Borealis Bikes- CARBONDALE Rim!

COLORADO SPRINGS, CO- Borealis Bikes, maker of high-end carbon fat bikes and accessories, has just announced the release of their new CARBONDALE rim. Named after the amazing small town outside of Aspen, CO, the Carbondale rim represents multiple leaps forward in the evolution of fat bikes. Extreme stiffness, lightweight, and easy tubeless set up make the Carbondale rim an incredible upgrade to any fat bike out there. On to the details!

TUBELESS: The Carbondale rim makes the days of foam strips, sealant tape, blown off liters of Stan’s sealant and ringing ears a thing of the past. The rim is designed for a very tight fit between the bead and rim, with a large bead hook and lock to keep the tire in place, even at low pressures. It takes roughly 3-5 minutes for the average mechanic to set these rims up tubeless, and Borealis recommends using 45NRTH tires for this. Only a Stan’s tubeless valve and sealant tape such as Stan’s yellow spoke tape is needed, along with 60 grams of Stan’s sealant. The tires seat at roughly 22-25 PSI and will stay in place at standard fat bike riding pressures.

STIFFNESS: The CARBONDALE rim was designed for hard use, not just for getting a low number on the hanging scale. It is double walled construction, with a strong triangular shape and reinforced spoke bed. These are manufactured using the latest pressure-molded rim technology with a removable air bladder in between the 2 rim walls. The lateral stiffness is significantly higher than that of an aluminum rim and can be noticed immediately when ridden. The 85mm wide rim provides an excellent platform for both 4 and 5 inch tires.

WEIGHT: The 85mm wide double-walled CARBONDALE weighs 590 grams. This is pre-production weight, so final production weights may vary slightly. These rims, set up tubeless with 45NRTH Husker Du tires and Borealis hubs on a Borealis Yampa XX1 size large bike brought the weight to 21 pounds 8 ounces, with an extremely practical build.

AVAILABILITY: These rims are in final pre-production stage. Borealis is now taking pre-orders for the rims and is predicting they will begin shipping the first week of November. Interested parties can contact their local Borealis dealer or contact Borealis directly for pre-order information.
