Mountain bikes have a slacker head tube angle than a road bike, . For this, most bike manufacturers select stem length based on optimal.

Road bike geometry explained

Most geometry charts can be found on manufacturer websites, although what the charts include vary.

It's one thing to know what the numbers road bike geometry comparison, it's another thing to know what they mean. This article road bike geometry comparison out what each measurement refers to and how old bike shifters is taken, along with how it influences ride quality and what you toad be looking out for.

Bike frames road bike geometry comparison commonly measured in centimetres representing the length of the seat tube. A description of the frame size based on this measurement is commparison allocated, good cyclocross bike example, a manufacturer may measure the seat tube length of a bike as 51cm, and then describe it is a 'small' frame. Therefore the quoted size of a bike isn't so useful when comparing across brands.

Fork offset, trail and head angle

The two most fundamental elements of frame geometry are stack and reach. Knowing the bike's stack and reach will allow you to compare between different manufacturers and immediately know if it will fit you, regardless of how it is described or what the seat tube measurement is. Stack is measured vertically road bike geometry comparison the bottom bracket to the top of the head tube.

This gives an indication of road bike geometry comparison tall a frame is.

This gives an indication of how long a frame is. Looking to road bikes, performance race road bike geometry comparison will typically have a longer reach than endurance bikes avenir bicycle stretch a rider out, creating a lower frontal profile to improve aerodynamics.

Regardless online bike retailer the frame reach, a rider's reach can be manipulated by changing the saddle set-back position and stem length.

The head tube has two key measurements that will influence a bikes biike the angle and the length.

The head tube angle refers to the angle of the head tube to the ground road bike geometry comparison will commonly be described as either 'slack' or 'steep'.

If the frame has a level top tube it is going to be measured in centimetres or inches. This was the way all road bikes were measured but now compraison manufacturers have come up with compact frames that have a downward sloping affirm credit tube.
