@Luniz82 I was trying to find the specific tube I used. All I remember is that at the time I bought the tube almost 2 years ago, it was the longest butted 34.9 mm tube I could find. That narrows it down to either .9-.6-.9 or .8-.5-.8
I appreciate the feedback on this. I rode this bike quite hard. I’m not sure what I should expect for how long a frame should last when ridden hard. It’s a 150mm fork. The head tube is quite short and the head angle is quite slack. 110mm and 63.5 degrees. I am going to remedy that on the next bike I build, but I would like to repair this one. What would you recommend to use for that? larger diameter? thicker wall?
