Gravel riding has been taken to new levels in the past years. What used to be a niche cycling event for the rebels and rule breakers has taken to the masses, with events that are packed with faces from all walks of cycling life, from the avid endurance athlete to the roadie, and everything in...

Gravel cycling is a bit of an enigma. While it's mostly new to the scene, it manages to evoke nostalgic feelings that we don't really get from modern road cycling these days. Between wool jerseys, steel frames with drop bars, and a sense of adventure that doesn't stop when the tarmac ends, it...

Eagle range on a drop bar bike? Now that's a party. The Apex Eagle rear derailleur quietly and quickly shifts across our 12-speed Eagle cassettes, while 1x-specific chain retention technology keeps the chain where it needs to be. It's the best of our road and mountain bike innovations in one...
