If you know you have the extra horsepower, you know you need one of the Cro-mo drivers. The heat treated cro-mo driver maximizes the lock up and ensures a positive drive with only adding a few extra grams.
The Speedline Killer Buzz Cro-mo driver even comes pre-loaded with precision sealed bearings so it is the easiest swap you can imagine. Instant power transfer engagement.
Same spline pattern to accept Shimano® compatible cogs.
