Does a higher degree in Head Angle increase stability?(5 posts)

I'm waiting for some jokes but am talking about frame geometry.

Or is this the wrong forum??
Or is it offset??? no text!Grinder

Overall stability is controlled by every aspect of frame geometry. Typically, by increasing head tube angle and reducing trail, the frame will be more responsive in cornering. However, for an inexperienced rider, this may actually decrease their stability on the bike.

Hope this helps!!

so hard to ride no handed. Every other bike I ever had was easy but this thing just wanted to crash whenever I wanted to stretch. You would think that after 4000 miles I would have been able to handle the dang thing.

Now I'm looking into other, newer, low-end (< $700) roadbikes and am looking for the magic formula LOL!

What increases stability at speed is a greater (numerical) amount of TRAIL. This is defined as the length on the pavement from the horizontal intersections of a) the line running through the steer axis of the bike, and b) the line running vertically from the axle, down to thepavement.
If you only increse Rake, you will increse trail. You will also increase the vertical gravitational response through the bars, which will cause greater instability at low speeds.
If you decrease offset, you will increase trail, also to the detriment of low-speed stability.
So, the answer is yes and no. It depends on what speed you will be riding at. For a touring bike, you would not want a lot of trail. For a racing bike, you would want a lot.
