I searched, but found nothing to answer my question anywhere, perhaps because it is a non-issue:
I picked up a cheap 700c wheel with 135mm hub spacing for my road bike. I have the understanding that 135mm was a mountain bike spec, and 130mm is standard for road bikes. I am not worried about using the wheel in the frame. My question is, can I just buy any Shimano Hyperglide 7-speed freewheel, or do I need to get one with a particular overall width?
It's a late-80's (I believe, having trouble finding catalogs) Giant Kronos with all Shimano Exage Action components and Biopace chainrings. The decals look earlier than the 90s Kronoses which I can find.
