Retro Newbie
Hello,

I found a old Muddy Fox explorer from 1988 into a trash bin.

I have start restoring it (removing stuck bottom bracket ....)

I have measure rear dropout and it 126 mm , if I m right.

I would like to fit a modern wheel (I have a brand new wheelset in stock).

Is it risky to stretch it to 135mm ?

Thanks for you help.
 
No, should be fine. Have a look at the Sheldon Brown 4x2 spreading technique. The most important bit is bending the dropouts so they are parallel afterwards. Do it a little at a time.

I would expect a 130mm rear though.
 
Thanks for you response, I will take some courage to stretch it. I fist need to finish my current project :D
