So I got nailed by a car Monday night and am just now getting around to assessing the damage... The front fork on my bike is severely bent and I think will need to be replaced. I am going to get this done professionally as I do not want to mess with the headset on my own. Can anyone tell me the appropriate size steer tube for a 58cm frame? my rough measurement came out to about 6.25 inches... does that seem right? also, it's an older bike with a threaded stem, anyone have any advice on maybe converting it to a threadless? Ultimately, I think I will buy a new fork and bring that to the bike shop to have them make the switch. Any help would be much appreciated... thanks!
