I have an old 20.5" Raleigh MT-20 bike from the early/mid-90's with all Altus C10 stuff on it. The bottom bracket is a Shimano BB-CS11 with the following markings on it:
BB-CS11 Shimano Japan via 68 R3 BC 1.37x24 Spindle: D-EL
the plastic cap is on the R side.
I am trying to find a replacement and can't figure out what's compatible. Two local bike shops have given me two different answers. I have found a Shimano UN52 and a UN72 online that have similar (or the same) specs, but not sure if they'll work, party because they have the plastic cap on the right side, partly because I can't find any information about this BB.

Hi Jim It is an english thread (1.37x24 tpi) with 68 mm BB shell. Are you sure about the "R3" logo? it might be 103 mm spindle lenght, anyway you can measure it. If the spindle is square tapered it's easy to find a replacement by Shimano, you only have to ask for "English thread (1.37x24 tpi) 68 mm BB shell and spindle lenght in millimeters" it certainly will fit.

Tourney BB in an Altus bike ... typical hidden down grade. Altus with the FC-CT92 or FC-CT91 crankset should have a BB-CT91 Bottom Bracket. The makings on it would have been YL116, that is a 116mm spindle with a 47.5mm chainline.

Thats interesting, the listing for a BB-CS11 with the D-EL designation is 127.5mm spindle but with the 47.5 chainline ... measure the spindle to be sure.

Matters not

They may both be right.
