OK so I have a Peugeot Galibier bike that consists of a Reynolds 301 steel frame.
A while back the original derailer gave up the ghost while riding, bending the rear-wheel spokes in the process. I was told it wasn't worth re-truing the rear wheel so I bought a cheapo Raleigh wheel from the LBS. I also bought a new 7-speed freewheel and Shimano derailer which I managed to install myself (using the original chain) and has been working great for about a year now.
The bike is nice to ride but I wouldn't mind upgrading the wheelset to a lighter and better set that would help with climbs and longer tours. I have in mind the Mavic Aksium.
I know this wheelset, along with many others use the modern dropout spacing of 130mm. I am pretty sure my bike is has 126mm spacing. Being a steel frame I am fairly confident i can just squeeze a 130mm wheel in there but my concern is the cassette size and chain.
I am under the impression that an 8-speed cassette uses a narrower chain. Would this work with my original crankset and friction shifters? i would rather stick with a 7-speed. Is it possible to find a semi-decent road 7-speed shimano cassette to fit on a Mavic Aksium and still use the slightly wider chain?
Any advice greatly appreciated....
Would this fulfill my need?

- Wheels are definitely 700c - I know this having previously replaced the rear wheel and buying new tyres & tubes.
- I would like to move away from the freewheel system to a freehub/cassette system. The idea is that I want to put a semi-decent set of road wheels on it. Mavic Aksium seems a good choice. This has a dropout spacing of 130mm. My bike has 126mm.
- I would like to avoid cold-setting (bending) my rear dropout if I can. Sheldon says it should be possible but there may be a few issues.
- Derailleur is modern so should hopefully take whatever chain is used.
- Friction shifters mean no worries about indexing.
- I would like to stick to a 7-speed cassette. Reasons: I doubt my shifters can do more than 7 (bike was originally a 6-speed); I assume this will help maintain chain compatibility between front chainrings and cassette. Am I wrong? Would the 7-speed cassette linked above need a spacer or would it just work out-the-box?
At the moment it seems like it should be OK. Maybe I should just bite the bullet and buy the wheelset and work to get it to fit....! Might help to borrow a friend's modern 700c 130mm hub wheel to see if that fits first though.
