The Record UD 10 speed titanium cassettes use the race proven Ultra-Drive system. Racers and enthusiasts are always looking to reduce weight without sacrificing performance. One way we've done this is replacing our steel-and-titanium sprocket set with an all-titanium one, now manufactured in the Ultra·Drive profile. Its tooth profile contributes to Records precise and smooth gear changing. Tested under all weather and race conditions at the Tour De France, the Record Ultra Drive system worked to perfection.
Please Note: The cassette lock-ring is included.
