Just got a new bike with Shimano Ultegra 10 speed. At it's 500 mile tune up today, the shop guy said my chain was already stretched to the replacement point. I am not a hammerhead but do ride in the mountains and keep my rig clean. This seems waaayy too early to have to replace a chain. I am used to getting 2,000 on average.
Before I assume my LBS is scamming, is there any news on Ultegra 10 spd chains having shorter than normal life spans?
