First sub5 Orbea Orca '24 - 4,835kg

[Greeners]

As has been said before, this is a stunning build-up on a lovely frame.
Great attention to detail & execution. The final pics make me wish I could throw a leg over this fine bicycle.

Try looking at the Ti-Parts Titanium catalogue. They have a variety of screws and bolts. Also ready-made kits for the various groups

-extralite hypercap for headset
-ashima for rotors

-custom levers nuts

You mention hypercap for the top cap but it looks like you have a carbon top cap with hyper bolt. What is the concave top cap you’re using?

BTW, I live the shots with all your parts laid out. Very impressive and a great spread.

[aeroskii]

thoughts on the extralite hoses?

[wheelbuilder]

Absolutely fabulous details. Chapeau

how come your seatpost is so light? did you cut it

That's not cut... if anything it's heavier by 3g from what Darimo quote in 27.2mm, 250mm long;

I've made a spreadsheet detailing the weight differences from a stock orbea to this build, mainly because I'd like to see which parts saved a lot of weight (spoiler: it's all of them). It looks like a sore with certain system weights having to have it's own column; I couldn't source info for smaller parts of the stock build. If anyone could make the spreadsheet tidier, it would be greatly appreciated.

Thank you, that is a very interesting and deep insight into what you did. Good basis to pick and choose for my own optimizations. May I make a copy of the sheet?

Stunning indeed! Thank you for sharing the process.
