SRAM Red New Cassette Noise Check.mov

Curious about how much quieter the new SRAM Red cassette was versus the original? So were we, so we mounted the new one and the original to a Parlee Z5 road bike with Mavic Ksyrium wheels and filmed them back to back in different segments of the gear range. The rest of the group is brand new SRAM Red with less than 50 miles on it. Look for a long term review on Bikerumor.com in the near future.
