FUN=FITNESS, FITNESS=FUN
Musically speaking, Allegro means quick and lively. Which exactly characterizes the spirit of our Allegros: fitness bikes that are lively, quick, and seriously fun to ride. Our Allegros blend the speed and efficiency of a road bike with the heads up riding position many people prefer.

LIGHTWEIGHT & PRECISION FEEL
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.

- Size Specific Design Triple-butted 6061 aluminum frame with fast back rear triangle
- Hi-Ten straight blade unicrown with flat mount disc brake mounts
- Double wall alloy rims, 32H, alloy hubs
- Shimano Shimano EZ-Fire Plus, 21-speed
- Forged alloy crankset with chainguard
- Shimano RD-TY300 rear and Shimano FD-TY510 top swing front derailleurs
- Promax TX-121 linear-pull brakes with front power modulator and Shimano levers
- Jamis Touring saddle with SL cover
