How many inches ?

[Smurfy]

I'm running 28mm tyres so I should be just over 21mph at 120 rpm, so not quite so mad!

I'm still undecided on what my first fixed sprocket should be, it will probably be 18T, which is the same as my freewheel. However, after my most recent ride I was feeling that I could definately use 19T to get up the hills.

What type of routes do you ride on 42/19? I'm guessing it's something extremely hilly. Most people on here seem to be using about 70", which suggests they either don't ride many steep hills, or they're an awful lot fitter than I am.

I run a 50x18, always have, saves my legs being ripped off at 40mph+ down hills.

now i disagree, i have my free side 2 teeth lower, less spinning on the flat. if i'm too tired to get up a hill, then going a few inch lower aint going to be low enough. most frames are limited to 2 tooth difference (as far as i know) without switching chains.

when i'm tired the spinning is what's knackering

Can't recommend how many inches, other than to expand on J. D. Salinger's quote ("How long should a man's legs be? Long enough to touch the ground. How many gear inches should he choose? Enough to go around.") The following replies, however, need to be addressed:

keep fixie pure

fixed is far better. If you want a freewheel, get gears!

I've read these sentiments many times on many forums. While it's possible to serve up the traditional Your Mileage May Vary or Different Strokes for Different Folks or Whatever Turns Your Cranks rebuttal, agree politely to disagree and keep on keeping on, I don't think an adequate case is often made for freewheeling.

Freewheeling is a beautiful thing:

- It's a way of telling your bike that you're in charge, rather than the other way around.
- It helps you maintain a proper distance from your machine. Aficionados of fixed will say "You feel a true oneness with your bike" -- like that's a good thing. Read The Third Policeman for a chilling reminder that it's not.
- Some people like the sound of the freewheel ticking. I don't (which is why I seek out quiet freewheels), but WTYC.
- It's arguably easier when traffic-jamming in the city, if you're into that sort of thing.
- It's ideal for those of us who don't particularly like to pedal, but love cycling.
- Vive la différence!

Many people have fought and died for your right to freewheel, if I'm reading my history right. The best way to honour their sacrifice is to go your own way.

PS. If they ever pass a law saying single speed has to be fixed, I'm in trouble. All of my bikes are ss/free.

What he said. I don't feel insecure about riding with a freewheel.

When the freewheel was invented and put on the rear hub of a bike, that was progress. a step forward.

Feel free to freewheel, is what I say....
