I have no issues at all with crests and various Maxxis wire and folding bead tyres from 2.1 to 2.4in widths. Currently got 2.4in Advantages in there no issues. Can’t say they’re any better or worse for tyres on and off than 717s or similar that I’ve used before.
The crest is pretty damn tough for what it is – I’ve ridden mine pretty hard over the last couple of years in lots of rocky places and there are a couple of non-performance impairing dings in the rear and it now needs a bit of a tweak with a spoke key.
Having said that, I’d go for the Arch EX if I was looking to buy rims now. It’s stiffer and tougher for not a lot more weight. Probably the perfect trail riding compromise.
