Santa Cruz Chameleon with a wedge type EBB. Having trouble rotating the EBB to adjust the chain. Just stripped it and found it full of mud. Instinct tells me to copaslip both the wedge faces and the outer round surface where it meets the frame. Is there any reason why I shouldn't ?
So one no and one yes. 🙄 Part of the problem is that the two 5mm hex holes are a little worn. I can get it to move a bit by putting a 5mm hex key in one or other of them, but it feels like if I apply enough force to turn it, it will round the holes first. I could do with a sort of angle grinder type peg spanner to get a bit more grip and leverage.
Well, I've lost my copaslip, so that solves that dilemma. I think I may have found a legitimate use for WD40 though. It helped everything slide in to place and adjust, but as it has no long term lubricating properties, it won't prevent the wedge from locking the BB in place.
