The Masi Coltello is an amazing machine- a pure bred track frameset with a need for going really, really fast. The geometry is designed for steep tracks and immediate responses to rider input- the high bottom bracket is perfect for steep banked tracks so that you don't smack a pedal when deep in the turns or while maneuvering through the field.
The aluminum tubing used on the frame is plenty aero and even more importantly incredibly stiff. The rectangular chainstays provide massive stiffness for sprinting power with zero flex. The aero, teardropped shape of the seat stays provides stiffness and is aero enough to not slow you down when off the front in clean air. With the large aero shaped downtube and seat tube, the entire frame is slippery enough to be efficient in the wind when the smallest of margins can be the difference between first and second.
Another frame feature that aids the Coltello's dominance of the velodrome is the shaped top tube with the groove that runs the entire length of the tube top and bottom. This shaping helps the top tube resist the massive forces riders place on a frame when sprinting out of the saddle- especially when using steel or oversized carbon sprint bars. We also use an aluminum steer tube on the carbon leg fork to further minimize flex in the front of the frame- let's face it, flex means power loss and power loss is a bad thing in track racing.
What do all these design features mean? It means that the frames are incredibly stiff and aero enough to be ridden at the highest levels of the sport... all with a price that actually leaves you with enough money to actually afford some great race wheels and a few entry fees. And for all the riders looking for an urban fixed gear frame with more stiffness for aggressive riding, the Coltello will deliver more than just a little style with all that stiffness.
So if you're looking for a quality aluminum track frameset that can beat the super expensive carbon framesets to the finish line, or an urban frameset that will stand up to all the abuse you can possibly apply to the pedals... the Coltello is the answer to your search.
