What particular trail? presuming around Wellington? Would be keen to have a look
I ride single blacks (grade 5) and the occasional double black (6) on my Rail at the chch adventure park. Never really paid attention to what grade the bike was built for :ROFLMAO:
No offence but any crack (like the many on this topic) in a frame is a structural issue. In some cases filler has cracked in other cases the frame has cracked right through.
Let's hope Giant has learnt some lessons for the 2023 Reigns and Trances
For anyone interested in NZ, they are up on the Giant website E+2 and 3 only with NZ RRP.

Delivery dates end of February
because that’s what it says on the Giant Australia website. In hindsight that maybe just the TRX wheelset. Under hubs on the bike it just says Giant TRX hubs
I'd be asking for money back as the bike is not fit for purpose and start looking at another brand..
Keeping in mind you originally posted you only rode it for two weeks from new and its been at the shop for 7 months now. Under NZ law you'd easily get your money back.
