I would suggest 18-21 with rubbers, depending on grip and layout. Lower sizes for high grip and/or tight layout. For foams I'd go up one to three teeth depending on diameter. With 84t spur and 63mm rubbers, ratio & rollout calculations: pinion / internal ratio / rollout 18t / 7.933 / 24.948 19t / 7.516 / 26.344 20t / 7.140 / 27.720 21t / 6.800 / 29.106 With 84t spur and 60mm foams ratio & rollout calculations: 18t / 7.933 / 23.760 19t / 7.516 / 25.080 20t / 7.140 / 26.400 21t / 6.800 / 27.720 22t / 6.491 / 29.040 With 84t spur and 58mm foams ratio & rollout calculations: 19t / 7.516 / 24.244 20t / 7.140 / 25.520 21t / 6.800 / 26.796 22t / 6.491 / 28.072 23t / 6.209 / 29.348 With 84t spur and 56.5mm foams ratio & rollout calculations: 20t / 7.140 / 24.860 21t / 6.800 / 26.103 22t / 6.491 / 27.346 23t / 6.209 / 28.589 |
