Got 39-16 on a newer Floval which works well, or 38-16 for commuting if I'm feeling lazy. Problem is old school bikes and getting hold of a chainring in the high 30s. Got a project on the go at the moment with a 42t so will probably go for 18t on the back and see how it goes.

ran 36-16 on me floval flyer and using the same on me kuwi. quick out the gate and acceleration but you got to be strong in the legs to get round the track.

 I usually run 41-17...It depends alot on your legs and enviroment (downhill or flat..)
 If you can,try out a couple of variations to see how quickly you pedal out...

Great thanks Guys , that makes sense cheers

Dingo , had someone look at tthe weld , and they have said that to be fair , the weld should be stronger than the metal and to ride it, if it breaks he will fix it with a plate under the BB shell , but to not bother as it is not cosmetic i am bothered about.

we shall see , i am only going to cruise on it anyway.

Then do you need to factor in the length of the crank as well? I presume the longer the crank, the more leverage you'll get...so you can run a bigger front cog?

So, if you're running a 36-16 on a 26" wheel with 170mm cranks, you could run a 39-16 with 175mm cranks? Does anyonw know an offical wheel size : front sprocket : back sprocket : crank length ratio/calculation?

Confussed.

You think its confucing now, wait till you start taking the replys to this into consideration.

But also tyre size makes a huge differance ie 1.75, 1.95 etc.

I use 30/13 on my cruiser.

I thought it best to try pretty much every gearing until I find one that's comfortable, allows me to pedal without feeling like my lungs are about to burst and doesn't make me feel like a fat git on a kid's bike.  The search continues.
