Fortitude Singlespeed SRP£849.99

The Fortitude is our rigid-specific 29er mountain bike, purposefully designed to negate suspension technolgy. A relatively slack head angle gives a super stable ride and very capable singletrack destroyer despite the rigid fork.

There is a joy to be had in fully rigid riding, it is a form of mountain biking where you are directly connected to the trail, every shift of your body weight, every dab of the brake lever, every pedal stroke, they all count, it’s a simple but beautiful and rewarding way to ride. In an industry where we are always being sold the latest technology sometimes you just want to escape and it’s amazing just how much fun a rigid bike can be. You will become fast, you will start relying on skills you forget you even had and rather than just charging through obstacles on the latest front or fully suspended bike, you will have to pick your lines, learn how to read the trail again and become a better rider for it.

This is Genesis bike designer Dom’s favourite bike and as a fan of Singlespeed riding he wanted the Singlespeed bike to be just that, clean, simple and designed specifically to be ridden with one gear only.

Reynolds 725 Steel

Features

Non-Suspension Corrected Fork

The short rigid fork keeps the front end nice and low and combined with a low BB it allows us to replicate the great handling of a 100mm 26inch hardtail with the rolling advantage of the bigger wheels.

Flattened seat tube

The flattened/squashed seat tube allows a nice tight wheelbase without having to bend the seat tube. It luckily also gives a clean look and ensures straight tubes throughout.

Clean lines - No additional mounts

keep it clean and simple, light and racey we haven’t included any additional mounts, so no rack mounts, no fender mounts, no low rider mounts on the fork. Bottle and crud catcher bosses only.

horizontal dropouts and a slotted disc mount

A horizontal/track end style drop out is still our preferred method of wheel tension, it’s just the most utilitarian design, with the most weight saving and the least amount to go wrong. Just grab the rear wheel, pull it backwards, tighten the axle bolts.
