What's your favourite gear ratio?

If you had a triple, what would your cadence be up hills I wonder?

hippy So, if you are slow, stick with your 60rpm.

I think you might have willfully missed the point. ;P lol !

Moi.. willfully ignore a point.. well I never! Hmmpfh! Filthy swine! I challenge you to a du-el!

hippy If you had a triple, what would your cadence be up hills I wonder?

I used to have a triple - my cadence sitting down on hills was still about 60-70rpm. I just went a fuck of a lot slower ;(

I don't believe you! "slower" and "hills" in the same sentence! Liar. ;)

I used to quit on hills. Not even very steep or long ones. If anyone wants to take solace in that fact, be my guest.

No. I will ignore your previous comments. You are clearly distressed or intoxicated.

Reserrecting this thread for some aid: first few rides on a fixed and thinking I need a bigger gear. I'm on a 42:16 which is about 70" but feeling I can't put the hammer down as much as I like and it feels a bit spinney. Don't think I need to increase massively, but a bit bigger I think is needed (particularly for the downhills: I live in Cheltenham). Do I need to change both cogs? Or maybe just the front one to 44/46?

domt know if this has already been posted coz i cant b arsed to read the whole thread - might b useful for working out gear-ratios/skidpatches.

48 x 18

52x18 which is turning out to be a bit shit might get a 49 tooth

42 x 17 on 700c x 23, SS not fixed.
Suits an old boy like me !!

44 x 17/16 on 175mm cranks, pretty good for C. London
17t puts me just under 70 gi
16t puts me just over 70 gi

gonna try 44:16 then, gives me a mid-70s and I'll see how I roll

48 x 17 fixed
52 x 18 ss

very useful

But i'm thinking that 47 x 17 is probably round about right - puts you at 72 gear inches. i find that i cant get as much speed on flats as id like, and i could handle a bit more on tough hills............

48t x 18t.
170
72.0
oh yeah!

I find 48 x 16 too spinny :( anything below 48 x 14 on 700c (90") seems spinny.

My acceleration off the line (lights and so on) is not the fastest (but not bad) and I need to be steaming along to get up steep hills :( but boy can you get up some dreadful speed on 48 x 14 and a decent pair of legs on London's flat streets ! :)

All this talk of what is and is not right for various terrain doesn't really take all the factors in, like leg length, strength, short twitch to long twitch muscle ratio (we all differ by a fair amount - certainly more than a cog or two) even crank length (leverage). Building and riding a very light machine will also impact on acceleration, stopping and so on.

Just have a fixed filp hub. Big gear to make you feel like a man and a smaller one to be human!!

i ride 52-17 SS. its fast as hell and ive learned to ride it well after years of SS on various bikes in hilly cornwall.

47x17 would put you closer to 75 GI. it's what i run, currently.
