Shimano Ultegra 6800 Rear Quick Release

This QR solved a problem I was having with my wheel slipping during use.For a vintage bike rebuild I did a few months back I had to buy a new rear wheel. Many older frames have a horizontal dropout design where the wheel comes forward if the ankle isn't tightened enough, and I was running into a problem that even with the tightest setting I could get the quick release it had a tendency to slip out and misalign the wheel when under heavy loads and high power bursts. Not ideal. But, when I replaced this QR, the problem was solved. 2 major advantages it has over the standard QR it replaced:1. Inner area of the release had more grip: Where it came into contact with the dropouts had more traction2. Mechanism for closing the quick release is more ergonomic: it allows for the release to be closed easier with higher forces, ensuring it was well tight enough.

The threading of the skewer run out after 2 rides. Unsatisfied with the product quality.

Does what it was designed to do - looks authentic - my general concern with any 'branded' products purchased this way - stamping a product falsely does occur more than one would imagine...

I used this on a rear wheel that wouldn’t sit perfectly in the drops. The wheel kept shifting. With my high-quality open-cam skewer, I would close the skewer with so much force that it felt like it was about to snap, yet it still didn’t hold the wheel securely, and the wheel would still shift slightly in the drops mid-ride. However, with this Ultegra closed-cam skewer, the wheel finally stays firmly in the drops, even on gravel, and I can use less force to close it than I did with my other skewers. No more shifting. The issue is resolved. All is good. Color-wise, it doesn’t match my other skewer or anything else about my bike. But that’s quite Ok. Function first, and it functions quite well. Very happy, and it’s great to ride knowing that everything will stay in place. If you need a great skewer, go for this one.

I was surprised when my tire started dragging the frame (didn't know what happened). As old as the original Skewer looked I thought it was time to replace it and that it would be easy to find one. Not the case though, I couldn't find the correct size, however, read a review on this quick release which sounded good.See photo: with the wheel off I measured the frame I.D. and O.D., which showed the skewer will fit nicely with a couple of turns left, and it did clamp down with additional pressure. Also note that I cleaned the mating surfaces with a oil remover solution.
