I got one of these last year, so solid for the price.
Things that ive upgraded that made it so much better:
Grips, oury red
xt chain and rear deralieuer
Next thing to go is the dart 3
Did you upgrade anything?
Only thing I have done was the XTR front derailleur, and a Lizard skin chain stay protector I had laying around from my Cannondale Gemini I has that got swipeda year or so ago, I bought the Reken as a replacement bike because it was in my price range, and it was quite a change going from a 40 LB all mountain rig, to the Reken. This thing flies, such a light bike. My wish list of upgrades are:
XTR rear derailleur (Probably should do chain too)
Oury grips (had them on my Gemini and loved them)
Front fork, though I have yet to decide on what fork.
Slowly building my soon to be wife a Reken, Right now has some take off cranks stem bar and derailleur, manitou minute fork easton seat post. I just test fit the wheels off my trek crossrip 700Cx32 and the fit perfectly. thinking that is the direction that I am going to go with it for her. a set of 29er wheels and aggressive cross tires.
