rear dropout spacing problem
Hi,
The measuring caliper shows just under 132mm for the rear axle dropout on my aluminum road bike frame. And since i at one point squeezed the frame on a 125mm rear hub (never rode it, but had it siting like that for a while before i got to know that it's a big nono for alu frames) i'm not sure if the 132mm is a shrunken 135mm spacing or if it's just a loose 130mm. What do you guys think? is it usual for a 130mm frame to have some "slack" on the dropouts, or do you think it's a bent 135mm?

I see! well, hopefully that's what it is.
About the frame, it's a bit of a strange one. It's a HEAD frame, but i can't seem to find any information about HEAD bikes whatsoever (almost like they don't manufacture them). And i got it for cheap a few years ago from a guy who ran a small bike shop and had i laying around. So all i know is that it's a fairly light race/road (?) frame made in "7005 lite alloy".

They're huge in the tennis world, have had some popularity in the ski market but never made much of a dent in the US bike market.
Got pics of bike?

I don't have any at the computer right now. But i would gladly post some pictures when it's finished. The project is mainly based on the frame that i stumbled on for cheap and a reynolds carbon fiber fork that i got at a 50% sale. And i'm using as many components as i can from an old beat up racer i got for free to use as a donor bike. So it's a "decent bike for a limited budget" type of build.

As posted above, odds are it was built that way to split the difference between 130 & 135. Rest assured that simply squeezing it to 126 wouldn't have bent the stays, nor does the amount of time you kept it there matter.
