Low profile lockring
 

I'm running a 13t cog and in need of a new lockring. Any thoughts?

Thanks.

Suntour lockring should work. You can use Phil if it's a Campy hub.

dura ace works too.

i could use a dura ace lockring on my 13 without trouble...

I have Miche hubs. I just bought a formula 1.29 and I couldn't even get it threaded. Do I need Italian ISO threading, but 1.29" ?

I had this problem with my other hubs and we ended up just putting red loctite on it.

Miche hubs take Campy, EAI, Phil and Miche lockrings. Formula lockrings won't work with Miche - you need a 33.5mm × 24 tpi lockring ie Italian threaded).

Formula, Dura-Ace, Suntour etc are all BSA threaded (1.29" x 24 TPI).

See http://www.businesscycles.com/tr-refspec.htm

I can't find anything on EAI's site that says it works with 12t or larger... think it's a safe bet? My chain is hitting my Miche lockring.

A safe bet would be to go see lex at bikes and more. He'll take care of you.

phil wood is the answer. it's not low profile, but the contact part is lower than the part where the wrench grips it... ah hell, i can't describe it, look up a picture. i'm confident it will work.

Have to let others answer whether an EAI is safe.

Phil lockrings have a that nice flange part that means your chain shouldn't contact the lockring. Definitely plenty of clearance with 14t. Expensive lockrings though, nearly 30 USD for one.

Hard to say about the EAI, couldn't find an image of one on a hub to compare it with a Miche.

Heres the Miche lockring, seems a little 'tall'.

I was just at bikes and more half an hour ago when I couldn't get it to thread. All they have are Surly lockrings that wouldn't fit. I found a Formula at Chain Reaction and thought I'd give it a shot. Was only $6 anyway.

I wasn't really looking to spend $30 on a lockring, but I guess I'll have to. I can't ride it like this for too long.

dont underestimate the need for a QUALITY lockring. its the single most underrated and important part in your drive train. dont skimp, but it doesnt have to be the highest quality. ive run formula hubs in multiple applications and ive always gone with a DA cog no proplem. I could have used a formula lockring but DA seems to make more sense.

ive heard enough stories from people who've murdered hub threads from using the wrong lockring or using a cheap one. it keeps your cog on and you safe. dont be cheap in that area.

but...and....also...DA cogs are good but the last one I ran(and i ran it for a good year before changing ratios had stripped off threads, or rather, the threads snapped off. i had 1/2 of the threads which were still effective but the remaining half...gone.

ugh. Phil it is.
