Inspiration
After crashing a CF frame, I wanted something corrosion resistant and able to take more abuse.

I used some of these frames for ideas:

https://masoncycles.cc/products/bokehti-frameset

Keep in mind I have no idea what I'm doing, but you may see some ideas you like.

Design stuff:
- The cable entries into the frame look amazing. I specified just "hole cutout" and was expecting them to simply route a hole, but they included adapter plates and everything.
- Seatstays: you can drop only so much until they will interfere with the rear flat mount disc. At that point they have to bend the seatstay to clear.
- Seatpost dia: "seat post is 31.6,then you need to choice our 34.9 seat tube ,if you use 27.2 seat post then need to use 31.8 seat tube"
- Dubble butted: no don't even ask. A lot of the options in their quote PDF aren't even available or are incorrect, so just specify them in the email instead.
- Brushed or sandblast: It looks like they sandblast regardless, then hand sand the frame? Brushed is better for anodizing, sandblast gives a more even look.
- Weight: 1.95kg with thru-axle. Quite heavy, probably would be lighter if I didn't use such wide tubes

Timeline:
Waltly as with probably all other bike component manufacturers are likely slammed for orders. Email Sumi with your requirements, be patient. The design stage only took ~17 days (Nov 1) this will depend on how much back and forth there is. Then production was about two months on top of that. I chose "cheap" shipping, another 1.5 month or so to Canada.

Process for etched logos:
- You need to use an old version of CorelDraw (eg X5) to be able to export a compatible EPS file for them. Inkscape won't work.
- To create: Export as EPS, save in version 2 format.
- Text cannot be too thin or it will be hard to etch (like 1mm), even after thickening some text on mine it turned out not great. The big bold logos are fine though.
- I didn't specify size, I think they will just resize it appropriately to fit in that spot.

Future plan:
- Wash all the sand out.
- Anodize part or all of the frame. I did some test anodizing and could only get a few "good" colors: purple, dark blue, brown. Maybe with technique or more chemicals you can do better.
- Run internal electrical wiring for lights.

Not a ton of details in the video, but basically, gave the bar to his friend and it broke shortly after.

Design wise it doesn't look great to have the cable exit right up close to the area of greatest force. If you look at the EC90, cable exits in a similar place, but further back on the bar:

But, other manufacturers do have cable exiting in the middle, so I'm sure main problem was somewhere else.
