The Rennen Inertia Training System "Project 187" is a revolutionary weight training system designed for BMX racers looking for that extra edge over the competition. Using a unique weighted wheel concept, the Rennen IT system helps make you faster by using resistance training during flat ground sprints. This additional wheel weight will make acceleration very difficult at first, but once switched back to your normal race setup you will immediately notice the difference in speed and acceleration. Tested and proven by Rennen's factory race team to benefit both uphill and downhill sprints with just a single setup on flat level ground. Wheel weight is approximately 6 lbs with 11 lbs of additional weight that can be added or subtracted to your preference. 16T cog included. Available in 20" mini to 24" pro cruiser sizes.
Note: Designed for flat ground sprints only. Not intended for use on the track.
For additional weights up to 35 lbs call for details. 1-888-888-DANS (3267)
