What to Compare Before Buying
- Bike weight: The stated limit is 15 kg, so compare your bike’s weight with that figure.
- Frame shape: This carrier is for narrow tube bike frames only, so frame shape is the main fit check.
- Roof bars: Check that your bars suit the stated maximum dimensions of 58 mm x 50 mm and the 45 mm thumb wheel opening.
- Mounting method: Decide whether the supplied U-bolts suit your roof bars or whether the optional T-bolt kit is needed.
Compatibility, Size and Fit
This carrier depends on three checks: the bike weight, the frame style and the roof bar dimensions. The carrier is described as suitable for narrow tube bike frames only, so it is not a broad fit-all option.
It also needs compatible roof bars. The stated thumb wheel opening is 45 mm, and the roof bar limit is given as 58 mm x 50 mm. If any of those figures do not match your vehicle setup, a different mounting option may be more appropriate.

Before You Decide
Confirm that your bike weighs no more than 15 kg and has a narrow tube frame. Then check that your roof bars match the stated mounting size and that you are happy with the included fixing method before choosing an offer.
