I just buried the BRC Explorer I rode around for 8 years due to a metal failure in the headtube, as mentioned in
this thread. FYI, this frame used a 128mm axle length, 22mm stem bar (Specialized brand too) and a 26.6mm seatpost. The fork is a Tange 5F. You know, it was kind of timely because I wanted to get rid of a few bikes. But, inconvenient. And, curiously, the bottom bracket was completely pooched! After taking the cranks off I gave the spindle a spin and "crunch...grind". I think a bearing might have fractured or something. Who knows how long it was like that and how many extra watts that ate up while pedaling. Yeesh.
