Chain set / chain rings - FSA Dynadrive 48/36/26
Shimano Deore front and rear derailleurs
Chain - KMC
Bike usage - roughly 600 miles since purchased, road and bike trails, but not off road / trail; Some hill work (but generally in small chainring for those), and really only using large chain ring when on flat roads. Novice rider, so not huge power output, and rides average 80-85 cadence rpm, topping out 100-105 very occasionally. Rides are generally between 10-20 miles
Edit re "cross-chaining" - when using the large chainring I would tend to be using smaller cogs of the rear cassette, to avoid cross-chaining
Please take a look at the picture - hopefully you will see what appears to be different shaped teeth on the front large chain ring. Some appear quite pointy, others rounded, and two or three almost flat, as if the apex has been removed.
My question(s) - is this excessive wear and if so, caused by some fault in the drive train? Or has the chain ring been manufactured with these differences in the teeth? If there is a likely fault I can go back to LBS, but what are the likely causes? If deliberately manufactured that way, why?
