132.5mm dropout spacing with a 130mm hub AFTER it has already been used with a 135mm hub
Short answer: Don't worry about it!
Steel is inherently a springy material and you will find the dropouts spring back to their original location once the wheel is removed.
In order to permanently re-set the dropout width, you need to bend the steel past its elastic limit. You can look up &quot;cold setting&quot; by Sheldon Brown or whoever you like if you're interested.
