These slightly shorter screws are needed if you want to screw monoblades like those from Garbaruk onto a classic crank spider that previously had a double combination installed.
At the front it has a 5 mm Allen key, at the rear you ideally use a chainring wrench to hold it in place.
Made of 7075 aluminum, set of 5 in black anodized.
Made in China
