The brakes on my old Dawes are awful, so bought a pair of Shimano R650 dual pivot brakes from Ribble Cycles on line. They've arrived and look the bee's knees, but to fit I need to drill out the fixing hole in the steel frame to 8mm on the allen head side to accommodate the increased width of the restraining sleeved nut. Ribble assure me that the 1mm shoulder on the allen head will be safe enough to hold the bolt in place but I wonder whether I should avoid drilling the frame to 8mm and use a longer bolt with conventional 10mm head nut and washer.
Anyone any experience of drilling out the steel frame to use the modern allen head fixing on an old bike?
