What's your favourite gear ratio?

48/17.

Great for in the city.

49/19. this is about 70GI and gives me 19 skid patches... which is good cos I love a big old skid-up.

Also a big fan of 48/17.

39/14, but thinking something between that and 39/15 (or 42/16) would be about right.

41x15 or 41x20. I can't make up my mind.

69x2

I tried 69x1 but prefer the more involved feeling when I share.

51/9 on the rollers - 70mph @ 158rpm

44/17. A commute friendly 68GI. 17 skid patches too - more than a man could wish for.

This week I am mostly enjoying 47-18. Was a good gearing for the ride to Cambridge too.

im changing to an from and 47/16 to a 47/18, just cos i tried it recently and it was just such a piece'a'piss getting anywhere, up any hill,no sweat.
starting and stopping just a dream !

oh and skidding, but i dont really do that.

I have a 1968 Parmount frame I am building it up, what is the headset 1 x 24 t.p.i. BSC --------------- 25 x 1 ------------------ 25,4 x 24 F ????
Thank you,

you guys all love your high ratios, i can't get enough of my spinny ratio

41/17

49x17 FTW

Converted my 48 : 17/16 BJ to climbing modus last night. Now 41 : 23.

The 41T chainring / 144 BCD campag pista crankset combo looks well strange, and the shiny undrilled 23T cog on the back looks like I nicked it from a table saw.

Taking it for a test ride tonight, on a 1.5km hill I found with a slightly higher gradient than the weekends mountain climb. Better bloody get on with this ratio, or its going to be a painful weekend. ;)

how many skid patches would a 42:18 have?
and how do you work out the GI????

3 patches for that setup...

ta

It's all about 1x1 this week.

^ penny farthing stylee, fast as fuck when you get it going- bit tricky to skid at the lights tho

shiiit - runnin 49:14 feels super fast never overtaken on the seafront but according to that chart got 2 patches... gaining another tooth ASAP!!

Just changed mine from 48:18 to 48:17 and at the moment I'm preferring it.

But 1 tooth does feel different - even on a fairly flat 20k ride.

22x28

it's all about 0-5mph acceleration this week

39/23

im now down to 47x18 (68.8GI) from x16 (77GI)and the muscle burn is tremendous!
i highly recommend it,
my hamstrings especially burn like nothing before.
i cannot however for the love of god, get faster than about 25mph even down hill !
i think my cadence sucks, maybe cos i was so used to grinding it out ?

Go down some steeper hills :-)

surely the point is to work up fitness enough in your big gear, then being able to spin it well, maxing out on downhills. perhaps go for about a 72 and then gradually up it

48/16 fine for me....tried a 48/14....briefly....
