drilling bridge on seat stays for internal nutted brakes
Posted: Fri Oct 19, 2007 5:49 pm
Hi all,
Fitting Dual Pivot internal nutted brake calipers to an early 80's Tange DB steel frame in place of the old single pivot standard nut caliper.
I need to drill out the forward part part of the bridge out to take the internal nut. I don't have a right angle drill attachment, and the ones I have looked at (Bunnings and Supercheap Auto) are a liitle big to get into the space between the seat tube and the seat stays.
Any alternatives or recommendations to enlarge the hole in the bridge, but keeping the original diameter for the caliper bolt on the caliper side of the bridge?
