The frame is built to be stronger than on other types of bicycles and is designed for the best possible ride over rough terrain. The geometry can be chosen to achieve optimal stability or agility.
The material is aluminium, the most widely used option. It is lighter than steel and sturdier than carbon fibre, and is used in the production of many types of bicycles, offering the best weight-to-price ratio.
This mountain bike pairs a KELLYS Alutec aluminium frame in size 14 (36 cm), recommended for riders 145–157 cm tall, with a lightweight 13.5 kg build in a lime-green finish. An SR-Suntour XCE28 fork with 100 mm of coil-spring travel smooths out the trail, while a 1×8 drivetrain with a MicroSHIFT derailleur and an 11–42T cassette keeps gearing simple and wide-ranging. Mechanical disc brakes provide reliable stopping power, and 26 × 2.10 WTB Nano tyres deliver confident grip.
