And? The context was a fear-mongering line of insinuation, questioning whether it had been tested enough and whether or not it would be abandoned in the future, leaving users SOL. Do you have a pretty good idea of what to expect from a bearing? Are they easily replaceable? Do you think that the bearings would be impossible to source if Trek EOL'd IsoSpeed? In this regard, his attempted BB30 sidetrack was actually a good example - the bearings used in BB30 were a common industrial bearing long before Cannondale developed the standard and they'd be readily available for current BB30 users even if Cannondale were to no longer support it; I would expect that it would be the same case if Trek were to discontinue IsoSpeed (but it's already been around for more than 5 years and, rather than walking it back, they've doubled down, so so much for that).
