As much as necessary, as little as possible: With the 1x drive, you have all the gears you really need. Brake levers with a small reach increase braking comfort for riders with smaller hands on smaller frame sizes (XXS, XS, and S). Marlin models in sizes XXS to S come with a curved top tube and lower standover height to make it easier for smaller riders to get on and off. Mounting options for racks and kickstands make it easy to attach practical accessories that turn your mountain bike into a sturdy commuter.
