I always wanted a Beast of the East! I loved that bike. Prolly one of the first FRHT's
OP: It depends on how fast you wanna go and how rough your terrain is. (as stated) I'm really wishing I had a dually trail bike now b/c my new town has some pretty rough trails. Not all buffed out like my old regular trail. I do just fine on my hardtail, but I would be able to sit down and keep the power on a bit more and spin through some stuff that I currently have to stand and English my way through. Granted, my front suspended hardtail is 10x better than riding these trails on my rigid bike, but if my dually weren't such a pig beast...I'd be riding it all of the time.
There are sections of trail that I currently rely on momentum to get me through b/c I can't pedal through it as well as I'd like...or as well as I would with a dually.
Time to save for a trail bike.
