CeramicSpeed OSPW RS ALPHA TEAM Logo — Shimano Dura-Ace/Ultegra Di2 (9250/8150)

The hand-built OSPW system the pro peloton actually races, dressed in the bold TEAM Edition logo and engineered for Shimano Dura-Ace R9250 and Ultegra R8150 Di2. The OSPW RS ALPHA TEAM Logo replaces the stock pulleys and cage with the same ceramic-bearing, ALPHA Disc system CeramicSpeed-sponsored WorldTour teams race on — so your Di2 bike rolls quieter, lasts longer, and frees up the watts most riders leave on the table.

Why riders choose OSPW RS ALPHA TEAM Logo

Oversized 13/19 ALPHA Disc pulleys with composite tooth profile. Stock 11T pulleys force the chain through tight bends that bleed watts and chew through chains. The two-piece ALPHA Disc — composite narrow-wide teeth on a solid aluminium backing — reduces chain articulation and runs noticeably quieter, so you save measurable wattage at threshold and your chain lasts visibly longer between replacements.

Patented ADR technology bearing protection. Standard derailleur pulley bearings die fast under wet rides and pressure-washing because debris gets straight to the seal. ADR's anchored dust cover plus bladed groove actively extracts grit while you ride — so the bearings keep spinning silent through winter base miles and hose-downs that would kill a stock pulley in one season.

Reinforced cage tuned for Shimano Di2 shift dynamics. Generic aftermarket cages flex under hard sprints and disrupt Di2 shift timing. The reinforced ALPHA cage stays rigid through full-power efforts and is geometry-matched to R9250/R8150, so your shifting stays crisp from the first interval to the final attack of a group ride.

Bold TEAM Edition logo — the look the pros race. The oversized TEAM logo is the same finish ridden by CeramicSpeed-sponsored WorldTour squads. Standard OSPW logos are subtle by design; this one tells everyone in the bunch what's hanging off your derailleur.

Plug-and-play install in under 15 minutes. No chain length change, no derailleur recalibration — bolts straight onto your existing R9250/R8150 derailleur with the supplied tools. Fit it the night before your A-race without any drivetrain anxiety.

Hand-built in Denmark, 2-year warranty, 60,000 km service interval.
