Allegros are like racehorse commuters--tightly wound for performance with components from the road bike parts bin, just like their fast-rolling big-diameter 700c wheels.

The Allegros are the fastest street bikes available this side of a dedicated road racer. Road bike geometry meets flat handlebars in the Allegro, with a lightweight performance-tuned frame welded from hydro-formed 6061 aluminum.

But don’t think this means the Allegro is all seriousness. Yes, it’s almost brutally fast. And yes, it’s supremely practical. But when you roll along on an Allegro it’s so incredibly efficient, it’s so good at banking into corners and getting you there quickly, you can’t help but smile. Or wonder how the ride’s over so soon.
