Cog question

I've just built a rear wheel on a Phil track hub, and now I need to get a cog on there. The nearest thread to the hub, which the cog sits on, looks like it will be wider than a cog to me. Are these things fatter than they look on the internet, or do you have to add spacers? I'm going to go for a Phil cog, to match, me thinks.

Phil hub + phil sproket + phil lockring = all good

Problem solved, cheers gizmond.

Do all lockrings do up with the same tool? Any recommendations?

dura ace tool from hubjub

I've got the hozan one from hubjub, works for me.

get the normal shimano chainwhip instead of above dura-ace (i have the dura-ace, but prefer the normal one)

this is the dura-ace

A "normal" Shimano chainwhip is only good for 3/32" cogs. If you run 1/4" you better be sure you have got the right tool.

Damn when did they start doing 1/4th drive train? What would be some big ass bits, motorbike chain anyone?

1/8th is what your after (unless its not)

change the chain, wow, really hard

I agree with the above, apologies. I have always had difficulty with this concept of 1/8" chain. Er, four eights are thirty-two.

That said, I think my point about chain whips is still correct. I have two, one of which doesn't fit the fixie.

Change the chain, the chainring and the cog if you want. But a narrow chain whip still won't fit a wide cog.

chain on the chainwhip, they have a slip pin ;)

Too slow

Too slow

Let me have a long careful think for a moment ...

Nope, having thought carefully, I don't think I have ever heard a more ballsaching way of proceeding than to swap the chain on a chainwhip back and forth depending on whether it is a 3/32 or 1/4 cog.

Do you use just the one set of spokes for all your bikes as well?

That'll be a 1/8" cog, of course.

Oh dear, this thread is now terminating at platform 2.

'Too slow' was an edit direct at dogs, I posted the same thing he wrote.

An 1/8th wip will fit an 1/8th sproket and a 3/32nd sproket, although probably not one of your 1/4 sprokets

Right, so a 1/8" chain whip it is then? And a lock-ring tool? The Dura-Ace one looks like it has one built in, which is handy. So, what are the two chain lengths for? How do you crank it on? Once the cog is on tight, then you just slip the lock-ring on and tighten the hell out of it, right? Should I grease everything before I fit it?

get the one i posted from chainreaction, wrap chain around sprocket and get ready for scraping your knuckles and swearing for a while.

i made my own chainwhip.

Old chain, jammed in a claw hammer, easy and free.
