    Tuning Chip Technology on Otso Bicycles: Everything You Need To Know

    What is the Tuning Chip, and what does it do?

    Our patented Tuning Chip rear dropout system is found on all bike platforms in our collection, and adds an element of versatility to any Otso Cycles bicycle purchase that can make your bike feel like three different machines.

    The Tuning Chip has three different positions, and each position gives each of the bicycles in our lineup a different riding experience. You can adjust your wheelbase by as much as 20mm, and your bottom bracket height by as much as 4mm. In the rear position, you’ll find more stability and comfort and a lower bottom bracket height, as well as have maximum clearance for larger tire sizes. Switch to the front position to get more agile handling and responsiveness, as well as a higher bottom bracket height. In the middle, well, that’s the best of both worlds.

    The Tuning Chip can easily be switched at home with just a few tools and this simple guide. All parts can be replaced if needed.

    A Simple Guide to Adjusting Your Tuning Chip

    Tools needed:

    Tuning Chip Installation and Adjustment Instructions:

    1. Remove rear thru axle using a 5mm hex wrench, then remove rear wheel.
    2. Remove left and right dropout nuts using a 20mm socket (never use a cone wrench or adjustable wrench).
    3. Loosen M6 bolt on left dropout one full rotation only using 5mm hex wrench. Do not loosen this bolt more than one rotation, unless steps 4 and 5 are particularly difficult. If you have to loosen more, make sure to hold the T Nut so it sits in its intended slot behind the dropout.
    4. Remove both right and left Tuning Chip. Use a screwdriver to push from the back if needed.
    5. Slide dropouts to new location and replace Tuning Chip in desired new position (or install new Tuning Chip if needed for desired position). Note that it will also be necessary to slide the brake hose and derailleur cable forward or back.
    6. Thread dropout nuts on by hand until snug, then tighten to 18-20 Nm using a torque wrench.
    7. Tighten dropout slider M6 bolt to 10 Nm using a torque wrench.
    8. Replace rear wheel and axle and tighten axle to 12 Nm using a torque wrench.

    Notes:

    Always adjust the rear derailleur B-screw after changing chip positions. Familiarize yourself with properly adjusting your rear derailleur using the manufacturer's user manual or by bringing your bicycle to your local bike shop.

    Chain length may also need to be adjusted when changing chip positions.

    Rear Tire Size Compatibility Charts for each Tuning Chip Position

    Each Tuning Chip position affects the rear tire compatibility, so we've included this section to help determine which rubber you can safely pair with your Otso build. The further back your rear wheel sits, the wider the tire that will fit.

    Regarding front tire compatibility, if using something other than the Voytek carbon fork on the Voytek, or the Lithic Carbon Fork on the Waheela C, Waheela S, or Warakin, please check with your fork manufacturer for their recommendations on maximum tire size.

    Bikepacking on a School Night

    Bikepacking laughs at the best laid plans. That’s just how it is. At least that’s how it’s been in the half dozen or so trips I’ve been on. Extreme heat, severe weather, closed restaurants, miles of mud, just so many bugs, full campgrounds, also wrong turns. This particular trip had four of the aforementioned inconveniences.

    Lake Byllesby Regional Park is 23 miles from the Otso shop in Burnsville, or 40 miles if you plan a route that uses as many gravel roads as possible while remaining somewhat direct. The park itself is on a reservoir on the Cannon River, just east of the town of Cannon Falls. When I was a kid, my Cub Scout troop took yearly trips to the scout camp on the south side of the lake. This part of the state is known for brisk rivers and farm fields that yield to hardwood forests limestone bluffs. Our overnight trip would be my first time returning to the park in 25 years. I was excited.

    Then came the day of the trip. A cluster of storms rolled in by 2pm, just three hours before our planned departure time of 5pm. “It’ll pass and we’ll have perfect riding weather by the time we need to leave,” we thought. Three hours later, the rain was still coming down. With our bikes loaded up with gear, it would’ve been a heartbreaking defeat to unpack everything and reschedule. “Let’s leave at 6pm. It’s supposed to clear up by then,” became our next optimistic plan. We departed the shop at 6pm as planned, but the rain did not clear up. Instead, we biked for two hours through thick mist, drizzle, rain, and brief downpours.

    At 9:30pm, a full 90 minutes after our forecast arrival time, we rolled into Cannon Falls to find bar kitchens closed at 9pm. When you’re soaked and caked in mud and sand from the waist down while riding for over three hours, you rely on motivation to get you to your destination. That motivation for me was a bacon cheeseburger as my proverbial carrot on a stick and I sure as hell wasn’t about to let a kitchen closure crush my grilled dreams. Through some combination of shoddy salesman skills and survival mode, I was able to convince a cook to keep his grill fired up for one extra order. A round of double bacon cheeseburgers and pints of the finest house ales all around! This was the fourth time that food saved my life.

    By the time we paid up at the bar and headed to the campground, it was 11pm. A local junior sheriff deputy found it odd that five grown men were entering the park on bicycles. “You biked here from Burnsville? And you’re going to camp? Then you’re going to bike home in the morning?” The conversation was like convincing someone that Santa exists. After 30ish minutes, he left, allowing us to spend the night. It was 11:30pm by now.

    An early morning thunderstorm sat overhead from 3:30am-5am. The alarms that we set were no longer needed. Fortunately, the storm passed and we were able to pack up and head back to the shop by 6am. Three hours, 40 miles, five breakfast burritos, and four cups of coffee later, we rolled into Otso and Wolf Tooth HQ. A little exhausted from the trip, but ready for the day and our next bikepacking overnighter.
