That happened to me. But i'd not even ridden it. Built it up, left it above an old CRT monitor for a couple of days. Pop. Bits of hub side wall scattered over the room.
Contacted Hope, they said its because I'd radially laced it.
yep, same story here - I was expecting Hope to give me a replacement and investigate the failure.....
I've since switched my allegiances from Hope to Goldtec!
I once got in on a cold night, propped my bike near a radiator and the hub flange cracked.
(Hope mono, radial laced)
Radiator are death
