Try to remember I work on broken stuff every day at the bike shop, and I have the wholesale prices close at hand. I know a lesser wheel that costs more when I see one. I can get a bewildering array of packaged wheels for my customers, but I don't-- and frankly, my customers don't ask for them. I could build 20-spoke wheels too. They'd be as good or better than the packaged wheel equivalent, because I've been building strong wheels for a long time. And they'd weigh a little less and have a little less aero drag than good wheels with normal spoke counts. But those subtle/unmeasurable benefits would come along with unsubtle/ obvious shortcomings in durability and reliability. So I don't build wheels that suck, even though I could, and even though they'd cost less in materials and take me less time to build than wheels with adequate spoke counts. Take note of that: Low spoke count wheels cost less in materials and take less time to build. Do you think manufacturers are doing these things just for your increased performance? And why does a wheel that costs less to them cost more to you? If you don't think the term "snookered" applies here, you're probably not looking at the situation critically enough. Chalo |

Your last paragraph is true only if "packaged" low spoke count wheels were built with the same materials and in the same way as regular wheels, which they are not. I'm sure that the relatively heavy, proprietary rims used on the Ksyrium wheels are more expensive than, say, an Aerohead -- and the per-spoke price for those flat-bladed Zicral 7075 aluminum spokes is high -- a lot higher than mundane stainless steel spokes. I don't know whether the automated machinery takes longer to build a 20 spoke uber-wheel with Mavic's "Isopulse lacing design" or a 36 spoke ordinary wheel. If done by hand, though, it might be impossible to build a Ksyrium-like low spoke count wheel without some sort of press or ram to compress the rim while you wind up the spokes to the tension necessary to hold the wheel true. Or if you can't afford the ram, I suppose you could just use some glue. So you need to factor in glue time and cost. You also have to factor in the time for Isopulse lacing (including the time for figuring out what "Isopulse lacing" means.) -- Jay Beattie. |

I'm sure that the relatively heavy, proprietary rims used on the Ksyrium wheels are more expensive than, say, an Aerohead -- Why are you sure of that? Why would it be more expensive than for example a Chukker, which is much deeper and heavier than an Aerohead but costs a similar amount? and the per-spoke price for those flat-bladed Zicral 7075 aluminum spokes is high -- a lot higher than mundane stainless steel spokes. * I tell you this as a seasoned aerospace and high tech machinist: 7075 aluminum is easier to work than 300 series stainless, and it can be heat treated to maximum strength all at once rather than drawn and swaged to achieve cold worked strength in several steps. So why do you believe the cost to produce aluminum spokes is intrinsically higher than say, 14-15ga butted stainless steel spokes or their flat counterparts? Is it just because the retail price per replacement spoke is so many times more? Consider that the latter is probably unrelated to production cost. Chalo |

People are getting excellent use from low spoke count wheels that are not expensive. Fewer spokes = less aero drag, all other being equal. The earlier Nuvation (sp?) wheels broke hub flanges; I think that problem has been addressed, and those were the only really failure- prone LSC wheels I happen to know about. Those are pretty inexpensive wheels. I'm not totally in touch with brands and price points, since I "don't go there", but I hear reports of satisfied users of several brands of LSC prebuilts, up and down the price range. My cohort doesn't slam hundred-mile dirt road rides on Sunday as in days of yore; I know I wouldn't, and I'm sure their owners wouldn't use these LSC "road" wheels for that riding. Or, maybe they would, and there would be some most excellent beta testing going on g. If the LSC wheels require more maintenance, some riders, mostly in the "racer dude" population, are willing to deal with that for the perceived advantage. I wouldn't call that being "snookered". LSC, not the thing for utility use? No argument there. I have one set of LSC wheels, some old Shamals that I bought separately, used. The front obviously had some miles on it, the rear was near-new. Those are 16-spoke, F/R. I haven't put tons of miles on them but I did use the front quite a bit with no problems, when I was well over 200lbs. The rear was added later and I rode them as a set for awhile before I finally hit something hard enough to remind me to go back to using my usual handbuilts (Campy hub, Aerohead rims, 32/35h) in case I really smacked something and needed to replace a rim and/or spokes. IOW, you're preaching to the choir to some extent, at least in my case. Those Aeroheads, with 23mm tires mounted, mostly, have been as reliable as (for instance) my old 430g Ambrosio Synthesis Durex sew-up rims, speaking as a rough comparison. If I were riding lots of rough roads, I'd do as I did in the past, mostly with another Ambrosio rim, the Elite Durex and run fat tires with thick sidewalls. Those rims lasted until the sidewalls got ground thin from brake use and separated from the spoke bed. Why would I want to go to huge rims and tires? Is someone trying to snooker me? --D-y |
