When it comes to fitness training and peak performance, nothing is more detrimental to flying fast than carrying more weight than you need to. Which is why every Allegro is built with lightweight triple butted 6061 aluminum tubing. In fact, our aluminum Allegro frames shed 14 ounces over their steel Coda counterparts. We design comfort into the naturally stiffer ride by specifying large volume 32c tires, using similar geometry as our Codas and then adding a few millimeters to the wheelbase length for just a tad more compliance.
