Closely related to Giant XC and trail bikes, the ATX features the familiar flat-handlebar and 100mm suspension fork of a traditional XC mountain bike. A lightweight ALUXX aluminum frame, engineered with comfortable geometry for challenging terrain, adds to its rugged personality. The ATX also features size-specific wheel diameters-smaller size bikes use 26-inch wheels, while larger sizes use 27.5. This tailors the bike’s handling to every rider’s size and height. Powerful disc brake technology gives you confident handling no matter the weather or riding conditions. And integrated mounts let you easily add racks or fenders to suit your riding adventures.

SIZE GUIDE: MOUNTAIN
Getting the right fit can make a real difference to your whole riding experience, giving you a comfortable and efficient ride. To work out the right mountain bike frame size for you, all you need is your height and inside leg length. Once you’ve got these measurements, use the charts in the size guide tab to match yourself to the manufacturer’s recommended frame size. NOTE: This is a guide.

How do I measure my height?
With your shoes off, stand upright against a wall, with your shoulders back and legs together. Use a pencil to make a small mark on the wall above your head. Then measure from the floor to your mark in centimetres or feet and inches.
How do I measure my inside leg length?
With your shoes off, stand upright with your back against a wall. Place a book/ruler between your legs, level with your crotch. Then measure from the floor to the top of the book/ruler, in centimetres or feet inches.
How are mountain bikes sized?
Mountain bikes combine features of both road and mountain bikes and they can be sized in inches, centimetres or using a S/M/L system. The frame size is calculated by measuring the length of the seat tube, from the centre of the front chainring to the top of the tube (where the seat post inserts).
NOTE: Sizes can vary slightly between manufacturers.
I’m between sizes-which mountain bike size should I choose?
If your measurements suggest that two mountain bike sizes are suitable, then in the end it’s a personal choice but the rule of thumb is to choose the smaller size. That’s because it is possible to make a smaller mountain bike frame bigger, whereas if the frame itself is too big for you, it’s likely to be less comfortable and less efficient.
Are frame sizes different for women-specific mountain bikes?
Yes-for example, a medium women’s bike will be smaller than a medium men’s bike. However the sizing itself is calculated in the same way, so a 17″ men’s and women’s bike have the same frame size.
