guys can someone list me gearing for 24 cruiser ride
i want it to run ideally at the same as 43.5 /16 on a 20 incher in the perfect world
at moment it comes with 17 rear and 40 front
i have when i check they fit a 14t/12t /16t/rear cog spare and or a 44/36 and 39 from spare if any of these combos do for me
-
think 41/40 - 17 is the norm Greg but could be wrong :-\
-
I too am keen to know this info, I was all lined up for whacking a 46/16 rig on. :buck2:
-
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 ;)

im being a pain now john i know i spoke to you lasy nite about this and forgot everything yopu said lol.
i remembered you saying im sure i want to get 43.5/16 eqivelant as 40/17 is to hard for me so is 36x16 a lot different or tiny tiny bit .
sorry to be pest but i wanna change it tonite if i have the right bits ready for a run out

43.5/16 on a 20...closest is 34/15 on a cruiser :daumenhoch:

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 :LolLolLolLol:
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 :LolLolLolLol:

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