Lixada MTB Bike QR Adapter 12mm to 9mm Thru Axle Hub Quick Release 100/135/142/148mm Mountain Bicycle Front Wheel Hub Adapter

This was everything I hoped it would do. The stock QR141 rear hub on my Cannondale was absolute trash. And finding a replacement hub or wheel with that same standard axle spacing is near impossible. After doing much research and measuring I decided to take the chance on this simple little conversion axle in a size 148mm. It fits super flush once inserted into the hub and is not noticeable at all. Boost 148x12mm rear hubs are so much more common to find and I wanted a cheap way to convert it to fit QR without spending money on more expensive hubs like Hope or DT Swiss. This did the trick and I highly recommend this product to anyone looking to find an easy way to upgrade their QR141 wheels

This is very well made and fits perfect for my bike.

Not much to say other then it does exactly what I needed it to do. Convert 12x148 to QR 9mm skewer

I was skeptical of the reviews that said it'd make any Boost 148 wheel work with QR141. The concept makes sense, but the math does not but I figured I'd try it anyway. Unsurprisingly, the axle itself is wider than the dropouts on my Trek Roscoe by 7mm (not to mention that a Boost hub is also wider by the same 7mm by design). The quality of the axle itself is fine but it simply doesn't work for QR141.

Wrong fit. To big to fit my 26 x4 front rim ael
