Dave and I (and his teenage son) got together for another bike ride today. We spent almost an hour on dirt, with only a short chunk of pavement which was between his house and our route. Nothing fancy; just getting in some seat time. Dave has decided he has ridden this borrowed bike enough to know what he needs/wants in a bike of his own. He thinks he is ready to start shopping around.
After our ride was over, I decided to count teeth and compare gear ratios between the three bikes. Here is what I learned.
Dave's borrowed Fezzari (1x11 setup): 30-46 for a low ratio of .65 (on 27.5" wheels)
His son's old Specialized Rockhopper (gifted from the same neighbor): 22-32 for a ratio of .69 (but on 26" wheels)
My Marlin: 24-28 for a ratio of .86 (ouch!) on 29" wheels--the tallest of the group (ouch! x2)
After doing this math, I decided I really want a lower first gear. Kevin pointed out a gear set on Amazon, and there is one (not the one he linked) which shares the same general model designation as my stock one--TZ500. From what I see online, this set's taller six gears are identical to my current setup; only the shortest one is changed from 28 teeth to 34 teeth. On the plus side, that would put my low ratio at 24-34 and works out to .71, getting me much closer to my co-riders (though I still have taller tires). On the downside, this would mean I'd have a huge step every time I shift from 1 -> 2 or vice versa since the 2nd gear has the same 24 teeth as my current setup. It would be much more practical if they spaced out the other gears to match.
Anyway, just thought I'd follow up with my findings.
