I built up my Cross Check 3 years ago to be a year round bomb proof SS commuter. My parts choices Chris King headset, ultegra bottom bracket, Surly flip flip hubs. So far, perfect. I am replacing the bearings in the hubs right now before winter sets in, they're getting a little crunchy. But that's all I've needed to do so far. I'm about to cross 6k mile mark on the bike.
