So i bought a

2011 Dawes SST AL

Only came with a 17T Freewheel (1/8)

Specification:


I bought a COG & Lockring for it but not sure if it will fit, bike comes tomorrow.

It was 1/8 so i pretty much bought a lockring and cog that was "1/8".

COG: Eighth-Inch brand Track Cog 1/8" width CNC Steel with ED treatment
BC 1.37x24 TPI (Standard)
Lockring: Shimano Dura-Ace Track Cog Lockring Left-hand Thread
BC 1.29x24 TPI




*Will they fit on my bike?

Thanks

Not sure what the question is, but that will fit on your bike.

ah, how will they fit? the sizes are different aren't they?

Still unsure of what you're talking about but my guess is that your confused because the threaded part of the lockring is smaller in diameter than that on the cog. This is normal, as there are two individual sets of threads on a fixed hub - a bigger one for the cog and a smaller (reverse threaded) one for the lockring a shown here:



Please have them properly installed at your local shop when your bike arrives.

I'm with Shrodzilla, if you don't know how to properly place a gear on a bike, or can't figure it out, it's a good idea to have a possessional do it.

oh, the cog's diameter on there is larger, i see now.

sorry, i didn't know, thought both were the same size.

Thanks for clearing this up for me.

So helpful!
