OK, OK, it's probably the helmet cam vs. my handlebar-mounted cam then I have noticed that helmet cam videos look faster than handlebar cam ones

Speaking of gears, I put the same setup on my road bike last summer and it rocks! The bike is a 2011 Specialized Dolce Triple that came with a 13-26 cassette and a 30-tooth small chainring. After a sufferfest of a climb up Donner Pass Road, I replaced the cassette with a Shimano MegaRange 11-34 and the small chainring with a 24 (see, I told you I suck at climbing). After doing all that I had to replace the rear derailleur with a Shimano Deore long-cage mtb derailleur.

That Sirrus hybrid I rode in my video I bought used and it only had a 24-tooth largest rear cog and a 28-tooth small chainring. The 11-34 cassette/24-tooth chainring combo is the lowest gearing possible on both bikes.
