    SS Chainring for 3-arm FSA Afterburner Crankset

    So, I have a 3-arm FSA Afterburner crankset that I have made SS... the existing small (30T) chainring is OK for now, but I will definitely want to go with a SS specific chainring pretty soon...

    Any recommendations?

    any issues with SSing 3-arm cranksets?

    Proprietary standard components are a singlespeeder's worst enemy.

    Besides the fact that three bolts taking the full load of pedaling torque, the proprietary BCD is the downfall.

    I've never seen an aftermarket ring for the FSA 3-bolt pattern, so I'd suggest rotating the chainring and tweaking the bolt tightening pattern to try to eliminate your high/low tension variance, then just run a tad bit more tension than you would with a proper SS drivetrain. You shouldn't have any issues, but there will always be a possibility of throwing the chain.

    Hmmmm.. or just swap out the crankset...

    Thanks for the reply folks, kinda confirms what I was suspecting... that with a 3 bolt chainring I'm stuck with standard chainrings.

    Pretty much, too bad that's how it ends up. :/

    But in the end, you could hopefully recoup enough from selling the FSA crank to set yourself up with a decent 104 BCD crank.

    Best of luck, and let us know how it pans out!

    Hmmm... Warhawk... looks like a possibility!

    Looks beefy enough too!

    anybody else out there have opinions on the use of 3-bolt chainrings for singlespeed...

    My opinion is that usually us singlespeeders overestimate by a little bit how much torque we are putting on chainrings, chains etc... I mean geared riders stand up int he cranks too... I think we may exert a little more force, but not enough that I think a 3-bolt pattern is a problem, but I am curious if anyone has had a problem with this before?

    YEah, Warhawk offers a TI version as well... figured I'd try the Al version, see how it all jives, and then invest in TI if it works out.

    Any other options for the fsa 3 bolt cranks? I am converting my el mariachi 3 now and have a wheel, hub, and rear cog setup from an el mar SS. Not finding a whole lot of options for my stock fsa comet cranks with a standard 2x setup. I like the crank and bottom bracket as it has taken everything I have thrown at it geared and wanted to keep it. Is warhawk the only one making a 32 tooth 3 bolt? Also could I get decent gearing with either of my current rings on my 2x setup which is a 27/39?

    It looks like FSA is now offering a single ring version of the afterburner specifically for 1x11. Any word on if they will offer just the 386 ring?

    I received an email response back from FSA. they said that it will be available late winter and that they are calling the chain ring "megatooth".
