The flatness of the rail trail allowed me to fully explore the range of gears I have now. My old bike had one chainring up front and 7 cogs on the back cassette so the range was small. My new set of wheels has 3 chainrings up front and 7 cogs on the back cassette and cycling through the various combos was a treat that I have not had yet since I got my bike last week. I discovered the power of the large front ring combined with the small back cog. WOW! In general it was great to have the opportunity and I'm sure it'll take another such outing or two to find the sweet spot and ingrain the patterns in my head for the right gear combos for climing and downhills.
One more reason to love my new bike! Like I don't have a ton of them already. Love it so much I bought a bell for it today. Brrrrrriiiinnnnnnggggggg.
