This is the most popular style of bike because it can be used for pretty much anything.
Trail bikes have more relaxed angles to give greater confidence when descending and kit that’s designed to deal with more punishment. They use shorter stems and wider handlebars to help improve control at speed, while tyres will have more aggressive tread.
Trail hardtails use strong frames matched to a fork of around 100 to 130mm travel, while full-suspension trail bikes will use between 130 and 150mm of travel at either end.
1x drivetrains are almost universal, offering a wide gear range with simpler maintenance and better performance. Trail bikes either use 29in or 650b wheels.
