Nukeproof Thru Axle Front 15mmThis thru-axle is designed as a direct replacement for the standard thru-axles found in 15mm Rockshox Boost forks as well as most models of 15mm Boost Fox forks. It features a high-quality 7075 aluminium build, which makes it not only lightweight but also very strong and durable on your mountain bike (MTB). This makes it a great choice of upgrade for riders who need to replace their damaged or lost stock axle on their forks.The axle has a washer which helps reduce pressure on the fork legs and transfers some of the tightening torque to the clamping load. This also helps to increase stiffness, while preventing the axle from getting stuck when you want to remove it.All axles are a 6mm hex on the non-drive side and have a backup 6mm hex on the drive-side, allowing the axle to be tightened and loosened from either side of the bike.Always apply a small amount of grease to the axle and threads when installing your axle.
