Hub size too big for fork?
hi i recently was lucky enough to get a 1967? Schwinn mens beachcruiser. Rims toast so i bought spiffy new blue ones. The old tire size was 26x1.75 so that is the rim size i bought. The back rim fits fine but the front hub is too narrow for the fork********** Why???? What did i do wrong? How did i buy wrong thing and how do i fix .i.e. replace hub in rim? Bend fork??? Dang i thought i had it right the back one looks so great.

Did you get a 2.125" (cruiser) rim for a middleweight (1.75", also will take a 1.95" tire)?
If you can take it back and get the middleweight rim or use it on s 2.125" fork and get another correct one.
I wouldn't cold set the front for the wrong rim, I've had both ends cold set down to 1.75 on my 1995 I was told by the shop? (why it won't take S-2s anymore) although the rims will take 2.125"
At least that's what his dad who used to run the bike shop said, that he did it.

Pictures would help. Schwinn didn't build cruiser bikes that early? The first bike they had with the cruiser name was abour 1980. They did build bikes that had cantilever frames though. Schwinn in that age didn't use 26 x 1.75 tires/wheels they used their own special sized 26 x 1 3/4 tireswheels which are not the same. I think pictures and a serial number would answer my questions and I could help you more. Roger

Measure.
Front hub width is one of the more reliable specified dimensions in the whole bike biz.
If you bought fairly new stuff, odds are the front hub should be for a 100 mm fork width.
there are some older/rarer stuff that’s narrower, but AFAIK none that’s wider.
Measure the inside width of your fork, measure the same dimension on your hub. Post your result. That’ll give us a better chance to judge if it’s hub or fork that’s off the norm, and perhaps suggest a fix.

First off please say you didn't trash the old wheels! I have run across front wheels with widths less than 100mm, which is the norm as some have said, and they were older 26x1 3/8. It's hard to say if your particular bike used Schwinn's proprietary wheels that is 26x1 3/4 or possibly 26x1 3/8 also popular on English style bikes. Something bought new in a shop should be for a modern cruiser unless yours is not a modern cruiser. The older Schwinn Racer, Speedster, and Collegiate were Schwinn's 26x1 3/8 and had a narrower fork. You might call it a cruiser by looks but it might be a horse of a different color. Check the old rims for any stamping to find out if they are indeed modern or not.
