is there something wrong with my pedaling technique?
To preface, my Bike Friday just came back from an overhaul and has new cassette, chainring, chain (as well as other parts). There is nothing mechanically wrong with it. Before I sent it off for service, I had changed out the cassette and chain (they put a brand new chain on during service anyway).
Here's the question: sometimes, but not always, when I either stop pedaling to slow at a street ending, or when I am starting up from braking, the chain will skip one link or tooth. This does NOT happen when I stand and climb a hill. It only happens when I go from a very slack position to a slightly tensioned position. I am not mashing down hard when I resume pedaling, I mostly spin in easy gears.
I'm wondering if it is somehow technique related and has to do with how I relax and resume pedaling? It happens maybe once or twice a ride at most and it's not particularly jarring because I am not pressing hard, but it would be if I was mashing down.
Any ideas on what is causing this?
