How do you measure a bike for stack and reach?

Reach measurement. First measure distance of the head tube top middle from a wall behind (or in front) of the bicycle, then the bottom bracket distance from the same wall. Subtract larger from the smaller measurement and that gives the reach.

Does stack height affect reach?

Take two identical bikes, then make the head tube of one bike taller, so it has a higher stack height. This demonstrates how reach measurements are affected by stack height. When comparing reach between bikes remember the one with the higher stack height will feel longer than its reach figure would suggest.

Which is more important stack or reach?

reach is more important, because you will have to compromise less on stem length to dial in fit, but if your goal is less spacers for your current fit, then you’ll want to maximize stack.

What is frame stack on a bicycle?

Stack is the vertical height between the bottom bracket centre and the top of the centre of the head tube.

Is reach more important than top tube length?

This number is useful for identifying how long a bike will feel while in a seated position. Reach is newer way to measure a bike’s length. So Reach measures your cockpit anytime you’re standing and Effective Top Tube measures your cockpit only while seated with your saddle at a specific height.

How can I increase my bike reach?

A bike’s reach is determined by the frame and you cannot change it. However, you can artificially increase the reach by purchasing wider or longer handlebars. This will force you to sit further forward while you bike, which is effectively the same thing as buying a bike with a longer reach.

Does bike reach include stem?

We’ll look at some of the reasons for these design differences between Road and Mountain Bikes in a follow-up post, but if you want some clues in the meantime, consider that Stack and Reach measurements do not include cockpit components such as stems and handlebars.

What is Bicycle reach?

Reach is the horizontal distance from the centre of the bottom bracket to the middle of the head tube.

How do you use stack and reach?

Stack The vertical distance from the centre of the bottom bracket to the central point at the top of the head tube. Reach The horizontal distance from the centre of the bottom bracket to the central point at the top of the head tube.

What is my stack and reach?

Stack is the vertical distance from the centre of the bottom bracket to the mid point at the head tube. Reach is the horizontal distance from the centre of the bottom bracket to the middle of the head tube.

How do you determine stack and reach?

What is bicycle frame stack and reach?

Bicycle frame stack: how high is the top of the head tube from the bottom bracket. 1.2. What is “reach”? Reach is horizontal distance from the (middle of the) bottom bracket to (middle of) the top of the head tube. Picture 2 says it all. Bicycle frame reach: how far is the head tube from the bottom bracket.

What is stackstack and reach?

Stack and reach are the only really reliable frame size measurements. No matter what type of frame is considered (road, MTB, trekking…). 1. Explanation of the terms “stack and reach” 1.1. What is “stack”? Stack is (watch out now! ): vertical distance from the (middle of the) bottom bracket, to the top edge of the head tube.

How do you calculate the stack of a bicycle frame?

Subtract the bottom bracket height from the top tube height and that give the frame’s stack. Pictures 4a and 4b show the procedure. It is important that the bicycle is vertical! In the example from pictures above, stack is: 870 – 305 mm = 565 mm.

What is the stack and reach of a 51cm frame?

For example, a 51cm Cervelo S2 has a stack (Y) of 52.2cm (top of head tube is 52.2cm above the bottom bracket) and a reach (X) of 39.4cm (middle of head tube is 39.4cm in front of the bottom bracket). Why are a frame’s stack and reach potentially helpful numbers?
