|bend rear triangle||chumbly|

|Hi, I've got 120mm spacing in my 20 year old frame. I want to make a single speed cross/commuter w/ it. I could go w/ a 120mm flip flop suzie hub or a 135mm surly 1x1 hub. If I go w/ the 135mm i may end up putting it on a crosscheck down the road. Therefore I'd like to bend the frame out 15mm. Is this ok to do? Can I just pull the dropouts apart untill they bend out to the 135mm spacing?

|The stays can be moved outward 7.5mm on each side, but it is recommended this be done by a shop/builder with a frame alignment table. This ensures the stays are adjusted equally to maintain proper centering of the read wheel. I would not recommend doing this yourself. |

|the Crosscheck is designed to work with 130 spaced hubs, too (the rear spacing on that frame is 132.5). Going from 120 to 135 on an old frame seems a bit much. I'd just go with the 120 spaced hub and save up a bit more money for something like the Gunnar Street Dog (cool frame -- 120 rear spacing). Or if you do buy the Surley you could always buy a new axel and space out the 120 hub.
|just use the 120mm hub||club|

|if you spread the stays that much, you'll have to dick around with the BB to get a straight chain line. Just get an old 120mm threaded rear freewheel hub and use that, it's the same threading as a track hub, you can use a track cog or a 1-sp. freewheel on it just fine. Bet your LBS will give you one outa the junk parts bin. Just say NO to boutique singlespeed hubs, they are a scam. You can use a q/r, you don't need a nutted axle to hold the wheel tight, just use a quality STEEL q/r skewer, not a weightweenie one with aluminum faces. Use LocTite 242 if you use the track cog, it will stay on, I guarantee it, without a lock ring. I got 4 fixers set up using the above advise and have no problems with pulling wheels or spinning track cogs. 120 to 135 is too much to spread the stays.|

|but I think loctite 271 is the one we want, no?
