Avid B7 Triad Direct Drive Kit
New from Avid Racing Concepts is this Triad Direct Drive Kit which allows stock racers to remove the entire clutch assembly for conditions where the driver feels having less rotating mass and zero slip except from the differential is beneficial. Avid claim this system is the lightest direct drive unit available today coming in at 6.45g with a 72t or 2.62g with no spur. Also available as a Basics Version, which does not include any spurs, this is for the racers who already have Triad spurs. The full kit includes the most popular gears for stock racing.
