Cyclists and bike mechanics, these Forest Byke crank nuts are exactly what you need for maintaining or repairing your bike's bottom bracket. This set includes 2 standard M8 nuts with 14mm hex heads that fit most square taper bottom brackets perfectly. The black finish looks clean and resists corrosion, so they won't rust out on you. Installation is straightforward - just make sure your crank arms aren't worn out before putting these on. These are essential replacement parts whether you're doing routine maintenance, building up a new bike, or fixing an old one. The quality is solid and they thread on smoothly without cross-threading issues. At this price for a pair, it's smart to keep some extras in your toolbox for future repairs. Much better than trying to reuse old, worn-out nuts that might not hold torque properly. If you're working on mountain bikes, road bikes, or pretty much any bicycle with square taper cranks, these are the genuine replacement parts you need. Just remember to torque them properly and check your crank arms for wear while you're at it - safety first when it comes to bike components!
