Hi Guys!

im a clyde and i love my singlespeed. problem is my chainring bolts keep coming loose. it must be the enormous amount of power im generating!

okay okay, i gotta lay off the krispy kremes...

in any case cabrider's got the same problem (the bolts not the donuts) so it aint just me.

how do i keep em tight? thread loc? is super-glue too extreme?

I've not had any luck with superglue (on anything!).

Clean the bolt threads VERY good with denatured alcohol or similar, and apply a dab of BLUE locktite....let it set up for a day, and you're good to go!

Besides the blue Loctite, check to make sure that there are enough threads engaging betwixt the bolt and nut (which could happen with a thick bashring and inappropriately sized bolts). A couple of weeks ago I used a Spicer Cog Adapter and too-short bolts and by the end of the ride only one was remaining.

Also, I'd highly recommend using steel bolts and nuts only. The alloy ones are for the birds... really light, non-heavy-handed birds that are always keeping a close eye on their equipment This excludes me.

or!

use washers! and that wee tool for grabbing the female bit...

yup

Trust that you're already using a $3 tool such as this to tighten up the bolts?

faaaaaaaascinating

so thats how it looks like. ill look for one of those but i dont that they have one in my neck of the woods... the only person i know who owns one bought his in Hongkong...

And bear in mind that you will probably have to take a file to the tool in order to even make it work effectively.

Might be necessary to take the file to the chainring bolts too in order that they can actually tighten, rather than just bottom out before they're snug.

cherrybomber, that's a $3 tool from Nashbar. No need to go hunting all over town for one - just get it delivered to your doorstep.

thanks man.. problem is shipping to the philippines will probably cost more than tool

I think my bike shop gave me one (maybe for a buck or two) just so I'd stop coming in and bugging them to use thiers. Its a certified shimano tool too.

Hoy tabachoy, use some of that Pinoy ingenuity Something I've used in a pinch is needlenose pliers to hold the nut. Just stick the tips of the pliers into the notches of the nut. Also, make sure the bolt is greased properly.

Well, say buh-bye to the betlogs! If a few scratches on the back of a chainring bolt bother you...

Here's what I've seen three times before: you're on a ride and the chainring bolts slowly fall out until the chainring is held in place by only two bolts, but you don't know it. You stand up to crank on a steepish hill. The ring folds like a taco. Your body rushes forward. You sense immediate, blinding pain in your nether regions. You scream "aray!" and black out. You wake up as a friend sprays their waterbottle on your face. They're all laughing. You walk the three miles back to the car with your head hung low because the drivetrain no longer works, but more importantly, you can't sit on a bike seat for the next couple of days.

BTW, I used to use alloy chainring bolts all the time, until I got into singlespeeding. As I experimented with different chainrings and replaced old ones, the alloy bolts rounded out and the nuts stripped way too easily. Steel bolts aren't as pretty, but you can really crank down on them, and you will never have to bust out your Dremel and cutting wheel to chop through the chainring and bolts because they've stripped.

salamat Drevil!

Will bug the LBS for steel chainring bolts - I think that's the simplest solution, since Dremel-work can be a hit or miss thing.
