    I believe most stock bike riders run a 22 front, 18 rear. This results in a gear ratio of 1.22 to 1. I'd recommend sticking close to this, as a 22 tooth front sprocket is standard on most mountain bikes, so they are easy to purchase. Many stock bikes use a road bike rear cassette. These are typically lighter than a standard mountain bike cassette, but more importantly, the gears are closer together, ie: 11 to 24 tooth versus 11 to 32 tooth for most mountain bikes. Try to get a cassette with a 17, 18 and 19 tooth gears, so you have some versatility of gear selections that are right around the commonly used 18 tooth sprocket.

    i prefer a lower gearing, i use 22/21 mostly, 22/19 and 22/18 sometimes, but not often

    I run a 20/17 on my stock bike. I think the 22/18 gear is the most popular for urban trials, but lower gearing is popular for natural. 22/19 used to be my favourite, but king kogs aren't available in steel in 19t, so I changed. Mine is good and I can still do rolling stuff fine. If you're using thread on cranks and using a freewheel or fixed cog though, an 18/15 or 18/16 will be OK. 16/14 is pretty close to 22/19 as well if you want to save more weight and gain more clearance.

    road cassettes are the best for trials if you want gears. I'm sure you can get a shimano sora, tiagra or 105 in a 12-21 ratio, which should have 17/18/19/21t rear cogs, all you need.

    Crank length will effect your gearing as well. If you are running longer cranks (175mm) plan on going down one tooth in the back to compensate. For example 20-17 on 170mm cranks is sweet for me but I spin out with the same gearing on 175mm cranks.

    i just bought a 19t... weird.

    also, i just went from 22-18 to 22-19 and a longer bike. I liked the 22-18 a lot on the shorter bike, but it was so much effort to get the front up on the longer bike. 22-19 helped out, made some moves more effortless, but i do miss half-pedals with the 22-18. 22-19 causes me trouble and i cant' up quite as high. of course, i can't up very high anyways, so its probably more technique than gearing ;)
