RonB thx for feedback. I’m totally unfamiliar with what hills may be present. Heard there are a few on the Karras loop day? I am pretty comfy riding at 16-18 with this setup. Get spun out quickly if any faster for sustained pulls. On my geared bike I like to roll at 20-22mph most times. Was thinking going 46/16 just to get a bit more speed outa the roll in the flatter areas. If I can climb in that for short distance maybe that is better suited, plus when I wanna go slow and since not racing, slower feet are OK too. maybe I’ll just bring the extra chainring and chain … change if needed.
