So I picked these up for a full suspension 27.5 build I'm doing for my wife ((Morewood Zula, 100 rear travel 120 front, got a great deal on a NIB a few years old) and trying to keep the costs down. Overall these are very nice wheels which needed a bit of effort to set up. As DM said below, these are labeled as Easton rims, not Race Face...same company, different stickers. No big deal for me. They came taped for tubeless, which was a nice surprise, but the tape was not stuck down well. I put tubes in them at 40 psi for 24 hours and the tape went down perfectly. Got some Maxxis TRL tires to seat without sealant using just a floor pump and they held pretty well overnight, rear got a bit soft. Topped them up with Stans and they are holding air perfectly.
There have been some so-so reviews for some very similarly built wheels (Easton ARC laced to DT Swiss 350) that were spec'ed on Santa Cruz bikes last year (maybe two years ago), several went out of true very quickly. For that reason, I threw these on my stand, and with an inflated tire the tension was pretty low (drive side 900 N when the rim maxes out at 1200 N) so I brought them up tension. I ride the 29 inch version of these rims (ARC 27) that I built to DT Swiss 240 hubs, and I've had no trouble with them staying true. I weight 220 without gear and I live in a rocky area, so I run them on my Ibis Ripley a bit firmer than some (28ish rear, 25 front) and I've had no issues with dents. My wife is well under 130, and I figure these should last very nicely for her use.
The stickers are not very durable on these rims, but for ridable wheels on sale for $280, These seem great, I'll update if anything changes.
