Okay, is a stem like this opened with a hex allen wrench??
Alright, here is my problem, I am working on a stem similar
to this but I don't think it is for a hex allen wrench to open up. It's really a circle rather than something with angles. The part to unscrew is not convex or concave as it might be in this picture, it is flat.
Without the fancy gold: it is this stem:
See that opening?? I don't think it's been stripped, I'm unsure of what would open it up.
I've looked it up on the net, I've got books. Maybe, I hope there is a simple answer and I will profess ignorance gladly then, but it'd save me a trip to the bicycle shop who by the way, I have supported numerous times this year already.
I can't figure out how to open it up. I've opened up many handlebar stems, with the hex allen wrenches or the older kind with a bolt to rotate with a crescent wrench.
It's an English Bike by the way too that I'm working on, cerca 1980. I can provide more backup if needed.
