ROCKBROS Suction Cup Bike Rack for Car Roof Top Sucker Bike Rack Quick Release Aluminium Alloy Bike Carrier with Sucker for 1 Bike

This is amazing would recommend to anyone !!

That’s an excellent product! I’m a cyclist and ride regularly 3 times a week about 40mils and long rides on weekends of at least 50/100 miles. I bought a new car and decided to get the rockbros as I don’t have a fixed bike rack on the new car (and won’t be getting one :) - and it worked greatly on my last weekend ride! I drove about about 120miles to and back the event at mostly freeway speeds of 60/65mph (did not go over 70mph. I installation was super easy just make sure you clean the mount location and I did follow instructions leaving the location a bit humid after I cleaned it (according to the manual leaving it bit wet helps) had absolutely no problem mounting my road bike on it and it was surprisingly easy to take it off the roff (to be honest a bit too easy as I expected it to be much harder to take it off) but it held firmly throughout the trip and gave me all the confidence I needed no problem! Again great product quality for the price and I’m very satisfied with it. Thanks!

This rack is FANTASTIC as long as it doesn't come loose or un-suction during a long ride... time will tell on that one. So far it seems very sturdy.. .with my bike on it I can pull on my handlebars and the entire car shakes which is great! The bike does sway a bit on turns and bumps but I guess that's to be expected. My only worry is that it sways too much? The way its designed it seems that each time it sways it might actually push the suction on one side down further! As one side pull up the other is pushed down so.... NOTE FOR PEOPLE WITH THRU AXEL WHEELS/FORKS - I have a 15mm x 115mm Thru axel measured at REI from post to end of threads and so I needed an adapter. When asking RockBros AND REI which measurement they are using they said the FULL length of the axel stem......... this is incorrect, the measurement is the DISTANCE between your forks or the Axel stem measurement NOT INCLUDING The threads. Needless to say my 15 x 115mm thru axel works with the 15mm x 100mm adapter. I went crazy trying to figure out if I needed a 115mm axel adapter but just decided to try out the 100mm. It obviously worked and now I can transport my bike!! Note: the manual is brief but it suggests getting the suction cups wet before mounting. This is actually a good idea and helps prevent leaks and makes the suction a tad better. You wouldn't think adding water to your suction cup would be a good idea lol...Wouldn't it make it slide? No it works well and since I suction using my read window for the fork I can actually see the bottom of the suction cups during the ride to make sure they look the same as when I started which they do.

I was actually sceptical about this system and how it would hold but it works fantastically and I have complete confidence in it now. I've even received a few compliments on the setup

Install is a bit to get used to. once you get familiar with it doesn't take to long. Only thing is its way easier to have it on the ground when putting the fork and axle through but not fully tight. Then remove plastic covers and immediately put on car position and tighten. I've Driven up to 110kms/hr on highway with light wind and going easy on turns and bumps. No issues. We'll see how long it lasts. Also wish the velcro strap for back tire could be something else. Would make me feel abit better but sturdy still. The caps for the axle are just pressure fit in the device and move when trying to fit fork on could have been threaded onto device to prevent this. Also sold separately to fit a specific thru axle. Like really making me pay another $15 for plastic circles. Good product if it lasts as it would be catastrophic if it fails
