I have an older steel frame thats lugged. its about 17 yrs old. anyway the guy i got it from trimmed the headtube down at the top and bottom maybe 1/4 inch each so the headset was lower. he raced on it for years after. i am building a single speed commuter trainer with it. should i have any worries about the strength etc. its is a high end race frame so it was made well.
