Similar to the Super Record cassette but made with 3 fewer titanium cogs. The last pair of three sprockets is mounted on a frame with a new structure that increases their rigidity. 3 nickel-chrome steel and 3 titanium cogs on 2 light alloy carriers for incredible weight and stiffness with 5 separate nickel-chrome steel cogs. 11 speed cassettes have different tooth profiles and shift timing for increased performance. 11 speed specific light alloy lockring is included. 183 grams (11-23).
I've been riding a Campy Record 12-25 for a number of years, and decided it was time to give knees a break and change to the 12-27. Because the increased size of the cogs meant a few extra grams, I decided to splurge and go for the Record cassette with it's three Ti cogs. My last Record 11 cassette has about 7,000 miles on it an still runs fine (just make sure you don't let your chain wear out), so I wasn't worried about the Ti Cog durability. As a bonus, I didn't even bother lengthening the chain, I just installed it on the wheel and tweaked the rear derailleur just a bit. Double bonus was a new Strava PR without trying!
