometry and advanced design features to offer a smooth, more compliant ride - perfect for those long days in the saddle.

The RT-80 frameset marries a precisely tracking, full carbon fork with our newest lightweight frame, both meticulously crafted from Toray's finest T800 carbon fibre. Our Tri-Tube rear triangle seamlessly blends oversized chainstays with thin and flat seat stays and a narrow 27.2mm seat tube to provide comfort enhancing vertical compliance. Internally routed cabling reduces aerodynamic drag and provides an uninterrupted visual flow. The RT-80 frame is the perfect mix of comfort and efficiency, making the most of every one of your pedal strokes.

Constructed from high quality Toray T800 modulus carbon fibre makes the RT-80 perfect bike for sports riding such as sportives, as well as general recreational riding. A precisely tracking front end is combined with a vertically compliant rear triangle to provide pedalling efficiency and comfort in equal measure.

Created with our 'EPS Inside' moulding technology, each main tube frame junction in the RT-80 is laid up over pre-shaped EPS formers. This allows for a more accurate placement of carbon in the mould, eliminating material wrinkles, creating lighter frames with enhanced structural integrity and allowing absolute consistency from frame to frame.

Groupset: Shimano's Ultegra groupset has been upgraded and the result is the incredible Ultegra 8000 groupset. Shimano have worked to improved the efficiency of the shifting, improved brake feel and delivers a smoother working, better-looking groupset that's simply worth every penny.

Equipped with an 11-28t cassette and 50/34t chainset this RT-80- is ideal for novice and returning cyclists and those seasoned riders looking to push themselves in the hills. If you've not tried the most modern Shimnao groupsets yet you really owe it to yourself to see just how far they've advanced since your last bike was new.

Wheelset: Fulcrum Racing 900, 700c clincher wheelset. Fulcrum wheelsets excel at delivering serious value for money and their Racing 900 model is no different. Built with black anodized, stainless steel spokes, CNC machined hubs fitted with precision cartridge bearings, and all laced to shallow profile alloy rims with a machined braking surface this is a quality wheelset. A Shimano/SRAM 11-speed compatible freehub makes this a versatile wheelset for most types of road cycling. Weighing in around 1800g they're right on the money for a do-it-all wheelset. Tough enough to sprint, light enough to climb on and a pleasure to ride all day, the Fulcrum Racing 900 wheelset will be with you mile after mile.

The RT-80 is the ideal bike for any serious cyclist looking to step up to the latest technology, geometry and design features. The RT-80 blends nimble handling with reassuring stability. It's a bike that flatters riders and shows you how good a rider you really are. Welcome to the future of cycling, NOW! The RT-80 is a bike buying decision you will never regret.
