CeramicSpeed OSPW RS ALPHA v2 TEAM Silver, SRAM Red D1/E1, Force D1

"What Our Gearhead® Experts Are Saying:""The ALPHA v2 TEAM is what I recommend when a rider wants the OSPW RS platform and is riding in conditions where bearing longevity actually matters. The ADR technology is genuinely impressive — the dust cover and bladed groove system work together to keep debris out in a way that standard seals just don't match. The solid disc pulley is a real-world upgrade, too. No spokes means nothing gets caught mid-ride.""Dirt, grit, and road spray do not stop a ride — but they do find their way into bearings over time. The CeramicSpeed OSPW RS ALPHA v2 TEAM is built around the premise that they shouldn't. Patented ADR technology combines a dust cover anchored in a groove within the pulley wheel with a bladed groove structure that actively extracts debris as the wheel rotates, keeping contamination out without adding drag. The ALPHA Disc pulley reinforces that argument with a two-piece construction — a composite narrow-wide tooth profile for wear resistance and noise reduction paired with a solid aluminium disc that eliminates the gaps where trail debris finds a foothold. The reinforced RS cage and customizable spring tension round out a system that performs as cleanly on wet roads as it does in dry conditions, and the oversized Team Edition logo marks it as the top of the ALPHA lineup."
