This is false logic. There are at least 15 parts on your bike; by your policy we should expect catastrophic part failure once per year.

Because weight is now being stressed over anything else we, unfortunately, can expect at least one catastrophic failures per year.

Though I'm back to steel bikes I had a set of the top of the line Campy aluminum wheels. I did a local ride with a nice 12% climb and strong decent. That is a 40 mph drop. After I got back to town and was about a quarter mile from home a spoke broke on perfectly flat and what passes for smooth road around here. The rim distorted so much I had to carry the bike the remaining quarter mile. If this had happened on that decent... The wheel only had about 3-4,000 miles on it since new.


We like Campagnolo wheels generally (within the set of
'modern boxed wheels' they are well above average) but
consider for a moment that a wheel with 36 or 40 spokes may
usually be ridden home with one out but a wheel with 21
spokes usually cannot.

This doesn't make any product good or bad but it's a factor
you might consider when choosing a wheel for a particular
purpose (annual club TT vs 200mi ultra vs following Joerg up
a goatpath, etc)


I have decided that I will buy cyclocross wheels from now on. I can't tell any difference in the looks of the wheels so I suppose they only use larger diameter spokes. But that alone should increase the lifespan of an expensive wheel.


True CX wheels will use a wider rim, which may or may not be to your taste or tire profile. For your retro bike, just build a set of 32 spoke wheels on ordinary hubs. Use a mid-weight rim like a DT450 (also cheap) or maybe something more aero. 14/15 spokes with brass nipples. My fancy wheels are Dura Ace C35s which have been bomb-proof. Everything else is conventional 32 spoke wheels. I'd go 36 or 40 if I were building a touring wheel. Any high spoke count wheel with conventional spokes can tolerate a broken spoke. I have a spoke wrench on my key chain. If I break a spoke on my commuter, I just adjust the tension, ride home and throw in a new spoke.
