I now have ~500 miles on the bike and it continues to perform well. I have upgraded to 25mm tires for my general commuting and have no issues with frame clearance. One thing I have come to respect on this bike is the wheels. They continue to spin true, despite hitting some fairly rough pavement on my commute, and I am impressed with the hubs. They spin forever.
I also have found that the seat post has a tendency to slip down over time, even at recommended torque...but a little Fiber Grip compound seems to have solved that.
After my second ride, the bike seems to perform quite well. I spent quite a bit of time on dailing in the brakes, shifters, etc. and i found the bike to have a comfortable ride that provided a good platform for a consistent pace.
I am attaching a photo of the bike, for a more realistic image, along with a map of the second ride that shows hitting a top speed of almost 27 mph along a fairly flat road.
Apparently, I get to be the first to write a review! ...lets start from assuming you have the same questions I did after finding this bike...carbon frame, Shimano 105 11-speed, internal cable routing, etc... at the seemingly rediculous price ($830 at the time I ordered).
Most importantly, ignore the description on Amazon...the color is NOT red as it states in the details, and the tires are not Victoria...
Let me start by saying that I have long been a fan of PZ Racing components. The components that I have purchased have always brought satisfaction in the price vs performance category. Everything from the seatpost on my Fuji to the stem on my Blue, I often get compliments on the parts, and I have always been satisfied. This is the main reason why I even considered purchasing a full bike with such little documentation available...
The main points you need to know, is that this is a well spec'd package on the cheap. They did not compromise on the Shimano 105 group. Brakes, shifters, cranks, BB, chain rings...all Shimano. Everything else is house branded PZ Racing with the exception of the San Marco Era Dynamic open saddle, and the Continental Grandsport Race road tires (23c).
The bike looks grey in the photo, but is actually closer to black...which I actually like better.
That is the good news. Now for the bad...
Bike Assembly: I can only say that this typifies why people cringe when they read "Made in Taiwan". First off, the chain was not even threaded through rear deraileur. They just kind of wrapped it around the the bottom of the deraileur instead of threading it through and around the jockey wheel. This was the most obvious thing i saw after doing a rough unpacking and setup. I had to break the chain and thread it properly.
The other thing I am not thrilled about is the wrapping of the bar tape. The brake/shifter cables are actually taped to the top of the bar and run behind and down the back side of the bar. It is odd, I have never seen that strategy before. I suppose it does create a clean look on the front of the bike, but I have yet to ride it and see if the cables under my hands will bug me.
Another concern I have is that, there is no information I can find on some of the components used for this bike...like the wheels (DR8.1's)... I can not find any info on the web about them and so i do not know if they are actually a standard product of PZ Racing...but they are setup true and are light weight.
I previously requested a Geometry chart of the frame, and that question went unanswerd, but I found a geometry chart of the frame that I THINK they are using, after researching on my own, on another site:
*Crank Center to top of seat tube: 55cm
*Effective Top tube Length: 54cm
*seat Tube angle: 73.5
*Head Tube angle: 72.5
*Assembled standover Height: 31" at front sloping to 30" near seat
More geometry specs you may want to know is that the stem is 100mm (+/- 5deg), and the cranks are 172.5mm
All in all I am happy with the value and coolness factor of the bike (though I have not actually been on a long ride with it yet, and will post an update after I do). It seems to be a very well spec'd package with some respectable components, and there was no compromise in the groupset. Despite the fact that I am impressed with the components, I would not feel comfortable reccomending this bike to someone without basic bike mechanic skills to handle possible assembly shortcomings...unless you plan to bring it to your Local Bike shop to assemble and check it out for you. My rating on first impression i considering the price I purchased it for.
