Gear ratio effect.
I currently run 22-19, and was hoping a change to say 18-18 or similar would help my riding. It seems like I cant get enough power into my pedal-ups and taps (just before impact), and was hoping this would change that.
Any comments, critcisms, suggestions? I know there is some low (high) gearing being run out there.
I did read the gear ratio post.

For me 22-18 was just the right amount. I did drop to 22-17 once but doing small moves and gaps was a pain. I'm sure other riders can tell you more but that's what I felt most comfortable with.

22/21 is great...I think that'd be like one gear up from where you're at.

I just changed to a 22-21 yesterday and couldn't believe the precision (used to use 19)...instant ups, higher and with shorter run-up. it doesn't make sense, but I can gap further with the easier gear

22-21 = 1.0476
22-18 = 1.222222
I run 20-19 = 1.0526
I have been debating on 20-18 = 1.1111

God Tobe!
Why would you want to change? 22-19 is what Joe runs and he taps fine with it! I changed to 22-19 a fair few months ago and I tap alot better, you should learn how to tap from a trackstand using 2 full pedal rotations or something, does wonders, its the only way i can do high taps because i cant high taps any other way, well high for me.

I use a 22-19, works ok for me. I tried the 22-21, was ok, may have to try it some more.
Try to do taps with one 1 full rotation, or a little more than 1 bike length, thats the only way I can do them now. If I try to get any more speed or from a further distance I get my timing all screwed up. But seeing some of the other comments about lower gear ratio, I may try the 22-21 again to see what happens.

nicely said pav.
tap the way that works for you toby. what pav might be trying to say is, you will get more power from taking a runup of 1.5 or 2 crank rotations away if you dont break pedal. so you are constantly pedalling the whole time until you tap, instead of getting speed, then doing the final rotation before tapping. i run 22-18 and thats fine, i've often contemplated going to 22-19 but im not going to bother. i dont need it for precision and i feel comfortable doing everything in this ratio. i lost where i was going with that. what i guess im trying to say is change if you really want to change, and if you have a cog lying around. i dont think you would need to run 22-18 though, just have to alter technique/run up for certain moves. by all means change to 22-18 if for gaps it feels like there is no resistance or something. hmm

I think that may be the problem, taking a runup then putting 1 full rotation in at the end. It just seems like there isnt any power from that rotation.
Ill try that out Pav and Alex, and thanks everyone else for replying to my dilemma.

Alexx you put it right.. I was trying a hard-ish tap last weekend with more than enough run up, slight downhill, i found it was easier using 2 wheelbase. Any more than that and i tended to lose too much speed and "rhythm" when rolling into it.
So toby give 22-18 a try. I find 22-19 too "easy" and not containing enough *oomph* for pedal in moves. Sometimes i accidentally leave it in 22-17 and that works ok as well

i use 18:15 most of the time, sometimes 18:16 on my stock.
i used to use 22:21 on my xc geo bike as i needed more power to throw it around, and did mainly static moves.

To be honest I'm a little confused, and Nerds, feel free to attack me you fucks.
Does it make a whole lot of difference what I run as long as i'ts the same ratio, ie; 16-16, 22-22, or 16-18, 22-24? Let me know what the difference would be in bike feel rather than the amount of quasars runing through my chain while it spins. Thanks
