Single Speed conversion for winter
I've been practicing treating my bike as a single speed for a bout a week (100mi+ without changing gears). I have an '07 Trek Soho (link
) with the stock gearing setup 42 x 11-32 (9spd). I've been riding in 42 x 18 (2.33ratio) with slick tires and found that at a comfortable effort and cadence, I'm rolling 17-18mph flat, 13-20mph on hills.
My plan for the winter is to convert to a single speed with (eccentric BB so it will be an easy convert) a studded front and cyclocross rear. While I know that at the same cadence, my speeds will be the same with a 42 x 18 setup, but I'm wondering if the extra weight and grip of the new tires will cause significantly more effort.
Should I go with a 42 x 19 instead for slower speed or just work a little harder on the 42 x 18 until my muscles make the extra work feel like it's normal?
