specialized m4 frame, a small dent from the left bar side hitting it when I flew off the rollers again!!! D'Oh! I feel it a bit with my hand, probably bent in about .3mm (guesstimate) and the patch size is like 1 cm^2 right by the cable there.

Anything that I should be concerned about with this paperthin aluminum? how do frames handle stress with dents in top tube? I heard its nothing serious


Woof the roller pro...not

geez....actually I have a small dent in my m4 frame on the top tube-about an inch long and bent in just alittle- and I have been riding it for a month and it has not crushed. Of course I am 135 and until someone pays for a new bike I have to deal with it.

Good question I would like to know what others think.

I was ambushed by two dogs while on about mile 29 of my first ride on a new bike, it's aluminum. Really sucked. My skin grew back but the frame still has a good sized dent in the left side of the top tube from the bars as well. The LBS said it was nothing to worry about. It worried me a for a while. I guess it just sucked most of all because it was new and the dent makes it look bad. But, I do not think about it much any longer. And, I have not noticed any problems at all I can attribute to the dent.

Lets go see. . . it's got 8376.4 miles on it now.

Keep riding, try not to think about it, but you will and after a while you won't.

I've seen frames break at the seat tube and bottom bracket, the chainstays and BB, but never along the top tube. It doesn't get stressed much, either by road vibrations or heavy pedaling, so the dent won't develope into a crack.

The tubing is so stiff, it's surely impossible to pull out by rolling or suction, like a dent in a car. So ya just gotta live with it. I've been riding a dented top tube for 15 years, still rides fine.
