Turning myself in for crimes against Bikes.

Or-
PX-10 reaches new lows



A French bike with Italian components
A race bike to be used for commuting
A vintage bike with modern parts
Built with a spreadsheet instead inspiration

What can I say? I am ashamed of this bike.


In all its 16.3 lbs of embarrassment.
I even tried to write an algorithm to decide my tires.


What do you folks think? Total do-over right?

Do over the cable stops. I'm kinda baffled over the weight though, how'd you do that, or are you sure its accurate? I know those vitus frames are pretty light, but still.

Don't climb hard or sprint with that thing!

16.3#?? I'm puzzled with the weight too, specially with what looks to be clincher wheels(?), brifters and the not so weenie components on a big frame (60CM??) . I would think the weight might be closer to 17-18 pounds??
Did you pump some hydrogen or helium into the tires or something??
Oops!......... I see some carbon on those brifters...and those brake calipers look pretty light from the front with the slotted arms.....maybe it is 16.3 pounds then!

I'll be fair that the 16.3 is with a seat that is currently set to arrive on Monday, it is currently 60g heftier, but looks the same as it will next week.
Anyone interested in my spreadsheet? Gram weights of every part because I dont trust a hanging scale. It also includes my cost and source for building.

After winter I will build some low spoke count wheels with sapim CXrays and it will be at 16.0

Amazing, I've never seen an aluminum PX-10, it looks like it could pass of as a 2010 model. I think your cable stops are on upside down though...

Aha!! counting weight weenie points before they are installed is definitely a C&V Forum crime!!
You will now be required to post clear HD photos of your bike as soon as the weenie stash arrives or is built and installed!
Oh, good idea from a previous poster about a carbon fork too!
BTW, it's looking real nice so far. Nice touch with the ergo bars not tilted too far up. Personally, that's what I think mostly ruins the looks of most new bikes today IMO, in addition to the compact "tail dragger" frames.

It's not really a crime if ya ask me... the only real crime is making a bicycle un-rideable

Personally, it doesn't do anything for me (in a fashion/looks sense) but it seems like it'd fun to ride. I grin like a kid anytime I ride a light-weight bike.

I prefer them closer to my hands rather than hiding behind the downtube.
they function the same, the look can be distracting but this modern Campy stuff is just so finicky to tune that I have a few times had to pull a half turn as cable housings settle and other chain noise occurs. Now that its broken in I could switch it around but then I would have to re-tune it.

Really? That has never been my experience with the many Modern Campagnolo equipped bikes that I've built. What did you have problems with?

Yeah, if the bars need to be tilted up too much then you need a taller stem or shorter reach.
I honestly think many think the "ergo" part of the bar is right at the tip of the barend, instead of the nice flat right under the levers.

Looking good.
What wheels? I see no stickers (nice), how light are they?
Wow on the weight. I have 20# bikes right now. Ironman with Ultegra. Would love to get it to 17# range.

It may have been because I routed both cables to the front (which it is equipped for) giving the shifter cable a harsher bend when exiting the lever body.
Twice I had to tighten the rear DR when i notices some chatter from the cogs and once I shifted the front too hard and pulled the DR down the ST by an 1/8", I gave the barrel a twist and rode to a safe place to fix it.
The ergolevers are brand new, Campy cables and housings. Both DRs are lightly used, but it shouldnt matter on that end. ...Unless a pivot is loose... BRB!

I've only had one issue, but it was my own doing. I put a 130mm rear wheel with 8 speed record ergo onto an old C'Dale frame with 126mm rear end. The RD hanger angle was off by a smidge and the initial setup was a bit of a pain - bottom 4 gears would dial in, but would be off in the upper 4 and vice versa. Fixed that by replacing the frame with a Tommasini Tecno (no more issues) followed by 10 speed record. 8)

That...that's absolutely beautiful. I wish my Campy-equipped bike looked that classy. Well, it does, but that frame look AWESOME.

Furthermore, a frame that large weighing in at only 2.9pounds? Holy crap...

We share the same sense of aesthetic balance (which naturally eminates from a properly set up bicycle IMO).

I own a tail dragger and am planning to replace the frame one day. I don't mind sloping TT's on mountain bikes, but really do not like them on road bikes. I'm a tall guy and have a hard enough time finding a frame that fits me properly. My commuter is the largest frame available in that model, has a sloping TT and I have a frigging mile of seatpost on it.

Nice list but I see no grease or oil on it. Also, are those weights spec'd or functionally individually weighed. Plus screws and washers vary so you would have had to weigh each of those items. Plus the as installed weights of cables and housings vary based on trim points. And was the bar wrap installed and cut and then calculated based upon trimmings subtracted from pre-installed gross weight. Then there is the finish tape on the bar wrap.

Apart from that I'm fine with the build except for that seat post. But what do I know, I don't really care about weights.

Well nothing is mentioned on how it rides, and I'm guessing if pushed hard then not very well. If I remember those frames correctly.
