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? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

What cog measurement would be best for a 46T crank wheel?

Frame: 46 cm
Wheelset: 650c
Crank wheel: 46T

So, my crank wheel has been measured at 46T and I'm trying to determine how what cog I should order for my fixed gear. 14T, 16T, or 18T?

I heard a 14T would be an easier ride, so to speak. I want a smooth easy ride.

Yet another one of my friends told me that I was being told backwards?

Also, any ideas on what would be best for a free-wheel?

I know that this is strictly specific to the rider, some might be too easy, too hard, or just right. It's a trial and error thing. But honestly all of my friends ride huge bikes. 52 cm + and I'm on a 46 cm frame so I can't test ride their bikes comfortably...

I would recommend you start out with about 70 gear inches and see if you like it. That would be a 17T cog for you.

16t would give you 70 inches. 17t would give you 65 inches. i would suggest the 17t.

your friend was right. larger chainring=higher gear, smaller cog=higher gear.

whoever told you 14 would be easier was wrong.

Best is relative to what kind of shape you're in, and what kind of terrain you're riding on. I've been running 46/18 for awhile, and have been happy with that. May try a 17 or 16 in the near future, too

It really depends on you. I find 48x16 (78.8 gi) to be pretty ideal for most situations. For a lot of folks that's way too steep, and others prefer something bigger.

A 17 cog will get you 17 skid patches, so go with that.

Could be variations in tire size. Or "tyre", since you lot can't be bothered to spell it correctly.

According to mine:
46x17 on a 700x23 tyre = 71.1 inches.
46x16 on a 700x23 tyre = 75.6 inches
adriano is correct. because he paid attention to the wheel size the OP is using.

Sorry, apologies. Missed the 650. Duh!

for a smooth ride, I'd go 65-70 gear inches.

It's spelt tyre over here.
