rear 27"wheel question
 

How would this wheel be for replacing an old Heliocomatic freewheel wheel on an 84 Trek 510? Would it be an upgrade? Price is so cheap. Let me know, thanks! http://aebike.com/page.cfm?action=de...=30&SKU=WE8691

Even cheaper

Either should work pretty well, but if I were buying one I would take it to a local bike shop to have them check the spoke tension and true of the wheel. They would be machine built, which isn't a bad thing, but the spoke tension is often not great on such wheels.

I have the same size wheels on my Schwinn Le Tour, Varsity, and I believe my Sprint. Same size I should say. I definitely need to find replacement wheels for my letour and my sprint.

Any suggestions?

73 Le Tour, 84 Varsity (I Believe) and a 90 Sprint.

they both are a great replacement.

The AEBike hub is 130 mm OLD so, assuming your Trek is 126 mm, you will have to force it in or cold set the frame.
