I'm optomistic that some of you here can help me with the replacement of a rear wheel. I have a Mavic Ksyrium Equipe rear wheel that has developed rim splits along six of the spoke holes. Hence, I need to replace it. I've tried to be diligent in figuring out the best route to go, but am getting very mixed information. I've taken the wheel to four different bike shops to ask about replacing the wheel with something stronger. In all four shops they've been very surprised to see a wheel that has failed so badly. All four shops have also given me different information about wheels concering strength. Two of the shops say that the Mavic Ksyrium series is one of the strongest, and that includes the Equipe. One of those shops swears that the Mavic Ksyrium Elite is stronger than the Equipe. Another of the four shops says that the only way to go is Shimano Dura Ace 7800 hubs with Open Pro Mavic rims. The fourth shop says the Open Pro Mavic - Shimano combination is no stronger than the Mavic Ksyrium Elite. This fourth shop also says I can have the rim replaced and the wheel rebuilt. They think the current wheel is not typical and that there must have been some kind of defect for it to fail as it has. They also say they have to special order a rim from Mavic to get it and this could take some time. All four shops sell all of the brands mentioned. Frankly, I don't know who to believe. When I read reviews for RoadBike Review, I get mixed information as well. Is there any reliable source that evaluates these things independently? Do any of you have insight, recommendations, experience with the likes of this? All I want to do is get a reasonably decent set of wheels that perform well, let me run the 9 speed set up, and won't fail on me as the Equipe's did. I'm 215 lbs. Average about 17 to 18 mph on road rides, moderate amount of climbing, don't do any racing, but do long rides (3 - 4 hours).
