Details

The Otso Fenrir is a ride-anywhere bike for bike-packing races and afternoon adventures alike. It can be built with drop bars or with MTB bars and both selections are available as stock build options. A tire clearance of 29” x 2.6” or 27.5” x 2.8” keeps the Fenrir rolling on rough terrain, while the extra frame and fork braze-ons are ready to carry gear for days or weeks on the trail. Like all Otso bikes, the Fenrir has adjustable geometry via the patented Tuning Chip rear dropout system that makes the bike as adaptable as its rider.

VERSATILITY
While all Otso bikes are known for their versatility, the Fenrir might be the most versatile yet. It was designed to accommodate drop bars with a 50mm stem or MTB bars with an 80mm stem. It can be built with gears or single speed, with a suspension fork or rigid, with a mechanical or electronic drivetrain, or with a dropper or rigid seat post. The ability to fully customize the build of the bike makes the Fenrir as versatile as its rider.

FENRIR WITH DROP BARS
The Fenrir was designed with the option to be built with drop bars or MTB bars. When configured with drop bars, the Fenrir rides like an extra-capable gravel bike. The relatively longer top tube means a shorter stem is needed with drop bars to align with the rider's preferred reach. It can be built with standard road/CX/gravel bars for rides on local trails or with wider bars to fit a handlebar roll loaded with lots of gear.

FENRIR WITH FLAT BARS
When built with MTB bars, Fenrir rides like a 90s XC bike. It's fun and lively, yet efficient and Capable with a capital C. It can handle any sketchy descent or technical climb with ease. Because the top tube is relatively short for a mountain bike, a longer stem (80-90mm) is ideal for maintaining reach. Ride it on your local singletrack or load 'er up for that backcountry tour that you've been dreaming about--you know the one. However you choose to build it, Fenrir will ride any road/trail on the map and carry all the gear to get you there.

DESIGNED FOR BIKE-PACKING
Every last feature of Fenrir Ti is optimized for bike-packing. The titanium frame is strong, smooth, and lighter than steel. It can be built with flat bars or drop bars depending on your affinity for large handlebar rolls. Single-speed is an option for folks who like simplicity while touring. It has extra mounts on the frame and fork for hauling all the gear you'll need for days (or weeks) on the trail. The frame and fork can clear 29" x 2.6" or 27.5" x 2.8" tires for trails that are especially gnarly. No matter your destination and how long it takes to get there, Fenrir Ti is ready.

SINGLE SPEED
All metal Otso bikes have the option to be built single-speed or with gears. Fenrir is included in that group because it has a small notch on the rear dropout near the Tuning Chip. If you build your Fenrir with gears but want to convert to single-speed later on, there is a single-speed Tuning Chip ready to order alongside other accessories. There's no wrong way to build your Fenrir.

SO MANY MOUNTS
A bike-packing bike needs to be able to carry all the gear for days or weeks on the trail. Fenrir has mounts for bottles, fenders, and racks. The Enve fork also has three-pack mounts on either side for sharing the load.

CAPABLE GEOMETRY
Pick a trail on the map and ride it. Fenrir has the endurance of a gravel bike, with the stability of a mountain bike. Above all, it is Capable with a capital C so you can stay the course and reach your destination.

DROPPER FRIENDLY
A small port near the bottom of the seat tube allows for the cable routing of a dropper post. If you don't ride with a dropper, you probably won't even notice the port.

AMPLE CLEARANCE
Tires need to meet the demands of the trail for traction, stability, and comfort. Fenrir can ride up to 29" x 2.6" or 27.5" x 2.8" tires.
