I bought from price point the 2014 version of this killers for $900 and i have to say that they worth any single penny. The Mavic's SLR are super light and super strong. I mounted them on my 2014 Specialized Rockhopper Comp and simply turned a bike in fast downhill rocket. Buy them with confidence. You will never regret it!!!

After a ton of research, I chose these wheels to replace the stock wheel-set that came with my carbon hardtail 29er. My SLR's weighed in at 1628 g with QR adapters front and rear (not including skewers). Fast to accelerate and quick rear engagement. No noticeable flex for a lightweight wheel-set. Continental tires mounted tubeless on first try and have held air pressure for over two weeks. Very happy with the look and performance.
