Probably about to buy a set of the 33mm hookless, they’re pretty unequivocal about it, makes a stronger rim with no drawbacks apparently.
“For hookless, it is will be much stronger, because the outer layer can go to the rim bed, to make the rim wall sides much stronger.
For the old rims with hook, the outer layer is only reaching at the top of bead, can not go in to rim bed.”
Sounds good to me- I don’t think you can order the hookless from the website so waiting for one of the Nancys to get back to me with details.
I’ve got one of the old-process “wider” 26 rims on the back of my hardtail, tbh it’s had very little use so far but it’s not exploded and fired carbon splinters through my heart…
