Parts & Accessories

After years of mountain biking with thru-axles with bulky handles that seemed to strike every trailside obstacle, we needed a better option. Our Lightning Bolt-On thru axles offer a high-quality, simple, lightweight alternative to that bulky handle. Available in a range of sizes that fit both front and rear wheels on all types of thru-axle-equipped bikes. - Lightning is Better—Our front and rear Lightning Bolt-On axles offer a stronger, more durable, lower profile, and lighter weight option to replace your stock thru-axles. - Low Profile—No more bulky handles to strike trail obstacles. Aerodynamic design. - Light Weight—Our axles are internally bored to remove unnecessary material without compromising strength. - Easy to install—Our matching front and rear Lightning Bolt-On Axles require only a standard 6mm hex wrench for easy installation and removal. - Better Tolerances—Manufactured in the USA to the tightest tolerances using aerospace materials and CNC manufacturing. No longer will your axle loosen while riding.

Our Trainer Axle is designed to adapt your thru-axle equipped bike to on-wheel trainers, such as a 1up, Blackburn, Cyclops, Kinetic, Tacx, Wahoo, and many others. Our goal is to fit the thru-axle to your bike perfectly to minimize spacers and extra parts, providing a clean, high-performance axle for your bike. Train, warm up, and be race ready and fit for the season. - When it’s time for your race or time to head outside, simply remove your bike from the trainer, remove the drive side axle end and go. Our axle is suitable for use on or off the trainer, indoors or out. - The axle shaft and axle ends are precision CNC-machined from 7075 aluminum and hard-anodized for rugged durability. - No special tools required. Design allows for installation or wheel removal using your standard 5mm hex wrench. - Designed, built, and quality tested in the USA. Proven around the world. Important: Before you order, make sure your specific trainer will accommodate the width of your modern thru-axle-equipped bike. Measure your trainer at the widest setting and measure the outside width of your bike frame. Our the trainer axle ends will extend past your frame on each side.
