What's in your stable? What is the bicycle you ride for commutes? And why do you like it?
Pics of mine later...
Felt York fixed gear
Diamond Back Hanjoo cyclocross
Soon... Surly Cross Check.
I have a feeling you like Colnago bikes. 2015 Colnago world cup - one I wanted a whole back.
They are the same, except for the ways in which they are different. #1 is aggressive and eager, always ready to go and get there yesterday. #2 floats over everything and can coast forever, but will not object to a burst of speed. I rotate them based on which one I could afford to have serviced more recently. Neither commute anymore, and I'm sure they hate me for that.
Cross Check frames are like a Jeep of the commuter bikes. Versatile and won't let you down if you take care of it.
