FABBRI GRINGO 300 mm mounting cable extensions, pair Genuine FABBRI accessory for GRINGO rear spare-wheel-mounted bike and ski carriers. These 300 mm extensions supplement the "Universal System" mounting cables when the spare wheel is too large for the standard cables provided. Sold in pairs. Description The patented "Universal System" mounting mechanism fits all rear-mounted spare wheels. However, for wheels exceeding a certain size—particularly on 4x4s and pickup trucks with wide or large-diameter tires—the standard cables do not allow for secure mounting. These extensions lengthen the cables, ensuring the carrier structure is properly secured. This 300 mm length is designed for spare wheels that yield a value between 89 and 95 according to the FABBRI calculation method. Which length should you choose? FABBRI provides a calculation method based solely on the dimensions marked on the sidewall of the spare tire. Note the markings—for example, 225/70 R16—where 225 is the width in millimeters, 70 is the aspect ratio, and 16 is the rim diameter in inches. Then, add up three lengths (in millimeters) and divide the total by 10:

Rim diameter converted to millimeters: 16 x 25.4 = 406.4
Sidewall height: 225 x 70 ÷ 100 = 157.5
Tire width: 225
Total: 406.4 + 157.5 + 225 = 788.9; divided by 10 = 78.9, or 79 after rounding Match the rounded result against the FABBRI chart:
Up to 81: the cables supplied with the bike carrier are sufficient; no extension needed
82 to 88: 250 mm extensions, Ref. 6950270
89 to 95: 300 mm extensions, Ref. 6950271
96 and above: 400 mm extensions, Ref. 6950272 The result is a calculated figure, not a length to be measured directly on the vehicle. The calculation is based on the spare wheel actually mounted on the rear, with the tire inflated. If your tire has inch-based markings (e.g., 31x10.50 R15), this calculation does not apply; please contact us with the exact tire specifications. Specifications

Manufacturer part number: 6950271
Length: 300 mm

GRINGO BICI bike carrier, Ref. 6950251
GRINGO SKI ski carrier, Ref. 6950250 The length is selected based on the calculation result, not the vehicle model. Two vehicles of the same make may require different lengths if their spare tires differ. Tips
Perform the calculation before ordering, using the spare tire actually mounted on the vehicle.
Do not confuse these extensions (part numbers 69502xx) with the frame attachment cables (part numbers 62017xx), which secure the bike to the arms rather than the structure to the wheel.
Check the tightness before every trip, just as you would with the original cables. FAQ Do these extensions replace the original cables? No, they complement them. The cables supplied with the bike carrier remain in place. How do I know if I need them? By performing the calculation above using the markings on your spare tire. How many pieces are included? It is sold as a pair. Are they suitable for the GRINGO SKI? Yes, the spare wheel mounting is identical on both models.
