What size road bike is best for me?

Choosing the correct frame size is a crucial component of getting the most out of your road bike. It's not just about comfort: when a road bike fits properly, it's more efficient, easier to handle and better at transferring your power to the road.

Fine-tune your fit

Now that you've identified the frame size that fits your dimensions, a Trek retailer can fine-tune your fit with small adjustments and helpful accessories. These adjustments will be related to the bike's geometry, so understanding the following elements of road bike geometry will help you to find the perfect fit for the way you ride.

Trek Road Bike Sizing Standover

Standover height

Standover height is the distance between the ground and the top of the top tube. It's important to have a bit of clearance between you and the top tube in order to easily dismount the bike and comfortably place your feet on the ground when necessary. To ensure proper standover clearance, make sure that your inseam measurement fits the frame size of your bike.

Trek Road Bike Sizing Reach

Reach

Reach describes the horizontal distance from the centre of the bottom bracket to the centre of the head tube, and is not affected by seat tube angle. A longer reach will result in a more stretched-out position, while a shorter reach allows the rider to sit more upright. Handlebar reach can be adjusted by swapping the bike's stem.

Trek Road Bike Sizing Stack

Stack

Stack is the vertical distance between the centre of the bottom bracket and the centre of the head tube. It indicates how tall the front of the frame is. Taller stack provides a more relaxed pedalling position, while a shorter stack allows flexible riders to get low and aero. Headset spacers are the easiest way to adjust stack.
