Giant Propel cracking noise
A friend has a strange problem/issue with his 2016 GIANT PROPEL ADVANCED SL 2. He's not had it long, maybe 600km on it.
Since new, it's made a strange cracking noise. Basically, it clicks (sounds a bit like a slightly out of index rear mech) for a minute or so, then makes quite a loud cracking noise, then is silent. It stays silent for a while, before the process starts again
He took it back to the shop, who muttered something about thinking grease is making it's way out of the rear hub and onto the freehub pawls, causing the freewheel to skip
Personally, I think that's nonsense.
I know swapping out the rear wheel for a reliable one would test the theory, but he hasn't had chance.
He's not a user on these forums, so on his behalf I'm asking for any ideas you think might cause this?? I've yet to actually get my hands on the bike to check it over, but I've ridden next to him while it does it and it is a strange noise indeed and I can't get my head round what's causing it. Thoughts welcome, thanks.

If pedalling and occurring during both in and out of the saddle, I'll take a stab at the press fit bottom bracket wasn't installed properly
Should have mentioned happens whilst pedalling, seems to be ay gear too.
BB installation issue is a good shout. Thanks for the idea

to eliminate remove it, clean it, put some assembly paste on it before refitting
Thanks, but it's an ISP.
Also, compared to noise I've heard from a seat post, its a deeper, bigger, noise. Imagine a really loud crack, basically
