I am selling my 2013 18" Kona Big Kahuna 29er hardtail mountain bike after replacing it at the beginning of last year. It was ridden during the 2013-2015 summer seasons locally, late April through August each year. The bike was meticulously maintained, my boyfriend is a bicycle mechanic. Component upgrades include a lighter wheel set (Stans Crest ZTR tubeless ready), new front chain ring and chain as of late 2015, and a rebuilt shock in mid-2015 (routine maintenance). This bike is lightweight and great for cross country racing or long trail rides. No cracks or dents in the frame, but normal riding wear is evident. NOTE: The brakes will not be the Guide RS that are pictured here; the original Avid Elixir 5 are on the bike instead.
