We put Trek’s off the peg Superfly FS 9.8SL through its paces a few months ago, and were mighty impressed with what we found. But this custom iteration of the bike takes performance and personalisation to another level.

Frame and equipment: featherlight full-susser, meet kit box of delights

The 9.9 series frame has not only the carbon seatstays of the 9.8, but chainstays too, saving 100g and making this one of the lightest full suspension frames available. It’s just 1650g without the Fox rear shock.

While there’s a stock 9.9 XTR option, Trek offered us the chance to try its Project One custom program to create our ultimate Superfly. The process starts with choosing a huge range of paint finishes including the ultralight subtle sheen ‘Rainforest Vapor Coat’ we opted for.
