Davidwrote a review of Mercury Wheels M1 Disc Brake Wheelset - Clincher on August 11, 2017
Familiarity: I've used it once or twice and have initial impressions
First, you can't beat the price point for a wheel as versatile as these. I put these on a CX bike with 15mm / 12mm TA front/back. I ignored the description around tire size and put some Schwalbe G1's in 35mm on. Took the bike for a ~40mile gravel / road ride and they worked out perfect. They worked every bit as well as some custom wheels I own which I paid a lot more for, and from what I can tell they are very close in weight also. Add to that the great service at Comp Cyclist, where they called to let me know the order was shipping, and a follow up call to see if I had any questions. I agree with the reviewers comment re: rim tape, however that was a quick fix. Thumbs up so far!
