But, if everything is carefully attached and the vacuum mounts are not loose, there shouldn’t be any issues.

Normally, Talon will carry one bike only amd maximum load capacity is 45 pounds. However, people can use the other models for carrying two or three bikes. For instance, you can use Mini-Bomber to carry two bikes and the Bomber to carry three. But what if you own convertibles? Well, in that case, you can resort to KOMODO! Both situations sound incredibly awkward and kind of prone to scratching up the car if you slip just a bit. Also, if the suction begins to lose vacuum, the safety ring in the pump will extend outside to warn you. Once you see the indicator, you should re-pump it before you use it.Let me just elaborate a little bit. When you press a suction cup against your car’s surface, you push out the air inside it. It eliminates the pressure inside the suction cup and creates a vacuum. This vacuum seals the cup tightly and firmly holds on to the surface. Loading bikes is, of course, another primary concern. The SplitRail helps with this task by using tabs that keep the rear-wheel straps out of the way. It sounds minor, but in use it’s brilliant. The vacuum can mount on metal or glass surfaces and even fiber glasses and hold bikes of up to 45 lbs.

Rough sections of the dirt road caused no loss of suction. Plus, this second round of mounting the carrier and attaching the bicycle took 2 minutes — and I wasn’t at all rushing. Each suction cup uses a thumb-driven pump to evacuate air, and there are easily visible indicators to signify a safe level of vacuum negative pressure. Kupper Mounts Bike Carrier: First Impressions So, how to install it? Well, it’s easy. Wipe your roof carefully. There should be no dust or water on the surface.

The cups have a pull force of more than 210lbs, making your bike as safe as it can be while on the road. Now, you may ask, wouldn’t the cup slide? As a matter of fact, no. the cup doesn’t slide because the friction created by both the cup and surface keeps it from sliding. But to work like this, you have to take care of few things first. Don’t get disheartened. They’re not tedious at all. Don’t forget to clean the surface too. If it’s dirty or has any dust on it, the suction cup will not adhere to it properly.

Speaking of the load… there are three options available to you. If you want to carry only one bike at a time, you can. Just use the Single-bike version. If you need to haul two or three bikes at once, just go with the Two-bike and Three-bike versions, respectively. There is no set time length on how long it can hold. It will depend on where you are attaching it, the weight of the bikes, and the vacuum’s condition. But, as long as everything is in good condition, you shouldn’t worry about safety.Another highlight of the Mini Bomber is its small size. When it’s not needed, it can easily be stashed in most cars. Before each use, clean the vacuum cups with a sponge or soft cloth. Clean them with mild dish soap and water. The Aerodynamic frame isn’t there for aesthetics only. It helps control the wind resistance. Not only that. The frame also minimizes the amount of noise. As a result, you get a smooth and comfortable driving experience. VACUUM MOUNTED TECHNOLOGY: IMT vacuum mount bike carrier system uses a 10-inch suction cup for the fork mount and a 6-inch cup for rear wheel. Each suction cup uses durable UV and weather resistant concave rubber pad so that they can be attached to flat and cured surfaces
