eggbeating a lot faster than a 48/16 gearing or is this the same, or what I have currently setup...a 52/18. Will there be that much different, just asking before I go out and purchase a freewheel. Thanks

32x14 is perfect for transporting a little person.

I run 32x15 on my SS mtb around the city, and it's aggravatingly slow.

Furthermore, it's a hair too difficult for a lot of off-road riding, so 32x15 gets a "thumbs down" from me.

Wouldn't wheel diameter be a factor? It is with Sheldon Brown's gear calculator. Maybe that table is for one specific wheel diameter.

This table assumes Sheldon's "27-inch nominal" or a 700x32 tire.

i actually find that using simple gain ratios is a far more convenient and helpful way of determining the similarities and differences between drivetrain setups. since most of us run wheels in the 700x23-25 range, wheel diameter is a bit of an unncessary variable. if you are going to go that far, you should also include crank length.

Hey quick question here regarding the OP's plan... Is he sure that a 14T freewheel will fit his current hub if it has a 16T or 18T on it currently? Aren't the 14Ts a metric thread for a specific hub?

Oh, c'mon. Who the hell would run anything besides 700x19-25 or so? That'd be as "effing ********" as running a back brake.

I dunno, back brakes on geared bikes are somewhat ********.

Either way, I ran into a bum the other day riding a fuji track. I was standing on the corner, leaning on my bike, smoking a cigarette (I've since quit--10 days!) He says: "Is that a track bike." I say, "yeah, sorta.......is that a BACK BRAKE you got on that fix?"

(he had a back brake on his bike, with the lever on the left side)

he says "yeah. for emergencies, you know." he seems a bit sheepish about having a brake on his bike. maybe he didn't notice mine (on the front, of course).

I say 'ah-ite"

he says 'ah-ite'

he rides off.

Good catch... I forgot he was looking for a freewheel. 14T freewheels do take a different threading than 16T freewheels. 15T and smaller ones thread onto the other side of a BMX hub, the side that isn't compatible with track cogs and big freewheels.

If you want a 14t freewheel, you'll have to get a new hub. Your best bet is probably to get a used wheel built around a shimano freehub, and then put on the appropriately sized cassette cog. Or you could just get a bigger chainring.

Man, track bikes are getting cheap enough that bums can afford them?

Good advice, It's always good to ask the exprienced. I might just stick with a 16T freewheel. Thanks
