I have a Ritchey chainset with 4 bolt fixing. Does anyone know what rings are compatible with it as I would like a good replacement middle ring to use the cranks for a single speed project.

thanks

Sure it's not 5 bolts? So a 5 arm chainset.
Could be Compact or Standard. Would need pics or you to measure either distance between two adjacent holes or a hole to bottom bracket axle (all centre/centre style)

Oh the '5th' arm is behind/is the crank arm.

Else is some modern thing.

That's modern talk :lol: 4-arm's

Get yer sen in the 98+ section.

Grab and nice single speed chainring, should be plenty around as that's an everyday 'of the day' size

Look for none ramped, none profiled rings. Probably come under the SS or Downhill naming
e.g. Hope SS/DH http://www.chainreactioncycles.com/Mode ... elID=80578
or E13 http://www.chainreactioncycles.com/Mode ... elID=55190

I've got some DMR stuff here and a stash of 4-arm outer and middle I'll have a look through.
But what tooth count are you after ?

Something non-ramped and fairly thick with high teeth. Something like the E13, hope or Renthal. The cheapest good looking one is this:

Not saying you can't use cheaper, it's just that you don't really want to put a triple chainring on as they tend to flex too much and can have ramps, pins and shift gates that let the chain derail too easily. Buy cheap, buy twice!

You can also get some coloured singlespeed rings from Salsa
