I'm going to open up a can of worms:
In January of 2011, I was contacted by Guru about becoming a Guru dealer. They only required one frame to become a dealer so I decided "why not? "A the time, KWalker was bashing his second-hand Photon here on ww so I requested that they respond to his claims; I thought Guru performed an adequate job of defending themselves.
I also stipulated that my "demo" frame would be under "x" weight as specified by Guru's management team during a conference call. After a couple of months, I received my frame. Immediately, I stripped and weighed my Photon: heavier than promised.
I told my rep that this was unacceptable as I had stock Parlees that undercut the Guru's weight. Guru responded appropriately and let me keep the frame while a replacement was built.
Too much time passed while I was waited for the new frame. One day, while waiting for the replacement, a customer told me that another LBS owner had recently ordered a Photon. I didn't want to carry a niche brand that a competitor was carrying and blatantly told my rep that it was me or them; no in between. I was assured that all was well. If memory serves, it took 3.5 months for the replacement frame to arrive. I stripped and weighed it and this time Photon 2.0 met the weight requirement. I built up the bike and put about 1000 miles on it. The paint was not pretty. I'd label it as sloppy and I'm sure it was heavy (stock paint scheme). Paint dripped into the cable stops requiring some reaming to run cables and the excess made running full length Nokon cables impossible without the over-spray digging into the the housing. The seat-post diameter was also out of tolerance and required over-torquing of the seat-post collar and CF paste.
I enjoyed riding the bike (video of me descending Hog-Pen in Dahlonega GA: http://www.youtube.com/watch?v=I6T1QMDexH4
" onclick="window.open(this.href);return false;" onclick="window.open(this.href);return false;" onclick="window.open(this.href);return false;) but I did the geometry to my spec. I thought the bike rode well and liked it.
Shortly thereafter, I attended a training crit and was chatting up a local doctor. He told me he was buying a Photon from my competitor after I was told I would be the town dealer. I spoke with my rep and reiterated my stance. I ended up sending the overweight and underweight Photons back to Guru and chose not to be a dealer.
So in conclusion:
The Photon is a nice bike; I don't have anything bad to say about it.
The paint is marginal.
The wait times for my frames were too long.
I didn't approve of Guru's business practices.
Guru's QC is questionable.
