NEW Wolf Tooth 8-Bit Multi-Tool System + Otso Fenrir Ride-Anywhere Stainless Steel Bike + Feature Video

otso fenrir review

Otso Fenrir Stainless Steel Bike

“The Otso Fenrir is a ride-anywhere bike for bikepacking 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 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.”

“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. The ability to build the Fenrir with different handlebar styles allows the rider to customize the bike to their riding style. When built with drop bars, the Fenrir rides like a gravel bike with extra helpings of capability and confidence. With MTB bars, the Fenrir is lively, fast, and rides like a capable 90s XC bike. Both configurations are meant to ride any road or trail on the map and carry all the gear necessary to get there.”

“The Fenrir frame is made with custom-butted austenitic stainless steel for a smooth ride and corrosion resistance. It is available in five sizes, from XS to XL. Build it with gears or single speed, with either mechanical or electronic geared drivetrains. The Fenrir has a head tube angle of 68º, a seat tube angle of 75º, boost spacing, and 88mm of trail. It comes stock with a carbon ENVE Mountain Fork that has three-pack mounts on either side and a reversible dropout chip for adjustable rake. The Fenrir can accept a suspension fork with up to 100mm of travel, has routing for a cable-actuated dropper post, and has rack and fender mounts. All build options, from handlebar type, to wheel size, to tires, to drivetrain, to anodized color accents and more can be selected on the custom bike builder.”

“Present on all Otso bikes is the Tuning Chip rear dropout system, which allows the rider to adjust the bike’s geometry. This is essentially a dropout with three fixed positions. The Tuning Chip can change the wheelbase by up to 20mm, the bottom bracket height by up to 4mm, and the head tube angle by 0.2º. The front position is made for agile handling on winding trails, with a shorter wheelbase, higher bottom bracket, and steeper head tube angle. The back position of the Tuning Chip is made for a stable, confident ride on sketchy terrain, with a longer wheelbase, lower button bracket, and head tube angle with more slack. Changing positions of the Tuning Chip takes 5-10 minutes and can be done in a home workshop.”

Wolf Tooth 8-Bit Multi-Tool System

“The new 8-Bit System is a group of multi-tools designed to work together to solve most trailside fixes. They are lightweight, strong, versatile, and small enough to fit in a jersey pocket or riding tool wrap. The 8-Bit Chainbreaker + Utility Knife Multi-Tool and the 8-Bit Tire Lever + Rim Dent Remover Multi-Tool join the 8-Bit Pack Pliers to complete the system. The three neatly nest together using magnets and clever machining for compact storage.” – Gravel Cyclist HQ has one of these complete kits in for review, watch this space…

“The 8-Bit Chainbreaker + Utility Knife Multi-Tool has three functions. It has a chainbreaker on one end and a retractable utility blade on the other. The chain tool is operated by an included 3mm hex L key that doubles as a tire plug inserter. A machined slot fits the L key and converts the entire multi-tool into a tire plug inserter, with the forked end of the L key extending outward. The handles of this multi-tool slide open to provide storage for tire plug inserts, a valve core, and a spare mini utility blade.”

“The 8-Bit Tire Lever + Rim Dent Remover Multi-Tool has two functions. A slender, ergonomic plastic tire lever is on one end opposite of a machined aluminum rim dent remover. The tire lever will work with all tubed and tubeless tires, while the rim dent remover is compatible with all metal rims.”

The 8-Bit System takes its name from the 8-Bit Pack Pliers (link to our review here), as the two new multi-tools have the same silhouette and nest neatly together. The 8-Bit Pack Pliers Multi-Tool has 17 functions. On one end of the multi-tool, an 8mm swivel head serves as a driver for the bits that are stored inside: flat head #3.5 and phillips #2 screwdriver bits; 2, 2.5, 3, 4, 5, and 6mm hex; and T10 and T25 Torx-compatible bits. A spoke wrench and valve core wrench are stored on the back and a rasp is on the inside of the upper handle for clearing sealant from valve stems. On the other end of the multi-tool, pliers for master link installation/removal and tightening/loosening of valve stem nuts.”
