Our patented ADR (Active Debris Remover) bearing protection is built into the new ALPHA Pulley Wheels as an essential tech feature to deliver the perfect balance between efficiency and durability.
The best-in-class protection - which ADR’s utilisation of a fully enclosing stainless-steel dust cover and a surrounding bladed-groove structure that dynamically extracts debris from the pulley wheel as it rotates - allows for the use of a light contact bearing seal to keep bearing drag as low as possible.
ADR has been extensively tested in the field and test lab; as seen here in our trusted “Washer”, where muddy water pressure tests the protection levels of different pulley wheel and seal designs.

When Thomas De Gendt stopped by our HQ, we asked him a few quick questions about waxed chains and race use.
From demanding gravel races like Unbound and The Traka, Thomas shares why he sees the benefit of a waxed chain: less dirt build-up, a cleaner drivetrain and reduced wear in tough conditions.
For our UFO products, the ultimate test is real-life performance. By working closely with athletes, we use their feedback to help develop and refine formulas for the conditions they face on the bike.
Question: waxed or oiled chain?
Question: Biggest advantage of a waxed chain?
Question: Last race on a waxed chain? Did you notice a difference?
