The Phil BB in question was installed correctly and ridden on a bike that only sees fair weather. The bearings wore prematurely and were crunchy and developed play in just under 1000 miles. Phil replaced the bearings under warrantee but I haven't used that BB since, so I don't know if the new bearings will last longer. But, considering the initial cost of the BB + the trouble have having to ship the BB back to Phil, I could have just as easily bought 5 other bottom brackets that probably would have each lasted many times longer.

My point is not to declare that Phil products are ****..they clearly are not. However the cult-like worship of Phil Wood products often clouds reality. They are not flawless and despite the fact that they are 5 times the cost of lesser components, they are not 5 times as durable or 5 times less likely to fail. 99.99% of the time, lesser components will work just as well and in some instances better. If you plan on touring the southern cone of South America on y our tandem, then Phil Hubs may be the best choice. But if all you do is ride your trendy fixie around town, you are kidding yourself if you think Phil Wood hubs offer any significant advantages over other hubs that are equivalent to the increased cost.
