Description
Transport your modern Boost-equipped MTB securely on your car roof rack with Rockbros Boost bike adapters (also called thru-axle hub adapters or fork adapters), the affordable, durable conversion pieces for quick-release or non-Boost roof racks to fit Boost front (15x110mm) and rear (12x148mm) thru-axle bikes. These aluminum adapters slide into your bike’s Boost hubs/fork ends, providing the correct axle spacing and secure mounting points for standard roof rack trays, fork mounts, or suction cup carriers (like Rockbros popular suction models). Available in pairs for front/rear or single sets, they feature precision-machined alloy construction with anti-scratch coatings or rubber inserts to protect your frame/fork, and they lock securely to prevent movement during drives. Compatible with most Rockbros roof racks, Thule, Yakima, or generic carriers that accept standard QR or 9/12/15/20mm adapters—simply swap in the Boost-specific ones for your bike. Lightweight (~50–100g per pair), easy to install without tools, and corrosion-resistant for all-weather use. More than just adapters—it’s your simple, budget-friendly solution for carrying Boost bikes (common on trail/enduro MTBs) on roof racks without buying a new carrier or risking damage.
