For Sale: Mavic cartridge BB. Lovely unit, wants the outer ends of the BB shell to be chamfered to match. Gives nice little amount of lateral adjustability. Fine condition. $75 shipped CONUS. For just a little more, might throw in a lovely but off-topic frameset with 1 - 1/4 headset and adapter to off-topic stem. But we don't mention anything except the qualified parts like the Mavic BB, eh?
Interesting trades considered.
Delivery to Westminster is quite feasible.
