Choosing the right size bike

You should choose the size of your bike based on your height, as well as your build (arm span and leg length).

If you are between sizes, opting for the smaller size will give you a more comfortable position that makes it easier to tackle gravel trails.

Tyre sizes

Please be aware of the risk of tyres that are over 36mm.

Even if the clearance between the wheel and the fork and frame is enough for 40 mm tyres, there is a risk of you coming off your bike in the event that your shoe comes into contact with the front tyre. This can happen at low speeds on tight turns, and will depend on the size of the frame and how you've got your SPD cleats set up on your sole.
