The size is also not mentioned in the product description and it mentions all sizes so it is an easy assumption that it includes all sizes, especially considering the price, which is not the case. For 170+ AED / $40 for 2 small pieces of plastic bushes it is ridiculous. I really don't know why they should need to be purchased separately anyway, ROCKBROS should send a full set of adapters with the suction cup mounts.

The size is also not mentioned in the product description and it mentions all sizes so it is an easy assumption that it includes all sizes, especially considering the price, which is not the case.

Survived long downhill decents and curves. ### ⭐ NOT 15x110 *by A***0 on 26 June 2021* Ok...So I'm pretty much all done with RockBros period. Their 2 bike suction rack was a nightmarish mess. This is similar weird level lack of quality. Description on Amazon literally says 15x110. Description on the baggie the 2 pieces came in says 15x110. So how come when I install my boost 110mm fork on the rack, there's 10mm of slop left or right in the spacing? Seriously....I get that they want it to have a little bit of "give" to be able to more easily mount while you're holding a 30lb MTB over your car roof, but this amount of wiggle will let the bike slop around left and right and doesn't inspire any sort of confidence that this thing will hold up long term. ## Frequently Bought Together - ROCKBROS Suction Cup Bike Rack Adapter 9/12/15/20mm Diameter 100/110mm Axle Length for Car Roof Top Sucker Bike Rack - ROCKBROS Suction Cup Bike Rack for Car Roof Top Sucker Bike Rack Quick Release Aluminium Alloy Bike Carrier with Sucker for 1 Bike --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/457327082-suction-cup-bike-rack-adapter-9-12-15-20mm-diameter](https://www.desertcart.tn/products/457327082-suction-cup-bike-rack-adapter-9-12-15-20mm-diameter) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-18*
