Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Handling stability / Handlebar height

Read somewhere recently that front wheel sketchiness might be caused by having bars too high, resulting in weight being too far back? Anyone ever here of this or experience it?

Less weight over the front wheel the less 'sketchiness' you going to have, thats why you sit up and take all your weight off the front wheel when you ride no hands.

If you didn't sit up when taking your hands off the bars you'd better have a strong mid section.

Lower handlebar height probably does make the bike more stable because it'll lower the rider's center of gravity. What would you rather take a high speed turn on?...a Harley or a Sportbike?

I do know a shorter stem makes for a twitchy front end. Would raising the stem not affectively shorten the stem length due to the rake of the headtube?

Any riding position with a center of gravity much different from the bike's design will noticeably affect the bike's handling. Moving your weight too far back will take weight off the front wheel and making the steering less stable (except when you're going downhill).

I had to spend a minute picturing that, and yeah, you are right. Sorta fits in with what FormerBMX'er said. It'd have to be a pretty significant raising/lowering to change the feel, I'd think.

Lower center of gravity = better handling.

Examples; 1) watch a crit, everyone corners in the drops not on the hoods.

2) motorcycle designs, for high performance handling, are designed to provide a low center of gravity.

Now the difference in raising or loweringthe handlebars a few centimeters may be nominal, but ceterus peribus lower handlebars equal better stability.
