CYSKYSingle Chainring Bolts 5 Pack M8 Single Short Chain Ring Bolts Fit for Road Bike, Mountain Bike, BMX, MTB, Fixie

Fair price and worked a treat. It's a thumbs up from me.

Does what it's meant to. Remember to get thread lock at the same time to avoid them loosening

I bought a set of these to replace some missing chainring bolts during an interim period without my power meter on my track bike. Whilst they're pretty well made for the price (and the red looks pretty sweet!) they don't fit track cranks. The nut essentially is too long so that when the nut is screwed in all the way there's still a gap and the chainring isn't tight enough.I'm sure that on other cranksets it may not be an issue but on the Dura Ace Track one they simply don't fit. For the price it's not bad but essentially not useful for the purpose I got them for.

Brilliant, did the job perfectly.

Seemingly well made. Do the job that they're supposed to do, until you find one of the nuts is oversize and won't fit in the hole of the crank set. I initially thought that the hole had grit or grime in it, so cleaned again and gave it a try. Nope, wouldn't fit. Then I assumed one of the holes was undersized and gave it a rub with some emery wrapped around a pencil, nope. Then tried it in every other hole of the bolt pattern and it wouldn't fit either, so out came the measuring calipers. I found the nut to be oversized @10.1mm when all the others and the originals that they were replacing, measured @9.9mm. That .2mm from a CNC machined part is a bit naff to be fair. Not exactly expensive, but still one didn't fit. Luckily I only needed four of the five, otherwise these would of been going back.

Look good but when trying to fix them in two of the Alan key threads broke. They have stayed in place but are now going to be a very difficult to get out if I ever need to.

replaced originals with these, set the torque, no more annoying click from the crank area...

I needed some new chainring bolts, so thought I’d try this due to the good feedback. However, the quality was poor, so soft that it was a struggle to get to the required NM torque without rounding them off. In the end had to drill two out as I couldn’t get the required torque and this has really noisy chainring creaking. Don’t waste your money, go to your LBS and get some quality items.
