Any guidance on trimming a steer tube?
I have a NOS frame that I installed a headset on today and now need to sh orten the steer tube by ~ 1/2 inch.
Also, I have a headset spacer that requires the steer tube to have a flat spot milled into it. I hate to grind out the flat spot in the spacer sin ce it is a rare headset and would like to keep it as original as possible .
Any help is appreciated,
