    Weinmann Concave rims vs. something else?

    I'm trying to replace the rims on my '72 Paramount. They came fairly damaged, with a bunch of nicks in the sides, like they'd been resting on something sharp in the back of a truck. The give up a good buzz when I use the brakes. They seem to be just basic weinmann box rims, for hooked bead tires.

    Anyway, I've got a pair of Weinmann concave rims in decent shape that I'm thinking of replacing them with. They've got eyelets and straight walls for un-hooked beads. Last I remember, it's hard as hell to get a tire on or off the things.

    My question is, are the concave rims of good enough quality to bother replacing the old ones? I'm hoping to use the bike as a tourer, so I'd like something decently strong. Or should I keep looking for something else? I've got fairly limited resources, so I'm hoping to use something I've already got. I'd also like to stick with roughly the same time period as the bike, 70s or early 80s.

    Oh, and they're both 27x1-1/4". I'd like to stick with those.

    Comments? Suggestions? Opinions?

    I remember these being marketed to the tourist with loaded pannier. I remember making a set of them but I don't remember having a hard time putting the tires on. But I do remember my park spookie wrench scratching the rims cause if you to put them inside the concave part, turn it, and scratching the low part of the concave. Rims that era? Don't remember but I remember Rigidas and Ambrosias if you want higher end (where or where can you get those?). I also remember MA40's I think.

    They're strong. When I was a teenager, I hit a car head on while riding my Dad's old Windsor Professional. The downtube buckled but the Weinmann concaves held up perfectly.

    Without the hooked edge for modern tires you will be even more limited (then the already limited 27" selection) to which tires you can use, plus limited to lower air pressures. It all depends on the tire and the rims, but generally 70-80 lbs is the max you can inflate a tire to on a non-hooked edge rim.

    Since you might be touring (with a loaded bike?) you might want to consider new rims. I've used Sun's CR18s for several wheel builds including a set for my '66 & '83 Paramounts. I've been very pleased with the durability and the classic looks. I usually inflate my tires to 110-120 lbs. My bikes are fully loaded all the time because I'm over 250lbs. At about $35 per rim, I believe they are reasonably priced for their quality.

    Here's a pic of the ones I used on my Super Sport. This is the polished 27" and they come with eyelets on the spoke holes.



    This is the 700c anodized version I used on the '83 Paramount.

    The clincher models are excellent wheels, so I'd double-check before abandoning the idea.
    I've had no problem with the clinchers, 27", and not with tire changing, either.
    Machin Shin is running a nice set on his tourer.

    If they're not clinchers, whew.

    I used them for a while and had no particular difficulty getting tires on or off. My main complaints with them were with the spoke wrench nicking them and that they were heavy. I ran fairly high tire pressures with good results.

    I'd recommend something more modern and lighter.

    Yeah, you know, the lack of a hooked edge bothers me more than anything else about the rims. I'm leaning towards something newer, hopefully something not too expensive. Thanks for the suggestion on the Sun rims, I haven't heard too much about them, I'll have to check out the company.

    Thanks for all the suggestions guys. I think the fact that I can't put more than 70psi in the tires makes me want to switch them out.

    They are nice rims. I haven't changed the tires out yet, so I don't know if they are hooked rims or not. I've been inflating them to 80 PSI. Just in case.

    You might be able to find some Wolber/Super Champion Model 58s; those are pretty nice.

    Looks more like a cardigan.

    I can get the 700c version of them (quite narrow section) up to 90 psi, but if they aren't seated just-so, they'll blow right off. I take it yours are a wider width, and can take something fatter than 25mm tires. If so, I'd hesitate to use them for a bike you'd actually be touring on. I have built up Weinmanns with a different shape, and a Sun Mistral, and I like both results. Slap some 1-1/4" Paselas on them, and you'll be floating down the road.
    The search for inner peace continues...

    I have eyelet concave 700's as stock equipment on my 80 Super Course. They apparently thought highly of them at the time, as it's a DB 531 framed bike. I have another non eyelet set that came off of a old school Giant Innova. Aside from the eyelets, I can't tell them apart performance wise. I say go for it. They're defintely not your average looking rim, and have deep sidewalls to cover multiple brake shoe sizes.,,,,BD
