modify seat stay bridge? safe?
Hello.
I have been riding a Bob Jackson Vigorelli with Reynolds 631 tubing for about 4 years now - wonderful bicycle. However, I sustained a cycling related injury on my road bike and would like to stay away from fixed gear riding in favor of going singlespeed. I currently do not have the money to purchase another bicycle and I would prefer to simply modify my current ride -- it rides like a dream but I dont have it in me to ride fixed again. Until I can build up a proper road bike again, this is what I'll ride.
The Vigorelli frame does not have a drilled seat stay bridge for a brake. I did, however, request they include fender mounts at the time of the build for poor weather/winter fixed gear training. The seat stay bridge has a drilling on the underside for fenders.
Would it be safe to drill this bridge for a rear brake even though there is already a drilling for a fender just below where the brake hole would be? Or should this simply not be attempted? There, of course, would still be steel in between the holes, but would this be enough to secure a rear brake and not risk cracking the seat stay bridge?
For what it is worth, I primarily use my front brake and I live in very flat terrain - no long descents, ever. I do not want to ride with a freewheel with only one brake in the event of this brake failing and not having a backup.
I appreciate your insight.
Thanks.

A fender mount sees A LOT less stress than a brake mount. So, just because that bridge has one mount, it doesn't mean it can handle a brake.
Without seeing any pictures, I'd have to guess that because bike wasn't designed to run a rear brake, the bridge shouldn't be drilled for it.
Have you seen the bolt on brake mounts they sell specifically for track bikes?
