-Ash- said:Hey guys,
I have been trying to do a bit of research myself, but I'm honestly still pretty confused and a bit of an idiot!
I want to buy a new budget (£100-200) wheelset for my bike, but I'm unsure what would work with my bike frame (Ronson Atomic X, Reynolds 531), 7 speed cassette and Bontrager race lite 700 x 23 tires. The wheelset currently on the bike state 'Campagnolo Record'. For context I mainly use the bike for commuting back and forth to work in the city (24 km total a day x 5 days a week).
Any advice would be absolutely brilliant. Thank all!
NICE BIKE ...
[INDENT]BUT, the frame's rear spacing is only 126mm ...
AND, most of the contemporary wheelsets will have rear wheels spaced for 130mm rear dropout spacing ...
So, you have three options ...
Learn to rebuild the wheels, yourself, where you de-tension & re-tension all of the spokes & then re-true the wheels ...
OR, respace your rear dropouts to 130mm so that they will accommodate an off-the-peg wheelset & sell the old wheels for about £100 +/- on eBay ...
OR, remove the 4mm (?) spacer from a Shimano (accept NO SUBSTITUTES) Road hub on an off-the-peg wheelset to make it fit into a 126mm rear droput AND shorten the axle by 4mm AND THEN re-dish the wheel.

The rear dropouts on a STEEL FRAMES can be re-spaced on an ad hoc basis each time you insert a rear wheel designed for a 130mm frame ... the shifting probably will not be as good and there will be greater wear on the rear derailleur's pulleys ...
[INDENT][INDENT]Ideally, you will re-space the rear frame's dropouts to 130mm (it's easier to do than many people think) for the "new" wheelset:
[INDENT]To re-space a steel frame, first remove the rear wheel & measure the space between dropouts so you will a reference ...
While standing behind the bike -- WITH one hand on each dropout & your hands near your chest -- exert whatever you feel is about 5 lbs of force outward.
Measure the change.
[INDENT]It won't be that much if anything!
[/INDENT]
REPEAT until the space between the rear dropouts is 130mm.
[INDENT][INDENT]If you spread each side simultaneously then you should not need to worry about centering. If you do one side at a time, then you will may have to do a lot of tweaking to get the dropouts evenly centered.

You now need to square the rear derailleur's hanger ...
[INDENT]I sandwich the droputs with some scraps of plywood & tweak the droputs with about 3 lbs. of force (steel is softer than most people realize) to make them parallel to the bike's center plane.
Assess & tweak ... ensure that the derailleur hanger is vertical, too!
[/INDENT]
Part 1 takes about 5 minutes-or-less ... Part 2 takes a few more minutes.
[/INDENT][/INDENT]
The cog spacing on an 8-speed Shimano/SRAM Cassette is essentially equivalent to that found on a 7-seed Freewheel, so that's the best option ...
[INDENT]BTW, You will probably need to adjust your rear derailleur's high-low stops after you get almost any replacement wheel.
