Hi all
I have a rebuilt 3-speed with a 127mm (Shim. UN54) b/bracket as per the recommendations for the replacement crankset (it came to me with caged bearings and loose cottered cranks)
Its slightly out of chainline, as the bike has a chaincase that's held by being sandwiched between the B/B driveside shell and the frame - this wasnt an issue at first but after a year the chain's got enough lateral wear that it vibrates loudly when I put some effort on as the whole assembly is 1mm or 2mm to the right of where it should be due to the extra thickness.
Does anyone know if you can get a 125mm or 126mm sealed-cartridge bottom bracket for 68mm shells and standard threading? I found some for 73mm shells but have only seen a YST threadless BB (which general reviews warn me off buying) for 68mm
Cheers
