Re: Velobuild VB-R-168 Frame
Frame looks really good! You got it. I shoved the battery and wireless transmitter both in the seatpost without issue. The cockpit is so clean that my junction box sticks out like a sore thumb now. In retrospect I would have spend the extra money for an internal handlebar junction A. Build is 97% complete as I'm just missing a couple of parts but took it for my first 70k ride this am! Felt awesome. Definitely a better fit for me personally. The bars weren't as flexible as I thought although they aren't suuper stiff. I also liked the curved shape of them and wasn't sure about them at first. Climbs well, very responsive. Overall very happy so far. May 14, 2021, 07:03:27 PM |

Re: Velobuild VB-R-168 Frame
Did you use the SM-MA-R160D adapter? https://si.shimano.com/pdfs/si/SI-8NU0A-001-00-ENG.pdf Could stick with a 140 if you wanted to save a few $$$ and a few grams Don't think braking performance will be affected much May 17, 2021, 04:21:36 PM |

Did you use the SM-MA-R160D adapter? https://si.shimano.com/pdfs/si/SI-8NU0A-001-00-ENG.pdf Yes I used an adapter and the 160 rotor. Thought I could use the 160 without an adapter but missunderstood. May 17, 2021, 05:03:23 PM |

Re: Velobuild VB-R-168 Frame
Ultregra and Dura-Ace are squarely in the realm of diminishing gains Marginal performance improvement and weight savings / dollar Typical cheaper weight savings areas would be bars and seatpost, but that's not possible with the 168 (I suppose you could cut some excess seatpost for free...) Tires are a good place to save some weight, especially since they are a consumable part that will need to be replaced anyways. Depending on your current saddle, that is another cheap place to save weight (especially with Chiner parts) If you are including pedal weight, and if you don't mind speedplay, there are light Chinese Speedplay compatible titanium pedals out there. Finally wheels and spokes. But this is where diminishing returns start kicking in, even with Chiner parts June 24, 2021, 08:45:00 AM |

Re: Velobuild VB-R-168 Frame
https://ccache.cc/blogs/newsroom/2020-road-gravel-groupset-weight-comparison Found this online, not sure of its veracity. I'd switch to a Di2 system for the shifting performance, but not just for weight savings. June 24, 2021, 08:52:37 PM |

Re: Velobuild VB-R-168 Frame
i build frame size 58 I have an r12 with 50mm 28/28 at about that weight. 19.2 with pedals. Why are we so heavy? The only upgrades i can think of is a lighter wheelset and get red. Udi2 you save like 50-100 grams. How much difference does a tire set give you? 100 grams? June 24, 2021, 09:22:06 PM |

Re: Velobuild VB-R-168 Frame
Is the seat tube that fragile? You're referring to the bike stand clamp, right? Is it a convention not to? It's a rubber grip. I treat my bikes with care, id assume seat tubes arent meant to be clamped, probably not what the manuf made it for. Rubber definitely probably helps but still, ill always use a seatpost. Udi2 vs force shaves 100 grams tops. Honestly, if you go with 50mm feder series vs 50mm classics, thats 200 grams saved there. Almost half a lb. a lighter tyre set would save 50-100 probably. Speedplay lookalikes save 100-150 i think. Problem is you cant get a lightweight AND aero bike, aero bikes from china are always over 1 kg. Thats all the weight savings i can think of, im assuming you use a cf saddle already. So if you go with the same depth and swap everything, youre looking at maybe 1-1.5 lb MAX after swapping anything and im so fat that that weight doesnt matter, i just hate seeing my bike on the scale.

Re: various questions about custom build vs brand road bike (cost, issues, warranty)
This is what I had. https://wheelsmfg.com/bb86-92-outboard-abec-3-bb-for-24mm-shimano-cranks-black.html I think a fresh reinstall would have taken care of the creaking. That's what I did when I switched to these. https://wheelsmfg.com/bb86-to-29mm-dub-compatible-kit-for-pressfit-86-92-bottom-bracket-with-flanged-dual-row-black-oxide-sealed-bearings.html Haven't had any new creaking since I installed these back at the beginning of March. A good cleaning, new coat of grease, took my time. Hope that helps. July 02, 2021, 01:06:30 AM |

Re: Velobuild VB-R-168 Frame
Did my first 50km ride today! Love it!! Build went pretty smooth, only real pain was setting up the rear caliper without disc rubbing, but I managed to get it right in the end. Will post some more details later.
