Why no store-bought, boxed wheelsets?

Comp hub features alloy shell with steel axle, serviceable steel ball bearings and extra thick external seals to keep the gunk out and the grease in. Ritchey Aero OCR Rim features a special offset cross section that reduces wheel dish and increases strength plus has a ‘just right’ depth: deep enough to add strength, yet still able to use standard length presta valve stems. Includes skewer and rim strip. Shimano 8/9 speed compatible freehub body. One year warranty through Ritchey against defects in materials and workmanship. I also purchased the matching front wheel. So, why not buy a boxed wheelset? Why should I have, instead, purchased a wheelset from someone near me (assuming I could find someone who actually built wheels)? To summarize the responses so far: This wheel set is good price for very good wheels. Consider a boxed wheelset not as wheels to install on the bicycle and ride away. Consider it as a wheel set kit with spokes laced into the hub and rim. Some assembly required. Repack the bearings and adjust the cones. Adjusting the cones is complicated because the tension of the quick release quill when the wheel is installed changes the adjustment. Oil the nipples inside the rim so that the threads are lubricated and the nipple-rim interface is lubricated. True the wheel. Pluck the spokes and note large variations in pitch. These variations indicate uneven spoke tension that needs to be remedied. Increase the spoke tension to the optimum tension. Stress relieve the spokes. Equalize spoke tension. True the wheel. Quite daunting, is it not? The instrucions for accomplishing these tasks are in books and on the web. You probably do not want to do this yourself at this point, so take the wheels to a wheel builder with this list and have him do it. If the mechanic seems unwilling to do the job as outlined above, find one who will. -- Michael Press |

Consider it as a wheel set kit with spokes laced into the hub and rim. Some assembly required. unless they're the "boutique" branded wheels, in which case, they're ready to ride, no further work required. Repack the bearings and adjust the cones. Adjusting the cones is complicated because the tension of the quick release quill when the wheel is installed changes the adjustment. Oil the nipples inside the rim so that the threads are lubricated and the nipple-rim interface is lubricated. do not get excess oil on the rim. any that can contaminate the tube will weaken it leading to increased blow-out probability. True the wheel. Pluck the spokes and note large variations in pitch. These variations indicate uneven spoke tension that needs to be remedied. Increase the spoke tension to the optimum tension. using a tensiometer - do NOT go with the oft-quoted "tension as high as the rim can bear" misinformation. it does not increase the strength of the wheel and increases the propensity of the rim to taco. Stress relieve the spokes. Equalize spoke tension. True the wheel. Quite daunting, is it not? The instrucions for accomplishing these tasks are in books and on the web.

I figured they have been stressed relief as I gave the wheels a check before I rode on them by flexing using the pushing down method on the wheels with my weight and hands. I heard no popping or pinging sound, so I assumed they were stressed relief. No pinging indicates no spoke wind-up which doesn't necessarily mean they were stress relieved. I would stress relieve them anyway; it can't hurt. Sounds like you got a very good deal. I bought a NOS frame from Bensbikes a few years ago on eBay. Art Harris |

They were smooth, trued and stress relieved right out of the box. I installed the Ultegra 9sp cassette, made no derailleur adjustments and had no problems or even a hint of out of true. Here is the link: http://cgi.ebay.com/ws/eBayISAPI.dll...=7158760 928I was going to build my own, but when I saw this I thought I try them out.It would damn near cost me that in materials alone.FWIW-tom YMMV, I guess. We see a lot of Wheelsmith built wheels from kits from Security, a distributor and probably the largest 'kit' supplier for new bicycles. I always take the WS wheels and first stress relieve them, take parallel spokes and squeeze them hard, and I have always seen the WS wheels go way out of true. I have never seen a WS set of wheels be 'styressed' by me that haven't gone to hell. AND using my DT spoke tensionometer, they all are low tension, particularly the fronts, who may be built by the 'rookies'. AND, why they can't seem to line up the label on the hub on the valve hole amazes me. VERY small point but it's so easy to do.... |

I heard no popping or pinging sound, so I assumed they were stressed relief. If I did hear that pinging, I would have put them in my truing stand and check for runout. Taking windup out of spokes is not stress relieving. Your method unloads spokes and takes the windup out, same as dropping them gently on a padded surface, taking the windup out. But not 'stress relieving'. I've been riding on them just about everyday since receiving the wheels in early June. They are still true and as smooth as silk, I had to do nothing to them so far. I was going to check the grease in the hubs, but I can see grease still every so slightly oozing out. I guess there will always be doubters in this newsgroup who will try to find flaws with the wheels I purchased from Benscycle, but I'll to say I'm very pleased with the performance and what I paid for them, and that's what counts. Bencycles also sells the Dura Ace wheelset, with the Open Pro's in black,but they're $100.oo more. Benscycles didn't build these, did they? WS labels maean they were built by WS in Oregon. I'm more of a rider and like the Ultegra, not interested in paying anymore than I have too. The only thing I have that is Dura Ace is the downtube shifters and I'm using them with the Ultegra rear derailleur. Never missed a shift in 7 years. -tom |
