I just got a batch of Shimano 11 speed road cassettes at the machine shop modified to fit a common 8/9/10 hub. I have 5 105 (CS-5800) and 5 Ultegra (CS-6800) cassettes. All are 11-32T. These will fit on the most common freehub body in the world, the Shimano 8/9/10 hub.

I will ship these for free within the US. If you're located outside of the Continental US, you just pay whatever any amount over $6. These are all brand new and all work great.
