I asked an earlier question regarding putting modern road wheels on my old steel frame.
After clarifying a few things the main issue to me is the number of gears on the freehub. (The freehub I'm considering takes an 8/9 speed and has a Shimano fitting). My bicycle is currently a 7-speed and uses a freewheel rather than a freehub.
So I think I have 2 options:
- Put an 8-speed cassette on the new wheel and increase the number of gears on my bike. Issues: I assume an 8-speed uses a narrower chain; will my front chainring work with it?
- Put on this 7-speed cassette which says it can work on an 8/9-speed hub with a set of spacer rings. Questions: how do I use the spacer rings? Do I need only one of each for the whole cassette of one for each sprocket? Will this allow the slightly wider chain I currently use on the 7-speed.
Which option would be the better choice?
A few points to consider:
- Shifters are friction, so no need to consider indexing but I am unsure whether they have the range for an 8-speed (but with a narrower chain maybe the range is the same, just with smaller movements between gears)
- My deraileur is actually a modern Shimano 8/9 speed already (as the old one broke). I have adjusted it to suit my 7-speed with the limiter screws.
