I've got two old Raleigh Sports from 1966. One used to be my dad's, and I ride it often. The other was my mom's, and is basically my spare-parts bike. You'd think I would have noticed this before, but it just came to my attention that my rider has mismatched rims. The rear is the Raleigh pattern rim, if that's what you call it, with the dip in the rim profile to accomodate rod brakes (though like most Sports mine has sidepull calipers.) The front is a plain steel rim, no dip. On my mom's bike, both the front and rear rims are the Raleigh pattern, although again it has sidepulls.
What gives? Doesn't really matter, I'm just curious. I thought that all Sports used the Raleigh pattern rims. I'm pretty sure the non-matching front is original. Maybe the men's (or would you say "gent's?) models used different rims for front and rear while the women's model didn't. Or is this a case where the good folks at Nottingham just threw on a different rim because they were short on parts, or what? Now that I've noticed, I may switch wheels so they match, although I suppose it would be more correct to leave them as-is.
