Gear inch/ratio question

bit high, maybe, i go 48 x18, was doing 48 x 17, which was ok as well, but a bit grinding on the hills. anti-clockwise till i die.

I rarely get the chance to do circuits, but I commute from Ham Gate to Roehampton Gate every morning and 48x18 (23m tyres) is about perfect for the steep, but short climb from Ham Gate.

It has got to be clockwise. Did a lap on 48x16 (SS) a few weeks ago. Felt like I was going to rip the bars off grinding up Suicide Hill. Either that or puke my internal organs.
Now running 48x19 fixed which is an altogether more civilised ratio for that terrain.

anti clockwise with the odd clockwise lap for variation 73inches 25c 170 cranks, it seems perfect to me, the hills aren't long or steep and if it's not windy and am feeling fit will ride seated all the way round.
i do weigh the same as a ballerinas fart though and do like to get up the short hill (broomfield) reasonably quickly and will usually sprint the last bit and then keep the speed up along the straight until the next carpark

anyone know what gearing the 2006/07 wrongsters shipped with? a mate of mine had his nicked and wants to replicate the gearing on his new bike

50/14

42 x 16

Totally. With 15mm cranks to really work those calves.

i work on my 14/44 gearing with my 170 cranks nice combo me thinks. not too easy so that your legs get weak but not too hard that lactic acid wins the day.

as for your original question, no fucking idea :D

I think 42x16 based on some googling but you'd have to check the website.

42x16 according to this, 16T freewheel as well..

2006 (black) shipped with 48x18 freewheel (no fixed)
2007 (rust) shipped with 42x 16 fixed/free as seb/hippy have said.

If it's the '06 black one it was 48:18 [EDIT] - Well mine was anyway.
But the 07 rusty ones and all wrongsters since have been 42:16.

cheers guys!

my '06 was definately 48:16.

my head just exploded.

mmmm, my '06 was 48x18???????

ok i'm 99% sure it's 16. i have given my original wheel to my flatmate. i will count teeth tonight.
surely it had to be uniform across the entire distribution right. there's no way they changed it is halfway through production?

defo 48:16 on the 2006 black ones, they eased it up after that, and slackened the geometry - Pretty sure they didn't change gearing mid-year. I got mine super-cheap on trade at the end of the season (as everyone at work seemed to) and once you swapped the pig of a fork they're a nimble little ride.

Check the 'archive' on the Sp website for later specs.

ha ha, Langsters. I only wish Pista's weren't around, then they'd be the most hated. hee hee.

my '06 was 48x18, bought early on in year

48 X 18 looking at mine right now . . and the fork on the 06 is one of the best things about it

Heres the blurb, which says 16t, but mines 18 and aint ever been fiddled with ?

Hi, sorry to ask again...

Can anyone give me some advice on gear ratios?? I'm getting my first singlespeed freewheel custom built, and have been asked what gear ratio I want. The standard he (the guy that's building it) uses is apparently 52T 18T. In one of the threads, it seemed like most people were going with 48/16 or 17. is this wildly different, and if so, how?

I have read the other threads about gear ratios and am still confused! Sheldon Brown's calculator was fine til it got to the "chainrings" bit.

This will be my first commuting bike, my heart's set on a singlespeed, but I didn't realise it could be so complicated.

If it's any use, I'm 5'4", female and only moderately fit. Cheers muchly.

give this a whirl

46 - 18 would be better.
The ratio he wants to give you isn't going to make for a fun ride around town, too long to get up to pace.

+1 to what ma3k said, ideally you'll want to get a GI or anywhere between 65-70", for riding in town, the gear inch calculator that tick.tick.tick posted is a good one and will show you different alternatives to get to the magic numbers, anything over that is a bit big, for a first timer, you'd get used to it, but it'd be difficult to spin and come winter it'll be much harder.
The only issue is whether you'll be riding using 700c tires or 650c, that will make a difference, but you can select tire size in the calculator as well..
