Bicycle Thru Axle refers to a form of bicycle center axle design that features a center axle with a core that passes directly through the five-way portion of the frame, with no additional bearings or washers. This design allows for a cleaner center shaft that reduces friction and weight, and is typically used in higher-end models of road and mountain bikes.
There are several types of barrel shaft levers, including one-piece handle barrel shafts, handleless barrel shafts, and hidden handle barrel shafts:
One-piece handle barrel shaft: the handle and shaft are one piece, making it easy to remove, but the overall weight is higher.
Handleless Barrel Shaft: The handle and barrel shaft rod are separate, and the handle is usually a 6mm Allen wrench or a set of Allen combination tools. This design can reduce the weight of the car and the appearance is more beautiful, but you need to carry the relevant tools to disassemble the wheelset. An example is the Titanium Thru Axle from Titour.
Hidden Handle Barrel Axle: The handle is hidden in the axle center and axle head, which is both aesthetically pleasing and practical, but the replacement cost is higher.
Titanium Bicycle Thru Axle is made of TianiumGR5 Ti-6Al-4V. Due to the use of aerospace materials and fine processing, it becomes the lightest and highest quality barrel axle on the market.
