The older Easton/Race Face ARC rims dent like they’re made out of cheese. The new ARC Offset are made out of a different alloy that they say is stronger. I have an ARC Offset 25 but haven’t really put it through the paces yet, so we’ll see.
I ran Stans Flow and Arch MK3 last year and both have been pretty good but like to crack at the eyelets if spokes are over-tensioned (doesn’t seem to take much).
This is going back a few years, but I’ve been happiest with Stans Flow EX and WTB i23. Both of these rims worked well without much fuss. The Flow EX3 looks like a good idea for a rear wheel, but man is it heavy.
If I were shopping for wheels, I’d take a good look at We Are One Movement wheels. You get Agent or Insider rims on i9 101 hubs for $1275 CAD. WAO has some new rims out and these are the old ones, but the price is comparable with a set of high-end alloy wheels, and there’s a lifetime warranty and a track record of people riding them hard over the past couple of seasons without issue.
