420’s are the best do-it-all wheels on the market and are strong enough for racing or training.  Now they are evern stronger becuause of the 3 spoke lacing groups result in consistent spoke tension and share the load equally for increased wheel durability. Responsive and smooth with a lightweight, 34mm deep aerodynamic profile. The 420 rim is the lightest deep section aluminum clincher rim in the world based on special technology design by Bill Shook, when it comes to wheels this man know what he is doining.  He has also imporved the braking surfase and cut the spoke cound down to save more weight and belive is our not they are stiffer.  The rim profile and low spoke count bladed spokes were selected to slice the wind and give you the ability to hold your high end cruising speed. Now with an improved braking surface. The ride is fast with great accelerating properties. They climb well and descend briskly. The rims and blades are tough enough for ‘cross and the deep profile sheds mud. The 420’s are the perfect choice for serious riders and racers.

In our opinion do not was your money on anything but American Classic wheels, we have been riding them for over 7 years with very few hitches! they stay true, one our guy's weighs aprox 200lbs and ride the Sprint 350's  year round and they stay true the whole season.
