mat hudson Posted April 17, 2007 Report Share Posted April 17, 2007 (edited) haha when i saw this thread "gear ration converter" i thought "stupid guy, you cant get a converter for your gear ratio just a different sizer cog" hahahahahahahai am TARD Edited April 17, 2007 by mat hudson Quote Link to comment Share on other sites More sharing options...
Prawny Baby Posted April 18, 2007 Report Share Posted April 18, 2007 you dont need a convertor or anything confusing like that at all Bren!just divide the front cog by the rear......22:19 = 1.15822:18 = 1.2222:17 = 1.2920:18 = 1.1120:17 = 1.1720:16 = 1.2518:15 = 1.2018:16 = 1.12516:14 = 1.14thats all the most common gears i can think of, and its far easier than using a silly convertor!personally, from those, i think the best are 22:19, 20:17, 18:16, and 16:14. they all seem about right.

ilikeriding Posted April 18, 2007 Report Share Posted April 18, 2007 All three converters or methods seem to be giving different answers Quote Link to comment Share on other sites More sharing options...

abtrials Posted April 20, 2007 Report Share Posted April 20, 2007 just go 18/17 thats the best Quote Link to comment Share on other sites More sharing options...
Prawny Baby Posted April 20, 2007 Report Share Posted April 20, 2007 just go 18/17 thats the bestno it isnt.gear ratio is all down to personal preference really, although, that said, MOST people will find 18:17 FAR too easy..... i rode porters ashton with 18:17 and it was stupid..... so light and flicky for gaps, but SO spinny for anything with speed.chris: didnt look at your sheldon convertor, as ive only ever needed my way ive only ever run 170mm cranks, and a 26'' wheel, so i only ever need to work out equivalent ratios for my otherwise unchanged bike, as is probably the case for most people.really wanting to try 18:16 soon with a heatsink bash, but dont know if itll be a TINY bit too easy, i know 18:15 will be too hard Quote Link to comment Share on other sites More sharing options...
br3n Posted April 20, 2007 Author Report Share Posted April 20, 2007 I used to run 20:18 but cant remember if I then changed to 20:17Either way Im going 18T front now and need to sort out the rear cog size... doh Quote Link to comment Share on other sites More sharing options...
