I spread the dropouts on my 1978 trek 510 using to two X 4 fours clamped at the brake and chainstay bridge to keep them from being stressed Then used an althread Bolt with wing nuts to spread the dropout same amount On each side. I did it a little bit At any time over Several weeks.
I did go past the 130 up to 135 due to the spring back factor. Alignment was perfect. ________________________________ From: [email protected] <[email protected]> on behalf of Roy Summer <[email protected]> Sent: Thursday, January 1, 2026 9:09 PM To: RBW Owners Bunch <[email protected]> Subject: Re: [RBW] Tinkering time If you have a set of dropout alignment tools, you can carefully spread the rear from 126 to 130. Put the alignment tools in the drop outs (all the way back; take out any adjuster screws) and slowly pull apart. Make sure you pull evenly and keep the dropouts aligned. Test with a correctly spaced wheel or hub and measure as you go. Work slowly and carefully, keeping the dropouts aligned. Do not go more than 130. I did this with a 1987 Schwinn Super Sport originally spaced at 126 and now run a 1x8 drivetrain and a 130mm hub with no issues. Standard brakes will work fine. It will not increase the useable tire width as you are not spreading the stays far enough or wide enough at the top or by the bottom bracket to make a difference. And, as a final caveat, remember that Peugeots are French threaded bottom brackets and steerer tubes. Parts are available (not from me) if you search.

I'd love to find some 650b wheels for it, but the rear spacing (126mm) has made that more complicated.

It's down time like this that always gets me thinking about new bikes or tinkering with the ones I have. I have been riding two bikes exclusively for the last four years. The bulk of it going to my Clem followed by my Gus. The bike that has fascinated me since it's introduction has been The Roaduno. The minimalist drivetrain coupled with the relatively light weight frame just sounded like it would be a whole lot of fun here in the flatlands of Toledo, Ohio. But I really could not justify the purchase. I decided instead to resurrect my 2001 Trek 6700 MTB, my first mountain bike. Riv content to follow. The Trek sports a MUSA aluminum frame and has now been converted to a rigid single speed. It now weighs under 23 lbs. It has been a bit of a revelation. I have enjoyed it so much that I decided to convert the 2 x 7 Gus to a 2 x 1. It is fantastic! The 38 x 20 gear is perfect for the local singletrack - where Gus shines. The 24 x 20 low gear is a bail out only that might be low enough for me to navigate other hillier trails not far from home. It turns out that in my retirement wrenching on bikes is almost as fun a riding them.:) Link to photo album here: https://photos.app.goo.gl/NuFpEHG6LECnYmKV7 Oh yes, had a mishap but no harm done to body or bike.
