Fiberin AD-M27-SL XC 29er

Over the past couple of years, I have purchased 4 of these 280 gram rims and built up 2 sets of wheels on 142 hubs, and a set on 148 hubs. These are 27mm wide, and 25mm deep. I run these rims on my Carbon Hardtail, and the wheelset weighs just under 1380grams, with sealing tape. On my Hardtail, I always run 2.0 / 50mm lightweight gravel/bikepacking tires. I have close to 3K of hard rough terrain miles on these wheels without issue. (I did check/re-tension the rear wheel once after a couple of years of riding.) I built up a set of gravel wheels with 142 hubs that clocks in around 1300 grams with tape. I have a little over 1000 miles on this wheel set. I run 40mm on the back and 42mm tires on the front.
