Saiper 10pcs Double Chainring Bolts M8 Chain Ring Bolts for Road Bike, Mountain Bike, BMX, MTB Crankset

Works decent

Received 10 sets as promised, good value for that amount they come with branding not shown in photos, but fit and finish is good for the price. #5 Allen (hex) for the front side, flathead for the rear. Put anti-seize on the threads when you install them or you’ll be drilling them out years later

Lots of different size chain rings on e-bikes. Measure first if you don’t feel like ordering two or three sizes like I did lol.

Installed easily. I needed to change out bottom bracket from a Shimano Octalink to a square bolt type but that was easy enough to do. My knees are now happier with the shorter crank arm length.My only complaint was that arrived having partially come loose from its cardboard backing but it’s a strong piece of metal so no problems.

Very lightweight. The fit is perfect. Just be careful when applying torque. They are alumunum, not stailess steel.

They claim they send 2 size nuts for single speed chain rings received only 7mm nuts for multi speed. Not a big deal for me but I dont not suggest if you need 5mm nuts

Pictured is 10 sets. This is a scam. You will receive 5 sets for twice the price.

Only got 5
