Was a lot of work but I got the results I wanted when off-the-shelf failed to provide it. I didn't do a before and after weight but I tried to keep metal removal to the bare minimum.
Here's a -17 one on an alu frame but you'll get the idea of how slim it is... https://farm6.staticflickr.com/5613/...96df9e1c_c.jpg |

Yup, also note that in addition to the small and stretched frame Cancellara used a long stem and traditional deep, round handlebars without a flat transition from the bars to the top of the levers. A classic setup which I also prefer in the configuration of my own bikes...

With my headset design, you can pick any stem you like (length, angle, finish) and easily swap it out for something else should the need arise. And if the design is successful enough, what do you think the next item I plan on making is?
Now that I look again, I should have noticed something was up; you've got a threadless headset on the original fork, and IIRC you said you're running an adapter rather than having replaced the steerer... What gives? Also, nice job polishing the Kalloy Uno, but I tried one of those... flexy as hell, needs about 20g more metal. I had one for the same reason as you; wanted 17°. Swapped it for a Zipp. |

Unfortunately not. They're 26.0mm. They did the F109 for 31.8mm but those were only made with a 6° angle

Ok, that explains why I never found a better option than the Kalloy Uno for my purposes. I'll see what I can do about blending these stems into the ideal pairing for my headset...Stay tuned ;)

Indeed, just like a slim stem slim handlebars look better with a classic steel frame (and 26.0mm bars are not noticeably more flexy)
|
A 26mm bar that weighs the same as a 31.8mm bar is most definitely more flexible, and IME they're noticeably more flexible unless they're steel or boat anchor thick-walled.
What's more, most 26mm bar/stem combos are flat out hanging onto each other landing off a gutter with your hands on the hoods; it's a totally undercooked spec. With 31.8, you can hammer it like that all day, no problem.

The simple fact is 26 is undercooked. How many times BITD have you seen bars that had rotated in the clamp? Quite a few, I bet. It was a spec born when bars were steel. |

Like I said, boat anchor. A 220g ally bar is plenty stiff in 31.8, but sketchy in 26.
What does BITD mean? |
BITD = back in the day

With a 1980's mid-range steel frame plus steel fork, Shimano 105 parts, Aksium wheels, Kalloy stem and Ritchey bars, I doubt an 80gr weight difference is an issue when picking a new stem and bars ;)
But if it would appease all the Hot R' Not'ers, perhaps I'll just go find some super light bars and polish/paint the center section to match, build some ultralight wheels, and come up with some other goofy things I can do to cut weight off my mid-range 80's steel frame bike build :) |

Hey, don't pick on my stem ;) That Kalloy Uno stem is one of the lighter options out there. And the conversion headset saves a decent chunk of weight over the other options. Vittoria Corsa G+ tires aren't exactly heavy weights either. The wheels are on there until I build something better. Groupset was picked because of the black levers and brake calipers, and this was never intended to be a truly light bike, mostly a budget-friendly modernized classic frame. The handlebars are heavy, no doubt, but realistically I'm saving 50-60 grams using something else, spending a lot more, and I'd be stuck dealing with figuring out how to get a matching finish.

form over weight
A four-arm crank is a good example; most of us appreciate the traditional aesthetic of a five-arm crank, and when Shimano ditched it, many of us found the new look tough to get used to. But the FC-9000 has definitely grown on me; part of my philosophy regarding such things is to actively integrate functional improvements into my ideas of what looks good. I'm not a fan of arbitrary styling; to my mind the form of a component should be completely dictated by functional considerations, with only the surface finish being an exception. As such, I'm a fan of what Shimano is doing with anodising these days, and I hope they take it further... I'm not so keen on the odd little asymmetries and styling lines you see on their cranks though. Here's hoping for a less ugly future ;) |

How long is yours? Mine is 100mm and plenty stiff enough for steep hills and sprinting.
