I've just picked up a freewheel cog off brick lane bikes after they told me it's fine. The mechanic leader said that I should trust him... Anyone think I shouldn't?

Maybe Phil Wood hubs are different but I've always found that freewheel and fixed sprocket threads are the same. It is only the width of the threaded part that are different.
Standard ISO freewheel thread is 1.375" isn't it? Perhaps that's why they say it'll fuck the threads, since yours is 1.370". I don't know if that .005" will damage the threads - now personally I would screw it on by hand and if it feels at all like it's tight or binding, then I wouldn't do it.
I've also heard that some sprockets (EAI specifically) have plating that is thick enough to damage the Phil threads - perhaps that is what they're concerned about.
Could you please recommend me some? They told me that the cogs have to be non plated as it'll damage the threads. They also told me not to use surly or east-asia (i think it's called) cogs as they're too thick. I'm going to bricklane on sunday so I'll probably check it out.

I currently have a Phil wood track hub with only one fixed side, the thread on these are 1.370 x 24 tpi.
What I wanted to do is apply a freewheel cog onto the fixed threads, I've checked out various forums and people say that it's do able however when I sent an email to the customer service over at Phil wood, they said that they absolutely don't recommend doing as the threads will be fucked. I'm not sure who to believe.
I have various options
- man up and ride it fixed for the time being
- Just atleast attempt it, I'm not sure what cog I could use, so if you have any suggestions, please mention.
- Sell the wheel and hub and get a wheel with a flip flop hub. I was contemplating on doing so but I really want to get on my bike asap and ride. Also, I'm not sure how much I could sell my wheel and hub for, it's a **HSON rim with a phill wood hub **which is 5 months old.
What option would be best for me? Note: I have bought a rear brake already, so i'd have to sell that too if i were to opt out of trying.
Thanks

I'm planning on putting a single speed sprocket (19T, 1/8'') on a phil wood fixed hub. I was wondering if I could apply something like this http://www.ebay.co.uk/itm/Single-Speed- ... 674wt_1023 ? Or is the quality too poor ? In which case, would this Surly Single Speed Sprocket be better?
Also would I use this technique to put it on? Mikes Bikes: How to Install a Cassette - YouTube
i.e. Grease hub and threads> screw on sprocket> tighten with freewheel remover tool thingy... done! Am I right?
Thanks

May I ask why you'd want to swap it?

Are you happy with the 46x18 (69") on your old bike? if so that is the gear to go for. As 790 said chainrings on single speed have a pretty easy life but there is no doubt that different brands can vary in hardness. Also they can vary in the degree of "roundness" Some nasty chainrings can cause the chain to run tight and slack because they are slightly elliptical. Impossible to tell in the shop of course.
Just seen this on the Velosolo website
***Token Track Chainset
A new track chainset from Token with traditional square taper fitting. Forged 7075 aluminium alloy arms with 144mm BCD (compatible with Token chainrings only). Complete with 1/8" 48t CNC 'Shuriken' chainring***
I am at a loss to understand how there can be compatability issues on a track chainset if the BCD is right but maybe it would be best to stick with Miche.I'm not comfortable with my current ratio of 46/18, It does become abit of a struggle when I try to stop but I suspect that happens with all fixed gears, I do want to downgrade defiantly but I don't know to what. Does that mean that token is only compatible with the token arms?
Wondering if guys could give me some advice.
I have a philwood track hub and I want to apply a Halo fixed track cog 1/8th, both of them have the same threading but would I need a Halo lockring to go with it? ATM I have a philwood lock ring.
