I have a Raleigh Nitro Mountain Bike that I want to convert from a 5 to a 7 speed freewheel. The rear drop-out spacing is 135mm.
Am I right in thinking that all I need to do is get a rear wheel that is 135mm with a 7 speed freewheel? (And obviously upgrade the shifter and rear derailleur.) Am I missing anything obvious?
Many thanks in advance.
