Gearing

Recommended Posts

Hi all

I was just wondering what gearing you would all recommend on my zoo pitbull for street. I know it comes up all the time but there was nothing precise in the search, i have a 22 on the front and a 17 on the back i run a hope xc but i was thinking about changing to a fixed hub with a freewheel. The best freewheels were all in 18t can some one help?

Thanks

Dan

The gearing you're currently running is pretty hard. A lot of people run 22:18, this would probably solve your chain tension worries in the other thread too.

I've always thought that the most commonly preferred gear ratio in trials works out as 30 gear inch, This is a measurement of gearing taking into account the wheel size. The ratios in yellow are all the ones around 30 gear inch. There's quite a few options. But depending on what you like there are loads of options of what you could run nearish to 30. The front sprocket size is up the left and the rear along the top.

see you have done it the complicated way IMO. but cheers anyway

when i calculate it i normally divide the front cog by the rear cog. then higher the number = stiffer......

suppose your way is correct when your wondering which gear is best for each bike size etc etc, where as mine is better for finding how much stiffer a gear will be.

meh

Yeah, I ride 24", so to compare stuff to other peoples bikes its easier to do the gear inch calculation.

Ive had a variety of ratios over the years

22-20

22-19

22-18

22-17

22-16 (yes I know hard, was an accident and didnt realise)

20-17

20-16

16-13

16-14

17-14

I have to say out of the lot my favourites would be

22-18

20-17 (possibly the nicest)

16-14

17-14

They are all pretty similar, I am on 17-14 at the moment, its abit harder than 16-14 but abit lighter than 22-18. Its between 22-18 and 20-17, good for taps as speed can be built, also good for techy stuff as its not too hard that its a mission to use, yet its not too light for rolling gaps etc.

Im running 18:16

But 18:18 felt really nice on Gavin Badfords Bedfords ashton.....

I disagree with you there, really horrible for street, but apparently benefits for natural according to the man himself. But meh, seems too light. :rolleyes:
