Look up "cross chaining" to see if that is your problem.
If you are on the smallest ring, the smallest cogs will rub.
If the largest ring, the largest cogs will rub.
That's normal.
BTW "ring" is on the crank and "cog" is on the cassette.
Yeah I just checked. Its a 52-42-30.
So really my only option is to replace the whole crankset. A 39 would work nicely though. Do they sell a 39 for the FC-5504/5505 set?
My only fear about keeping this set up is the rubbing will wear out my chain faster. I already see globs of lube on the sides of my derailer. Also the Derailer will wear down faster.
I guess now that I am aware of the problem I have to just not be in those gear combos at all. It sucks because I like to cruise on the smallest cog and the smallest ring. Gives me great acceleration. What's great is the middle ring has trimming so I guess I'll just learn to cruise on the middle ring.
