I have a set. I hover around 200 and they're fine for general trail riding, though I'd prefer a wider rim
I picked these up during the sale. I'm riding Alex TD19s now (622 x 19), so the jump to 24mm sounds like a good size for the single track trail riding I do. I also picked up some 2.25 Maxxis Ardent tires, which I thought would be a nice improvement from the 2.1 Aspens on the TD19s.
At 180-185, I figure that'll be a big improvement regardless, but if there's something I'm missing in thinking that will all work well together, feel free to set me straight!
