i believe that this is a very useful thread and so i'll go first.

Haro Nyquist Two Frame- I used this frame for a year. it is a strong frame considering. I havent bent anything on it but it dents somewhat easily. it is like 5 pounds. what i hate about it- there is a indent for a sproket that could be 46 tooth. i am scarred to bend it there because it looks weak. also, i cant run small gearing and im rubbing my chain on the chain stay with 11-30 gearing. un-removable gyro tabs. The paint is very thick so it scrathes really easy
