I’ve had Trace Enduros on for about 9 months now. Built by me on Pro 2s. They build a very stiff wheel for the weight due to the offset spoke bead which is very good. I’ve also built a number of pairs for customers and haven’t had any back.
Their weight is very good for their width but sadly that seems to possibly come at a bit of a price. They seem to be rather susceptible to dings. I completely ruined my rear one at the Ard Rock last year hitting a rock. Bent the rim so far that there was a gap between the tyre bead and the rim bead.
Saying that, I have no proof that that incident wouldn’t have destroyed any other rim.
I re-rimmed the rear with another and it has been fine so maybe not too bad.
I cut my broken one into bits to compare the cross section with a Flow EX and due to them being pretty much the same weight, the narrower Flow is clearly thicker around the sidewalls which must give it more ding protection. The positioning of the inner rib of the Trace also looks like it might contribute to dings
In conclusion, they’re ok but not great. I’d prefer them to be 30g or so heavier and more resistant to dinging.
