Fashion is so often cyclical, you only have to walk through the 'trendier' areas of your local town or city to see non-ironic flashbacks to the eighties and nineties. So it's no surprise that bike manufacturers are harking back to the good old days with some retro-inspired paint jobs.
The F-Si is Cannondale's raciest of hardtails and this particular one comes equipped with a smattering of very, very lightweight parts.
There's Cannondale's Lefty Ocho fork, its Hollowgram TR carbon wheels with tan sidewall Onza Canis tyres, a SRAM XX1 groupset with a gripshift shifter (for extra retro, and extra lightweight) and Level TLR brakes, plus a load of carbon Cannondale finishing kit thrown in for good measure.
Tom Marvin is a technical editor at BikeRadar.com and MBUK magazine. He has a particular focus on mountain bikes, but spends plenty of time on gravel bikes, too.
Tom has written for BikeRadar, MBUK and Cycling Plus, and was previously technical editor of What Mountain Bike magazine. He is also a regular presenter on BikeRadar’s YouTube channel and the BikeRadar podcast.
With more than twenty years of mountain biking experience, and nearly a decade of testing mountain and gravel bikes, Tom has ridden and tested thousands of bikes and products, from super-light XC race bikes through to the most powerful brakes on the market.
Outside of testing bikes, Tom competes in a wide range of mountain bike races, from multi-day enduros through to 24-hour races in the depths of the Scottish winter – pushing bikes, components and his legs to their limits. He’s also worked out that shaving your legs saves 8 watts, while testing aerodynamics in a wind tunnel.
When not riding he can be found at the climbing wall, in his garden or cooking up culinary delights.
