Connect Air (Altangle x SeaSucker Collaboration)

No. The vacuum cups are made from a non-marking, soft rubber that is designed to adhere securely to smooth, non-porous surfaces like paint, glass, and fiberglass without leaving residue or causing scratches.

The vacuum mounts require a smooth, non-porous surface to create an airtight seal. It will not work on textured, matte, or heavily curved surfaces, as these prevent the vacuum from holding properly.

Each of the three vacuum cups features a 120 lb pull strength, providing a total of 360 lbs of holding power. This is more than sufficient to keep the stand stable while you perform maintenance or cleaning on your bicycle.

The Altangle clamp is designed to be versatile, but it works best on standard frame tubes. If you have an unconventional frame shape, such as a very wide aero tube or an e-bike with a massive downtube, you may want to verify the clamp's opening capacity before purchasing.

While the vacuum mounts are incredibly strong, they are designed for active use rather than permanent mounting. You should check the vacuum pressure periodically if it remains attached for extended periods, and it is best practice to remove and store it inside when not in use.

SeaSucker mounts feature a built-in indicator. If the pump plunger starts to extend, it indicates a loss of vacuum pressure, allowing you to easily re-pump the cup to restore the seal.
