35mm would just be slightly lighter. Usually 40-55mm deep wheels have such a small weight penalty over ~30mm that its a no brainer to get the deeper wheels. Crosswind stability for wheels below 55mm deep is not much of a concern. Id don't think 9velo is a good value. I avoid many of these premium Chinese brands that are trying to compete with western brands. Price is double that of an OEM, and the product and support/warranty is the same, sometimes worse.

I'm open for other suggestions. I thought 9velo was OEM? What wheels are you running and why?

Why ? I don't need more length, my stem is already small. I usually run 120/130.

Sorry, my message was meant for @TikO.

I'm 170 with 79 inseam and same saddle height. Went for 49 and have a 100 mm bar. I run the only 2 spacer that are required to run the bar (15mm).

Looking at the picture, you could also swap a seatpost with a offset to accomplish more length.

I got an offer from Carbonda for a CGWO1 based wheelset with DT Swiss 350 or 240 or Novatec D791/792SB hub. I can't find info about the rim and how well Carbonda makes wheelsets. Does anybody have info, or has experience, on them?
I am looking for a 35-45 mm deep wheelset for the Carbonda CFR-505 SL frame.

Great to read about the Carbonda CFR-505 SL. The frame doesn't have it's own topic, I'll post my item here. (moving it from this topic)

I'm new in the world of direct OEM market carbon frames. I'm new in this forum. Until two weeks ago I thought I was going to order a new aluminium gravel racer from a small company. Before that I wanted a Vitus Venon Evo but it is not available as a frameset. Then my interest in Chinese OEM got triggered. 

I'm thinking in buying a CFR-505 SL because I need a gravel racer which is low weight and not a bikepacking gravel bike with many mounting points (like CFR-707). It needs to feel at home in the middle high mountains of France and Germany and the Eifel area. Forest roads. Light weight but occasionally it will be used for 2-3 day trips so strapping a saddle bag, small frame bag and handlebar bag needs to be no problem.

Currently I'm riding a 11kg heavy steel bike (Vitus Substance) and although this bike is great and has seen mountains as high as the Alps, it's time to retire.
See below, my 56 cm sized steel frame (white) compared with both L and M size CFR-505 SL (black). I'm 186 cm, inseam of ~88 cm. Both frames - steel and CFR-505 SL - don't differ much in geometry. Another reason not to choose frames like the CFR-707 or Tantan Seraph GR201.

I don't think I order the CGB-02 integrated stem/handlebar. See below cockpit example (FSA SMR), this for me, is good enough. Is makes maintenance easy. Maybe I go with a Deda Superbox. Not sure. I need a round handlebar.

Now, I filled in the contact form on Carbonda's website but didn't hear from them yet.

Some questions:

• Can you think of a reason why not to go with the size L?
• What do you think, is the 505 suitable for these small adventures or is that 707 specific territory?
• Does somebody have a recent contact/employee at Carbonda where to place an order/ask some questions? 
• There's a place near me where they can paint the bike per my design. This is more expensive than  Carbonda but I want the frame to have a logo and name. Can Carbonda do lettering or vinyl stickers?
• Is the example cockpit possible with the 505?
• The seat stays intersect the seat tube a few centimeters down. My Vitus Substance is "old" triangle. (I don't see that in Bikeinsight compare tool) Does this effect compliance? I'm about 70kg, I can use every bit of compliance since my weight won't effect bending seatposts or rigid triangles, etc.
• I might have some more questions...

Thank you.

How is the ordering process going? What the status of your build/order/thinking process/decision making?
I'm also interested in building an all-road racebike based on the CFR 505 SL.
