Spur of the moment...
So, I take the bike in to
Bike Culture, fully intending to get the post repaired...
... walked out of there with a KS LEV on the bike instead (and a significantly lighter wallet).
Just got back from about 3 hours on the trails (including K2 and Corners - we did lots of climbing), it's ace. Smoother than the Reverb, although I need to slow it down a touch, as I'm having trouble hitting that 1/3 drop that I like for a lot of the not-so-steep trails.
Buyer's regret? Yes, but it will lessen when I get home and sell both of my Reverbs (1 non-stealth in A1 condition, 1 stealth in need of repair).
