Highest gear much harder to pedal after repair - did the repair break something? I recently bought my bike in for repair and I got it back and I've noticed two separate issues that are causing me some concern and I wanted to ask this community what they thought of it.


The hardest gear is MUCH harder to pedal than when I first bought it in.  I'm talking some he-man strength to get this thing going.  
When in the hardest gear and pedaling it feels like you can FEEL the chain, I don't know how else to describe it, but there is a feeling in the pedals.  This is only in the hardest gear, the other gears are ok.
If you only feel the chain when in the hardest gear, maybe the chain is rubbing somewhere or maybe the chain is being squeezed by the frame of the bike.

Put the bike in the hardest gear and turn it upside down. Pedal by hand while seeing if the chain has enough clearance everywhere. You may find your problem this way.
