The Cham is just the bike I've been wanting for ages TBH. I genuinely don't think I'm massively slower on it on the downs than the Helius. It's stiff, but talk of "Like being fisted by Joe Calzhage, and Joe's still got his glove on" is way off the mark, did 5 hours in Wales couple of weeks back It it was cool.
Thors...Dunno really, seem bomb proof, like the stiffness, but set-up time has been endless, after 5 months just about got there with pretty much constant "3 psi in, 1 out" kind of gig. Don't trust them if I'm honest after the lowers cracked.
