Mystery squeaking
I recently purchased a 2016 Trek 1.2 and have so far 178 miles on it. The other day, I started hearing a squeaking noise while pedaling . It seems to be coming from the bottom bracket / crank area on the left side and only occurs on the down stroke of my left foot. It sounds like rubber squeaking. The LBS was unable to duplicate the sound. Yesterday during my ride I discovered that when I am going faster than 17 mph, the sound disappears. I use toe clips/straps and have eliminated that as a possible cause. Any ideas?

The bike is new. Figure out how to duplicate the problem on cue, ie. hard pedaling at low speed in a high gear, climbing, etc. and do it for the shop, or have them eide it under those conditions.
I suspect a crank to spindle or BB issue, but these can be a bear to diagnose, and there's no reason for it to be your problem on a bike this new.
If you want to do something before going to the shop, borrow set of pedals and switch to rule your pedals in or out, and narrow the suspect pool.
BTW- I suspect that the speed itself has little to do with it. However as you reach cruising speeds near the high end of your range pedal pressure is usually lower than when climbing, accelerating or pushing a bigger gear at lower cadence.
