Review? From

Shimano Sora performance

Sora has always had a slightly agricultural feel about it — gear changes tend to need positive force and aren’t quite as smooth as the more refined road cycling options in Shimano’s stable — however, that’s also its most endearing quality.

Sora is most often fitted to aluminium bikes around £700 to £800 and at this price point people tend to want something that works securely, all-year-round, and are happy to forego a little refinement in exchange for reassuring function. To that end, Sora delivers.

In fact, calling it ‘agricultural’ is a little harsh — ‘utilitarian’ would be fairer. It simply works. Rear gear changes might not swoosh quite so imperceptibly as Ultegra, but we’ve rarely — if ever — found ourselves cursing a misbehaving Sora rear derailleur. Similarly, all Shimano’s front derailleurs work very assuredly, and the Sora version is no exception. It’s also a very receptive system for home mechanics to work on.

Sora’s not all perfect, though. Those unexceptional-looking brakes are unexceptional in performance too. A swap to improved aftermarket brake blocks certainly helps, but fresh out the box we’d prefer the supposedly lesser Claris brakes.
