New for 2012!

Rennen Design Group has been testing the concept of Inertia Training with various members of its factory team along with Greg Romero (Coach G) for the past year. We have proven that the concept helps make you faster by slowing you down (via G-Cog data) and once the rider adapts they can achieve faster times on their normal race setup.

The results you can achieve are amazing. This idea in a nutshell is the equivalent to a on the bike power squat. Its the most BMX sport specific resistance training that you can get. See for yourself (here) the reactions we got when showing the worlds best riders and coaches a sneak peek of the Rennen IT system

Add a new dimension to your sprint routine by stacking on plates to change the resistance of the sprint while riding your race gear ratio.

Inertia Wheel Sprint Training also offers something that no other form of resistance training can provide. From zero to max speed the sprint will feel very hard while you are accelerating this high inertia wheel. Once at a constant speed the IT wheel feels easier to pedal than a traditional wheel at the same speed. The result is that you get the benefits of a uphill and downhill sprint all on flat ground all using one setup. The Rennen IT system is intended for flat ground sprints (Do not try to ride this at the track!)

The Rennen IT wheel will be available with a rim attached and in the following sizes: 20-1.75, 20-1.5, 20-1-3/8, 20-1-1/8

Base weight of the wheel is ~6 lbs (2700g)

The IT wheel will come with 11 lbs (5000g) of weight and additional weight in 2 lb (900g) increments can be purchased directly through us. The total weight of the IT system can reach a whopping 34 lbs (15.5 kg)
