1978 Raleigh Super Grand Prix, misc repairs
I have a 1978 Raleigh Super Grand Prix that was given to me recently. I've been refurbishing it for use as my beater bike, and I need some help.
I believe the frame was designed for the 700c wheels that I got it with. I've switched to a 27-inch wheelset (the old wheels were shot), and and they seem to fit alright. Even the brakes work fine after a slight pad adjustment. The thing is, I hate the brakes and want new ones.
What can I replace them with? The bike currently has Weinmann center-pulls, but I would prefer calipers. How do I make sure to get brakes for a 700c frame with 27-inch wheels? Or is that not something I need to be concerned about?
Also, my newsed (new to me, but used) rear wheel came with a five-speed freewheel. I swapped it for the six-speed one that came on the wheels I got with the bike. I've had to do a lot of derailleur adjusting to get the chain to work right. Is there anything else I need to do adjust to make the chain run smooth other than maybe add spacers to the hub/axle?
