Subject: [CR]More on Weinmann Concave Rims

Dear folks:

These rims changed over the years, in makeup as well as in alloys used and in country of manufacture.. Earliest versions had eyelets, were high polished, and made in Belgium. Later versions were non-eyeleted (is that a word?), a satin-to-dull finish (particle blasted?) and made in the USA.

My comments do not address their relative strength and I think Super Champion 58s are a superior rim, but having said that, I, like Fred, in the 1970s used these rims a lot on my bikes (those also used alot in those days!) and received good service from them.

I think Joseph B-Z is confusing the Weinmann Concave rims with the less expensive Weinmann rims that resemble the current Velocity Twin Hollow parts.

In any event, I had the true Weinmann Concave rims on my tandem on my tandem and they definitely had eyelets. Also, they struck me as both stiffer and having a harder surface than the Super Champion 58s.

My wife an I put thousands of miles on those rims, loading up the bike with both front and rear panniers. We also put thousands of miles of Super Champion 58s, when we switched from 27" to 700c. In my experience, the Weinmann was the more reliable rim.

The is no denying, though, that some spoke wrenches simply will not work with the Concave profile. I will also concede that the Model 58s were easier to clean. Whether the Model 58s were actually more aerodynamic - in practice on a built up bicycle - is debatable.

Parenthetically, this is what I mean by loaded: http://new.photos.yahoo.com/fred_rednor/album/576460762322385988/photo/294928803253892364/2
