The reason i don't want a standard 11-23 or something is cause when i do hit the odd hill (my 1km driveway) i want the 24 and 28 climbing. The 49 or 50 big ring was just something else i was tossing around.
oh....I see....I put a 11-32 with a 53-29 set for my brother and he loves it [had to put a mtb r-derl on and a new chain] I works to for hil b/c he has never had anything other than 6 speed so the jump to 9 speed was almost mind bogl-n for him.
