think 41/40 - 17 is the norm Greg but could be wrong $:-\$

You rang?

39:17 is same as 44:16 on a 20" and is what I run on my NS race cruiser.
41:18 is just a tiny bit lower and was very popular BitD as an all-round okay for all tracks.
36:16 is a bit lower again and same as 43:16 on a 20"

Next question

As a general rule, Front teeth no. divided by rear teeth no. multiplied by wheelsize (whatever you are calculating, I.e 20 24 26...whatever)

EG

44/16 x 20 = 55 (the magic no)
43.5/16 x 20 = 54.37

34/15 x 24 = 54.39 ...... badabing

4 inches give or take, taking into account knobblyness of tyres, tyre pressure, n sole thickness

you can drown in 4 inches of water so an extra 4 inches of downward velocity is gonna fook you up big style, stick with 20s dude, its lovely down here

Try this table out based on some different gear ratios, the 39 / 17 one in the middle looks like the most optimal but it will depend on your choice of tire as well as this also plays a part in gear ratio's. Looking at this chart though your 36 / 16 might be a bit shorter than youre after.

SHORTER (EASIER)
36 / 16 - 2.25 (54)
34 / 15 - 2.26 (54.4)
41 / 18 - 2.28 (54.6)
39 / 17 - 2.29 (55.06)
30 / 13 - 2.30 (55.38)
37 / 16 - 2.31 (55.5)
40 / 17 - 2.35 (56.47)
TALLER (HARDER)

Gregster, slap a 39 tooth on the front, get the tyres pumped up to a good pressure, get the bars to an angle and height to suit you and all will be fine. A 39:17 will not feel too high for riding on the roads and paths, and will be fine for track use

Dark Diggler · « **Reply #15 on:** March 07, 2012, 03:56 PM »

52/23 is an often overlooked ratio and is nearly what you need
