modrider666 Posted August 24, 2005 Report Share Posted August 24, 2005 20:14 That should be perfect (Y) Quote Link to comment Share on other sites More sharing options...
JT! Posted August 24, 2005 Report Share Posted August 24, 2005 20 front 14 rear will get you a ger ratio of 1.42 (1.50 is the most desired gearing for a mod) So having 14 on the rear will be your best bet. You can get a 14t freewheel. A few have used them and they seem ok. But you must have a flip flop thred on your rear hub. Unless you have a profile or a king or something then just ignore everything i just said. (Y) Quote Link to comment Share on other sites More sharing options...

trialsriderjim Posted August 25, 2005 Author Report Share Posted August 25, 2005 13 on rear is a bit harder 14 on rear is a lot lighter ← i have 18 to 12 now so wood 20 to 14 feel the same Quote Link to comment Share on other sites More sharing options...
trialsking 55 Posted August 25, 2005 Report Share Posted August 25, 2005 nope it would feel lighter. from what i have just read i'm guessing: 20:14:lighter 18:12:perfect 20:13:harder Quote Link to comment Share on other sites More sharing options...

Mark W Posted August 25, 2005 Report Share Posted August 25, 2005 I used to run 22:14 on my T-Bone 'cos I'm butch as f**k. On an unrelated note, I'd go for 20:13, but get some longer cranks. All the power of 20:13, but it'll feel as easy as 20:14. Works for me with 175mm cranks and 18:12 on my T-Pro :( Quote Link to comment Share on other sites More sharing options...
trialsriderjim Posted August 25, 2005 Author Report Share Posted August 25, 2005 ive got 165s is that to short for 20 to 13 ? what wood 20 to 14 be like with 165s? Quote Link to comment Share on other sites More sharing options...
Mark W Posted August 25, 2005 Report Share Posted August 25, 2005 They're not "too short", it's just that longer cranks mean that you can run a harder gear (and therefore have more power, which is a good thing) but it'll feel easier, because you have more leverage (so you can get to the power more easily :(). But f**k it, just run 20:14 :( Quote Link to comment Share on other sites More sharing options...
JT! Posted August 25, 2005 Report Share Posted August 25, 2005 20:14 will feel more like what you got than 20:13. It will feel slightly lower/lighter. Quote Link to comment Share on other sites More sharing options...

monkeyseemonkeydo Posted August 29, 2005 Report Share Posted August 29, 2005 Megamo ran 20:13 on their mods when they used to use 175 cranks. However when I got my first Echo EM2 I had to change my gearing to get the chain length acceptable. I was running 20:13 on 158mm Monty cranks and got on just fine with it. I'd say 20:14 will be too easy (unless you're a newbie) and would go for 20:13. Or you could just go 18:12 like 99% of the mod world...
