Jamis Allegro A3 Step-Over

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. The combination of road bike drivetrains, flat bar shifters, lightweight aluminum frame and carbon fork means you can Gran Fondo it on the weekend, then race through traffic during the week.

Aluminum When It Matters
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 Frame Design
Size Specific Design (SSD) is the Jamis design philosophy and technique used to create the best possible riding bike for each size rider. Rather than limiting frame size variations to just different length top, seat and head tubes, we take an all-inclusive look at each frame’s total configuration. Every SSD frame will also feature size-specific BB drop, rear center, fork offset/trail and SST technology.

Absolute Versatility
Every Allegro offers a full complement of eyelets and rack mounts to simplify installation of carriers and fenders. We even include bosses on the underside of the seatstays for installation of a ring lock. Ring locks are tremendously popular in Europe and will soon most assuredly be popular in the USA. A simple turn of the key immobilizes the rear wheel and prevents someone from riding off with your bike.

Stopping Power
Going elbow-to-door-handle in traffic with cars requires a reliable brakes. The Allegro Comp delivers with linear pull brakes, which are plenty powerful rain or shine. To make sure you’re in complete control even when grabbing a lot of lever for a surprise stop, we include power modulators on the front brake. This modulator absorbs excess lever pressure, assuring controlled braking performance.
