Max. cog - Tiagra R. Derailleur
Hi, all. I've a touring bike with a 28-38-48 triple, and an 11-28 8 speed casette. Already, at this point, my tiagra gs (long cage) rear der. shouldn't be working, as its maximum cog size (according to Shimano's spec docs) is 27t. It looks as if I could even fit up to a 32t cog in there, and the b-tension screw isn't even half-screwed in. Anybody else had a similar experience with a tiagra rear derailleur? I'm looking to upgrade to a shimano 11-34 casette, or at least an 11-32 casette - does it seem that I'll be able to get away with it? I can post pictures at request, I'm just lazy at the moment.
