JaeP 08-03-2005, 09:23 PM Both of my Paramounts thank you Mr. Hickey. Are the 112 bottom brackets the old fashion loose ball bearing types with the knuckle busting spanniers? Would a 110 modern cartridge bottom bracket work? Do they even make 112 cartridge bottom brackets? Dave Hickey 08-04-2005, 05:13 AM Both of my Paramounts thank you Mr. Hickey.

Do they even make 112 cartridge bottom brackets? Shimano used to sell UN-72 cartridge BB's in 112. I'm not sure if they still do. In answer to you your question, there were many cartridge BB's sold that will work with the 7400 cranks. Just make sure it's square tapered and not splined. I've never had a chainline problem going a mm or two either way |
