I got a new set of tires mounted yesterday. On the way home I felt some feedback in the handlebars, almost like some vibration in the front wheel making the handlebars go slightly back and forth. Went from trailwings with 11k+ miles to new conti trail attacks.


Was it just the new tires? The crappy roads? The fact that I haven't ridden a lot this year and I forgot what it feels like?

It's the tires. The Conti Attack series are known to wobble around 40mph especially.

Good to know, it was about at that speed I noticed.

Hopefully something that goes away as they break in?

Nope. It's the nature of the tire. Tires designs are a balance between straight line stability and ease of changing direction, stability and nimbleness. The Road Attack was a little too nimble for my preference and I've read the Trail Attack is similar. It isn't dangerous and the tire does a fine job otherwise. Even at 40mph with the hands off the grips and the bar shaking like a paint mixer, the shiny side would stay up.

Just guessing here, but...I'd put Dyna Beads into the tires. They may stop the shake. With what you have invested in the tires, 5 ounces, $12, of Dyna Beads might be worthwhile. If not, you're not out much. They're easy to put into the tire, just kinda tedious to get them in. They will do no harm. They do work for balancing. They might work for this situation.

How they work...when the wheel is on a sprung suspension the heavier spot tends to be closer to the center of rotation (not the geometric center) and the lighter spot farther away. Centrifugal force will send the balancing beads to the farther-away spot and thereby balance the tire.

Even my Speed Queen washing machine has dynamic balancing beads:

I actually have dynabeads and all the stuff to put them in. Might be selling tho, so I don't know if its a good idea or not.

I barely could notice the feedback in the handlebars / doesn't seem to affect ride comfort or performance. They were brand new tho, so I babied it on that ride.

Check your tire pressures often when new. Over inflation could accentuate any wobble. Just a thought.
