Part of me cringes when I see cable stops and guides angle-grinded off a frame. Then the other part of me thinks at least the frame is going to be rode a lot more. This video is a great guide for anyone who wants to hack the life out of a road frame and turn it into a conversion. Check out Sopron Fixie for the second installment anyday now.
Personally, I’d keep it as is and just make it fixed but that’s the purest in me.
