The CURT 18125 is designed for vehicles with factory roof racks and cargo baskets. Your vehicle must have a factory roof rack with a weight capacity that can support the cargo carrier plus the weight of your bikes. The product is rated for a maximum of 150 lbs., but you must never exceed your vehicle's factory roof rack weight limit. Check your vehicle's owner's manual for the roof rack weight rating before purchasing.
The CURT 18125 adapters support both 100 mm and 110 mm fork spacing. The adapters can be flipped to accommodate either spacing. You must verify your fork spacing before installation to ensure you use the correct orientation.
The CURT 18125 is compatible with 9 mm, 12 mm, and 15 mm bike axles. For 9 mm axles, use the included bushing with a groove and the quick release. For 12 mm axles, use the bushing without a groove and re-use your bike's axle. For 15 mm axles, no bushing is required and you must re-use your bike's axle.
The CURT 18125 includes: 2 quick release mechanisms, 2 tube spacers (12 mm), and 2 tie down straps. The quick releases are suitable only for 9 mm axles; for 12 mm and 15 mm axles, you must re-use your bike's original axle.
Yes. Step 1 of the installation requires you to remove any old fork mounts from the cargo basket if they are currently installed. This must be done before installing the replacement adapters.
After installing the quick release or axle through the bushing, wrap the included safety strap around the rear tire and cargo rack to secure the rear of the bike. Feed the end of the strap into the buckle and tighten it. This prevents the bike from shifting during transport.
For 9 mm axles, insert the bushing with the groove. For 12 mm axles, insert the bushing with no groove. For 15 mm axles, no bushing is required—proceed directly to inserting the axle.
The CURT 18125 cargo roof rack is rated for a maximum of 150 lbs. However, you must never exceed your vehicle's factory roof rack weight limit. The combined weight of the cargo carrier and all cargo must not exceed the lower of these two limits: 150 lbs. or your vehicle's OEM roof rack weight rating.
Yes. Periodic inspection of your product should be performed to ensure all hardware and components remain secure. This helps prevent damage to the product or vehicle during use.
The CURT 18125 works with vehicles that have a factory roof rack and cargo basket. Your roof rack must be rated to support the carrier plus bikes without exceeding its weight limit. Check your vehicle's owner's manual for roof rack capacity.
The CURT 18125 supports 100 mm or 110 mm fork spacing (adapters are flippable) and 9 mm, 12 mm, or 15 mm axles. Verify your fork spacing before installation.
