gearbox seals
One common type of oil seal is the lip seal, which features a flexible lip that makes contact with the rotating shaft to create a tight seal. Lip seals are often used in automotive engines, gearboxes, and industrial pumps due to their effectiveness in preventing oil leaks. Another popular option is the mechanical seal, which uses a rotating element to maintain constant contact with the shaft, ensuring a reliable seal even at high speeds and pressures.

3. Roof-Mounted Carriers While less common for RVs, these carriers can be an option if you are using a trailer with a flat roof. They require lifting the bikes to the roof, which can be challenging, especially with heavier mountain bikes. However, roof-mounted carriers do offer the advantage of keeping your bikes out of harm's way.
