I thought I'd add an update on mine since we're getting kind of general here. I've been riding my Nashbar build this year so the Denali has been languishing, but I tuned it up today, put some 32 tires on and adjusted it for my 15 year old son. It's a little big for him at 5'7" so he's sitting pretty upright with the saddle all the way down, but we went on a short ride and he did great! Without my eccentric fairing of course.
So, after lasting around 18K miles of daily commuting and light off road use the Denali is now a generational bike having been passed down father to son. Who knows, after some now overdue parts swaps it may last for years and another generation.
