🔩 CYSKY Single Chainring Bolts 5 Pack - M8 Single Short Chain Ring Bolts for Road Bike, Mountain Bike, BMX, MTB, Fixie - Aluminum Alloy, CNC in Black/Blue/Red Review

You failed me today. They all collapsed just meters from my front door. 6 miles. what if it had happened earlier. Aaaargh! NO!

Excellent product, made with quality materials, accurate description, good price and lightning fast delivery. I highly recommend this supplier and their products.

They're cheap, easy to remove and shorter than the standard screws they replace. However, they do their job. Luckily there were 5 packs when I needed 4 so the one I picked off didn't delay my build.

I change the sprockets at least 3 times a month. It's been almost a year and they're still holding on. No indication that they will break when I tighten them. Only use a torque wrench and be careful not to twist them. So they will probably last forever. Update July 3, 2021: With ftp 360w and almost a year later they are still going strong. If you use a torque wrench, you cannot tighten and remove them. Another 5⭐ from me.

This is listed as an M8 bolt which means the threaded shank must be 8mm OD. However, the description says the HEAD of the screw is 8mm in diameter. I asked a question about this but the answer didn't confirm whether the threaded shank diameter is 8mm or not. I took a chance and found that the threaded shank (not the head) is IS M8 and the product and delivery was good. The list could be clearer, otherwise very satisfied.
