Front mechs are the Cinderella of any drivetrain, but never has an easy shifting life been so affordable.

Front mechs are the Cinderella of any drivetrain, but never has an easy shifting life been so affordable.

New XT's lighter cage brings it to within 25g of XTR, while steel cages ensure a longer lifespan. Broader linkage means burly chain bullying, and they've even nibbled a bit off the back corner for extra tyre clearance. Limiter screws are angled for easy access, it comes in every top mount/ low mount/E type you could want, and it uses a universal shimmed fit so a new bike doesn't mean a new derailleur every time. All for £25? Just buy one!

Guy started filling his brain with cycle stats and steaming up bike shop windows back in 1980. He worked the other side of those windows from '89 while getting a degree in “describing broken things covered in mud" (archaeology). Dug historical holes in the ground through the early '90s, then became a pro bike tester in '97. Guy has ridden thousands of bikes and even more components the world over since then and can remember them all in vivid, haunting detail. Can't remember where the car keys are, though.
