Subject: [CR]Application of flanged hubs


I lived and worked in the Princeton area from '77 into 98, and hung around quite a bit at Kopp's. It was after Swann's time there, but I met him when he returned for a visit.

Mr. Swann was not an engineer, but had undoubtedly forgotten more about bikes than I will ever know. Some of his statements undoubtedly reflected wisdom from the school of experience. Others, equally firmly expressed, were simply opinion dressed as fact and carried through the decades. Mr. Swann has passed on, and his colorfullness will be missed, but I don't think any one ever accused him of either doing or reading about credible experiments.

I hope I'm wrong.

>From Angel Garcia: Here is something I previously posted on th application of flanged hubs:

In the small accumulated pile of stuff I have I found some articles on wheelbuilding by Dick Swann. My old-timer friend says he worked at one time for Kopps in Princeton, NJ, as a wheelbuilder and that he was English(?). I guess some here would know him? Here are some of the things he said (material is undated):

1) .....resilient small flanged wheels used by stage race riders differ greatly from the tied, large flanged wheels favored by hill climbers.... 2)....the very object of using a large flange hub is to stiffen the wheel.... 3.....Circuit races (crits, Kermesses, etc.): on small tight courses with many corners, it is best to use a large flange hub to steady the bike in the many (often sharp) corners. Also, with the numerous accelerations that must occur on such courses this large front hub wheel prevent wheel whip (me: what is wheel whip?!) 4) ...Timetrialing: do use small hubs for lightness and halving wind resistance.... 5)...Hillclimbing: The front wheel has to be extra strong; in some events the rider is off the saddle with his weight on the front wheel for up top 75% of the distance... 6)....Sprinting: Large or medium size hubs... 7)....Paced racing: use largest flanged hubs available... 8)....Track timetrialing: small flange hubs.... 9)....Team pursuiting: "heavy" large flanged wheels

for each of these categories he has suggestions for spoke counts, spoke gauges, when wheels should be tied and soldered, etc.
