Got an old pair of Campag wheels which are going on a rebuild bike. They came (from eBay) with a 6-speed freewheel attached. The teeth are the old-fashioned 'squared' sort i.e. they are rectangular in cross-section.
The bike will likely end up using friction shifters. I've read a bit about the benefits of using freewheels designed for indexed systems - Hyperglide etc. - with friction shifters. Apparently they are much smoother in shifting.
My question is: should I change out the freewheel for an indexed, twisty-tooth style one? They're pretty cheap and I would like the shifting to be as smooth as possible.
2nd question: how much does the brand of freewheel matter? If I get a 6-speed or 7-speed Sunrace (e.g. http://www.sjscycles.co.uk/sunrace-7-sp ... prod22242/
) would I have to get matching Sunrace from chainrings and chain?
