ive had the rim since the bike show, and its been fine.
I have the older, 40mm one, and bought it laced up on to an xc from bikedock, its needed a few trueings, but not many.
pros: alows lower tyre pressures.
. gives (imo) a better trye profile
. runs in a koxx lb
. comes in loads of colours
. you can make it look cool by having coloured electrical tape (rim tape) :-"
cons: heavier
. slightly more expensive.
. in some peoples experience, not as strong, but I wouldnt know, as ive never broken a rim :'(
:D
