We won't do it for you, you do it yourself and break your own frame (highly unlikely, but this is your deal). It's a Hozan tool made only for this job. One bike shop in 600 has one. It hooks onto the rear dropouts and spreads 'em with an all-thread screw, a little at a time. You avoid the grunt-and-sudden huge give that sometimes happens with cruder methods. But if you have only cruder methods at your disposal, here is---not a rock solid formula, but something to go by, sorta: If the chainstays are normal not heat treated CrMo (QB), you'll have to spread them about 35 to 40mm to effect a 5mm cold-setted diff. The way to do this Hozan-free might be to rig some barriers that don't allow you to pull past that. The H-free technique is Feet on inside of left dropout, hands pulling on right dropout. Like rowing a boat. Then reparallelize the dropouts. There's a tool for this, too, and any bike shop has it. If yours doesn't, run! G As one who has all of the aforementioned tools (and the particularly effective Park FFS-2) at his disposal, but who lacks the experience to use them wisely, I offer, again, the advice to go to a framebuilder or wise old LBS sage to get this work done.

RE: [RBW] Re: Quickbeam/Simpleone and Rohloff hub
That seems like a big adjustment to me--maybe Riv could tell you for sure wheather it'd be safe or even adjust one for you at point of purchase. If it were me, I'd look for frames spaced to fit the hub, if the hub is central to the goals you have for the bike build...I'd think there would be quite a few options among the 29/singlespeed frames out there!

RE: [RBW] Re: Quickbeam/Simpleone and Rohloff hub
Sheldon has an article on this: Ideally, the frame spacing should exactly match the hub spacing. This makes for easiest wheel replacement. In practice, however, there's a fair amount of latitude in fit. In fact, when the first 130 mm 8-speed hubs were introduced, they had locknuts with beveled sides, so that you could spring apart the rear triangle of a frame made for the then-standard 126 mm spacing. In general, you can safely go up one size in spacing this way, just springing the frame apart. I can't give you an absolute guarantee that this won't cause damage, but the odds are very much in your favor. If, however, you want to do it right, and your frame is steel, cold setting is the better way to go. If you're going more than one size, say from 120 to 130, or from 126 to 135, you should definitely cold set the frame. Sounds like you can do it from 120mm to 135mm. But I've never done it. -Original Message- From: rbw-owners-bunch@googlegroups.com [mailto:rbw-owners-bu...@googlegroups.com] On Behalf Of James Warren Sent: Wednesday, December 01, 2010 6:03 PM To: rbw-owners-bunch@googlegroups.com Subject: Re: [RBW] Re: Quickbeam/Simpleone and Rohloff hub I too would love to hear an answer to that question, since if it is wise, I'm pretty sure I'll do it to mine. -Original Message- From: Scott G. sco...@primax.com Sent: Dec 1, 2010 11:26 AM To: RBW Owners Bunch rbw-owners-bunch@googlegroups.com Subject: [RBW] Re: Quickbeam/Simpleone and Rohloff hub Has anyone respaced a frame from 120mm to 135mm ?

Re: [RBW] Re: Quickbeam/Simpleone and Rohloff hub
Alex doesn't subscribe to this list. But I do know that Alex emailed Grant and asked him his opinion about spreading the QB to 135 and Grant's answer was basically: don't do it. Which isn't surprising. If I were in Grant's shoes, I'd say the same thing. But Alex did it. And it was fine. I've done 126 -135 on at least 3 frames with no issues. If it were me, I'd do it -- or rather -- have a good frame builder do it -- without a second thought.
