Is 67 head tube angle good?

Most trail bikes have settled on a minute range of somewhere between 65 and 67 degrees. Downhill bikes will have angles anywhere from 62 to 64. And XC bikes and road bikes have steeper head tube angles from 67 to 73 degrees. The head tube length is also related to riding style.

What is more important stack or reach?

For a given reach, a greater stack puts you into a more upright riding position; your hands will be moved upwards and your body position will rise more towards the vertical.

How do you calculate bike 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.

What is BB drop?

Definition. BB Drop is the vertical distance between the centre of the bottom bracket, and the axles of the front and rear wheels. This is a fixed, static measurement. Once a bike is built up and has no rider on it, this doesn’t change.

What is trail in bike geometry?

Trail is best thought of as the tire patch “trailing” behind the steering axis. Fork offset for road bikes usually ranges from 40 to 55 mm, generating trail figures from 50 to 63 mm. 57mm of trail is considered by many to be an ideal combination of stability and agility.

What is a relaxed geometry bike?

As a general rule, a race bike will have a low stack and long reach, while a bike with a more relaxed geometry will have a higher stack height and shorter reach.

Why are MTB getting longer?

One of the ways frame designers have been able to grow reach without changing effective top tube lengths too much is through the use of steeper seat tube angles, which we’ll cover below. After declining for a number of years, trail bike chainstay lengths also got longer between 2018 and 2021.

What is slack in biking?

A “slack” angle is anywhere from 63 to 66 degrees. This means the fork of the bike is going to stick out farther, creating a more stable ride at high speeds, but also be slower handling.

What is a slacker head angle?

Head Tube Length & Angle The head tube angle is the angle of the head tube in relation to the ground. A “slack” angle is anywhere from 63 to 66 degrees. This means the fork of the bike is going to stick out farther, creating a more stable ride at high speeds, but also be slower handling.

How can I improve my bike stack?

Because your headtube is at an angle, putting spacers or a higher rise stem, not only raises the bars (stack) it also due to the angle brings them back closer to you (reach). Putting a longer stem on increase the reach, but also increases the stack (assuming positive angle stem)… going shorter does the opposite.

How far should saddle be from handlebars?

For a performance road position, the top of the handlebar should be about 5-6 cm below the mid-point of the saddle. 4. For a recreational road bike position, the top of the handlebar should be level with the mid-point of the saddle, or maybe a couple of centimetres below.
