Giant ocs3 problem
I just bought a Giant OCS3, and the chain rubs against the inside of the middle front sprocket when it is on the lowest rear sprocket and lowest front sprocket. Is this normal********** It is definitely not rubbing on the derailleur. I can see it plainly catching on the rivets that hold the sprocket.

Riding cross-chained is not a good idea. Avoid using small-small and large-large combinations. Try to keep a straight chain-line. That rubbing is just about unavoidable with what you're doing.

Instead of low/low, go middle and middle or middle and high. The chain has to transition far too much laterally with low/low, as well as high/high. You're losing efficiency running that way as well.

....thanks...
Okay, so it's normal given the lateral degree of change between gears. I wasn't trying to ride like that, just adjusting the derailleur on a stand and noticed the drag as I shifted through the gears. Thanks for the lesson! Can't wait to get up tomorrow and take her on her first real ride!
