What's your favourite gear ratio?

'Cross and track.

Well I guess I'd race a crit if one came up.

36x17 to 51/15 depends

51/16 on the street

That's a pretty spinny gearing, even for London.

Right now at your ages, you should be in a dirty little hostel in France working for a small team.

64 isn't that spinny for winter

Mash2trash.

How does winter make a difference? Do the wheels expand in the cold?

The waste heat from pedalling above your most efficient cadence keeps you warm.

stink or shrink?

It can be whatever you want baby.

I've just put a 19 tooth on the back for very hilly audaxing (just happen to live on / near Andy Corlass' turf) I've a double fixed on this bike, I've never had double fixed before.

So here's my question. Most t'internet ramblings say that a 1 tooth difference is best. But as already mentioned I live somewhere hilly - however, I do like riding to the coast. So I reckon a 2 tooth difference would be better. Am I right or is two teeth difference too much and I'll regret it on my next coastal run?

Currently have 48/17 and 48/19.

Best for what? Last time I rode out to a hill climb, I found a 5 tooth difference (16/21) was best :-)

I'm currently running 47/18 and it is far too spinny. Probably why my testicle stink, hey @edscoble

5 tooth on a double fixed or did you change at the hill climb?

Turned the wheel around at the bottom, turned it back at the top.

47/18 isn't spinny.

47/18 isn't spinny

It is if you're doing 25mph

Oh nice, I was thinking off sticking a 15 on for the flat coastal bits. Now I know it is do-able.

If you go from 19 to 15, your wheel moves back half an inch. Make sure that's still going to be in the track ends before you buy a sprocket :-)

I love the feel of 48/16, but one skid patch...

47/18 isn't spinny.

I think I'll skip the 17 and jump to a 16 on the back.

Two.

That's a pretty big jump, from 69GI to 78GI.

Go for the 17t, that work out 73GI.

Just where do you live that you actually find a normal ratio too spinny?
