What's your favourite gear ratio?

60% speed and 40% cocaine.

ok now I think I need a faster ratio, should I make the rear cog smaller from 17t or chain ring bigger from 47t ?

cheaper to do the rear cog and you still have lottsa skid patches

No.

Pedal faster.

Currently running 42/16, perfect for where I live as there's a decent climb on the way home from town/college.

Would there be much of a difference with 42/15? I find myself spinning out on the descents most of the time, but would it be a lot harder on hills?

42/15 at the moment, and loving it thus far.

51/19, finding it slow: is going to 17 or 15 going to hurt much?

Only if you crash.

51x19 sounds perfect to me...

my commute is mostly straight and mostly flat, so looking for more top end speed

so the title is "what's your favourite gear ratio?"

I'm not too clever at maths, but the likes of 50/19 is not a ratio. wouldn't the ratio be 2.63:1

in that case, 51x17 shouldn't be too heavy.

51/15 is too high for riding on the road.

51/19 sounds good, just spin faster

don't know if you skid much but 51/17 is one skid patch (or two if you skid with either foot forward). whereas 51/19 is 19 and 51/18 is 6.

49x17 for real deal
47x17 to sit back and relax

you got a flip flop crank?

I hadn't realised it was so few patches, I do have a 52T I can swap it out for, 52/17 gives a mucho patches. I want more top end speed whilst maintaining my cadence, and making sure I don't get pwned by fair-weather nodders on hybrids. Got overtaken by one today: Fair play the guy had calves like Wiggo (so not a nodder at all, far from it) but it was still a hybrid. Said 'alright mate' as he went past too, which was nice.

44x17 is what I run.

^ Is that not incredibly spinny or do you live at the foot of a mountain and work at the top?

How spinny is "incredibly spinny"? Just out of curiosity, mind.

44x17 is not incredibly spinny, doing 20 mph you'll be doing around 95 RPM.

going from 44/16 to 47/16. looking for some more top end and a bunch more skid patches. win win.

I found 48x18 which is about 72 GI far to spinny on the flats, 44x17 is under 68/9 GI so I would imagine it would be quite spinny. Maybe not to others, each to their own I guess.

60gi is spinny
50 is incredibly spinny
40 is only for polo.

68 is pretty standard, remember that most people don't just ride 'on the flats' (I'm assuming that's a reference to topology rather than pedals)

It's pretty hilly where I live but I had always been under the assumption that anything under 70 gi was gearing down. It's all about personal preference I guess, ride what your comfortable with.
