Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer?

Quick question.

Quick question.

My chain ring is 40 teeth & the rear is 15. What size chain should I be using? I can't figure it out.

So would 1/2x1/8 work? Sorry I don't know much about this.

It's either a 1/8 or 3/32. They are the dominant types.
The former usually on track bikes and the latter on road bikes with derailleurs.

If the 1/8 doesnt fit, it's the 3/32, and vice versa.
Although 90% of fixed-gears are 1/8.

Next time, you can consult Sheldon for all the answers.

Peace.

The number of teeth on your chainring and cog doesn't matter, although most 15T cogs are probably 1/8".

Thanks for the help everyone. It's technically not a fixed gear, I took the gears off my bike since it's older and they weren't working right. It kept causing my chain to slip so I decided to get rid of them. I'm thinking I should try using 3/32. I plan on getting a single hub eventually though.

You're having a hangover?

To the OP: a 1/8" chain will always fit. If in doubt, get a 1/8" chain and you'll be fine.

Alright so I got it figured out. Ended up using 3/32 and took some links out. Works like a charm.

So I've been fooling around with my rear brake and been having trouble. Probably because I was using spare parts, so I'm wondering how much it would be to take it to a shop and just have them set it up for me instead? Any info is much appreciated.

Does your rear wheel have a steel (as opposed to aluminum) rim?

Your brake cable is too short, needs a bit of slack in it. Are the brake pads new? Kool Stop pads, the grey or salmon ones, work quite well. If your rims are steel, allow more time for braking, especially in the rain. Since you are running the bike singlespeed, I'd get a front brake as it will provide the best stopping power by far.

I am aware that there are plenty of 3/32" 15T cogs. That's why I said most, rather than all.

Please don't be needlessly snarky.
