Honestly I think that my aggressive riding combined with 53x18 gearing could also have something to do with it. In my area there's a lot of intersections and usually I'm not into cutting red lights or doing weird shortcuts so I just stop. When I start I'm clipped-in, standing on pedals, wobbling bike and using lot of force to accelerate as fast as possible. It turns into semi-sprint after which I stabilize my ride. Sometimes it takes less than 300 feet and I have to stop and repeat the cycle. This gets combined with potholes, uneven terrain and other debris that I have to jump over(which puts lot of stress on drivetrain when landing).
Anyway, I bought SRAM PC-850 for my geared bike and Izumi 410 for my singlespeed. Izumi chain came with spring clip, I didn't use it just connected chain using chain tool, I wonder if it matters.
