I am fairly new to cycling (started this summer as a commuter and put in about 110-120 miles a week).
I ride in NYC and have a few hills, most notably the bridge crossing) and though I keep decent speed with the full size bikes on the flatlands, I am passed repeatedly by road bikes when climbing the bridge.
At first I tried to justify that it is the lack of inertia of my smaller wheels, but I am starting to doubt that that is the case. I am riding a Dahon speed p8 with Big Apple Tires. I am light for my size (6'2" - 163lbs) and in fairly good shape.
Any suggestions as to why this is occurring? Is it a technique issue, or is it a bike issue?
