has anyone spred the rear stays on an aluminum bike? i want to put an 8 speed nxus or alpine put the axle width is abut 5mm narrow :?
 
If you're only short by 5 mm (2.5 mm per side), all you have to do is pull your dropouts a little farther apart as you're mounting the wheel. This is easily done with the bike upside down. Just set the hub in place, with the axle nuts resting at the slot openings. while positioning yourself behind the bike, use your fingers to pull the stays apart, while using your thumbs to guide the axle into the slots. Once things are lined up, gravity takes over and the wheel fall right into place. You'll find it takes minimal effort to pull your stays far enough apart, to accomplish this.

It's okay to "flex" your stays apart, a bit, since aluminum will flex, and 2.5 mm per side is not enough to cause a permanent bend, which you don't want to do with aluminum. You see that whenever you remove the wheel again, your stays will spring back to their original positions.

If you don't trust this method, then don't do it, but I have 3 (soon to be 5) aluminum Electra's done this way, and 2 of them are 10 mm to narrow. And, if you look around the web, you'll see many other people with aluminum framed bikes that have upgraded to wider geared hubs. I've never heard about a single incident where someone had damaged their frame by doing this.
 
I flexed the rear on my OP Roller to fin in a nexus 3 and it took a little more than my thumbs to do it but it fit just fine. Not sure what the difference in width is from a 3 to an 8 though.

Spread those legs until you break them...then bend them back.



Gotta TIG? Roll Nickles

(im only serious))
 
Could you elaborate on how you spread the rear forks? I am going from a 50's single speed to a Nexus internal 7 speed with internal brake. Any help would be greatly appricated. Thanks.
