Using a solid 7075-T6 rod rather than a hollow tube makes this the strongest possible rear axle design while still being lighter than a stock 12mm thru axle with integrated lever.
If you already carry the One Up EDC multitool with you, there's no need for the heavy integrated lever which can snag on trail-side obstacles.
