Resistance w/ Jockey Wheels
So I bought a used xt derailler off ebay and I have been preparing to install it on my bike. One thing that I've noticed is that compared to the Deore derailler on the bike these jockey wheels seem to have a great deal of resistance to spinning. They turn just fine but it takes more effort to make them turn. Is this an indication that they are worn out? I can see about replacing them but I only want to do so if necessary.
