Another question for you gurus...tronracer

Can any hub be made fixed with a lock ring? I saw some high flange hubs on ebay, but it doesn't say track. Can I make it fixed if it isn't?
If it has threads, it it can be either.......Dave Hickey

You either thread on a track cog(fixed) or a BMX freewheel(single speed)

not sure if this is what your asking, but....

the lock-ring doesnt make the fixie; the fact that there's no freewheel makes it a fixie,

if you thread a track cog onto a freewheel-hub (such as a bmx hub or an older road hub [i.e., one that doesnt accommodate a lockring]) it will work fine.

One word of caution... it is POSSIBLE to accidently unthread the cog if leg-braking, so many people use loc-tite when installing the cog. In 10 years of fixie riding (on freewheel hubs) ive never unscrewed a cog.
In a perfect world, you'd have a fixed hubGinz

If you were starting with an old set of hubs from the parts bin, the loc-tite would probably do ok. But, it sounds like you are starting from scratch, so why not find a set of real fixed gear hubs.

If you don't want to spend a ton, check out the Suzue Basic and Surly "New" Fixed.
There is a difference ...Humma Hah

Track hubs have a second, slightly smaller, reverse-threaded section outside the threads that the cog screws on to. That smaller section holds the locking ring.

Our guru, Sheldon Brown, sez it IS possible to screw a track cog on a non-lockring hub, but use with caution. Apply thread locking compound, tighten like heck, and avoid heavy backpedal forces.

I'd have to say that's OK for a beater hub, but I'd not trash a primo new hub that way -- that kind of abuse is likely to gall the threads in short order, making it hard to swap cogs. Better to get the right type.

i wasnt trying to imply a track hub isnt different from a freewheel hub...i was merely trying to state that a track hub isnt 'necessary' for a fixie.

trust me, putting a track cog on a freewheel hub is not goint to 'trash' it; nor is it abuse. Ive been doing it for 10 years w/out problems.

Also, in my experience, heavy backpedaling (as opposed to skidding) will not loosen the cog. IN MY EXPERIENCE. I acknolwged the fact that it theoretically could in my above post, but personally, i wouldnt (and dont) worry about it.

Sort of just went through the same deal. I got the Suzue basic track hub. Then I could get the sprockets locally cheaper than Harris Cyclery. Well they are in the mail somewhere and they were not cheap. A DA track cog is $20-$22 and the BMX free is $16-$18. The lock ring was recommended for safety reasons and I being new to the fix world was not going to balk at the suggestion. The track hubs on the fix side are 2 stage threading, large for the cog, smaller for the lockring. The free side is single threaded.

Picked up a 16 tooth Surly cog from Excel for pretty reasonable money. Problem with ordering from a catalog is that with shipping it's never "worth it" to buy just 1 inexpensive article. I have to throw a few more things into the order to "justify" the shipping.

I'd imagine you know how that goes.
Coudlve had your LBS order it. No shipping.SteveO

I can get surly cogs cheaper at my LBS than net+shipping direct.
Better to ask the shop than just assume, imo.

Not a real bike store, a neighborhood garage shop. $16 DA track cog, $16 for a claws bmx freewheel.

I am a recent convert to the (admittedly small) fixed-gear-is-best-with-a-track-hub camp. I had a track cog/freewheel hub combo come unscrewed on me and drop the chain at 30+ mph. Scary!!!!

Moral: run a front brake if you ride on the road.

It is ACTUALLY (not just theoretically) possible to unscrew a track cog from the hub with back-pedal pressure.

I just got a built wheel Suzue high-flange flip flop hub, Mavic MA4 and proper lockring w/ actual track nuts from QBP through my LBS for < $150 soooo worth it.

Now if I can just get that pucker out of the saddle.

were you running a brake at the time? just curious.
I BElieVE!!GTDave
Jul 18, 2002 11:06 AM
Yep, I BELIEVE!!! in brakes (can I get an amen)

truth be told, I paid more for the wheel than for the two bikes that I Frankensteined together to make the fixie.
How about the ultimate fixie/single speedDave Hickey

File this under "if I won the Lottery".

Call Craig Calfee and have him build a Dragonfly with track dropouts and no shift bosses. Lace Chris King single speed hubs to Zipp 303's. Throw in a cinelli ram bar/stem and FSA carbon cranks witha 42t ring. If figure for about $4500, you could have the ultimate fixie/singlespeed.

Yeah, that would be decadent-sweet, and worth about a dozen of my Trek/Peugeout conglomeration.

I felt like I was breaking some sort of unwritten cool dude/bike messenger/grunge rock/dreadlock/sanfordandson/urbantrafficsurfingwarrior ethic when I bought the wheel, but

1. I could have been pretty seriously hurt
2. The way I see it, on a fixie, the rear wheel's the thing. It's both the stop part and the go part. If money needs to be spent on it, this is where to spend it
3. $150 really is not That much money (in the bicycle scheme of things)
4. The battle cry of fat rich dudes on litespeeds everywhere...Its My Money! (yeah I know this is a provocation) It's a joke son...a joke I say

that boy's about as subtle as a hand gernade in a barrel of oatmeal ;)

I'd chose track dropouts only for a track bike ...Humma Hah

... they look like a real pain for fixing flats on the roadside. I see no way to remove the wheel without breaking the chain.

Old-fashioned horizontal dropouts for me. But otherwise, I like your idea. In that price range, the custom ride that caught my eye was a "Moon", royal blue with gold-plated headset, forks, stays, etc.
