Cog size with old Dura Ace mech....
Guys,
Does anyone know if an old 7400 Dura Ace rear mech will accomodate a 7 speed cassette with a 28 largest cog? It's part of a retro build project, my wheels currently have a 12 (or 13) - 21 HG cassette and I wanted to swap to a larger range for hill climbing; would I be safer sticking to a 12-23?? Regards Dave |

Regards Dave No, it will handle a 28 just fine and dandy. Do this sort of thing all the time with 13 and 14-28 freewheels. |
