i kinda sorta want to try 160mm
On the one hand, any crank length shorter than too long is hard to distinguish from another in terms of performance, so go ahead and have fun.

The updated rotor track crank comes as short as 150mm. i kinda sorta want to try 160mm
On another note. I recently purchased a road bike. After two weeks of riding and one charge of the di2, I went to downshift on rings and the chain crapped out a moment after I started going up my driveway. I looked at the chain and thought hmm maybe I can pull it out from under the derailleur where it was stuck. I broke the derailleur and missing a small screw because of my ignorance. My lbs told me I should try ebay as that dura-ace groupset is no longer in production.
