Hoping for a bit of guidance re the BB on my 2012 Expert SL3 please.
I bought the bike at the beginning of the year but, due to our fantastic British weather, have only used it over the last couple of months or so. It's done 2,500kms max.
Over the last couple of weeks a loud clicking has developed in the BB; it's not a creak, but a definite click once per rotation of the the cranks.
I took it back to LBS last week and they stripped it down, greased the bearings (apparently there was virtually none) and put it all back together. They assured me the bearings were fine; perfectly smooth with no grinding whatsoever.
Rode it Friday and all seemed fine, and then rode again Saturday and the clicking is back. As the noise has reappeared after only 175kms it is clearly not due to a lack of grease on the bearings. It's really only evident when under power, so climbing mainly and, more so, when climbing out of the saddle.
Am I right in thinking that, on this model, Specialized don't use a "true" BB30 in that there are Delrin cups that house the bearings?
I don't really know where to go with this; I'm told the bearings are fine, everything is tightened to the correct torque and yet the problem is still, painfully, obvious
Anybody got experience of this issue?
