Thanks a bunch for this post - I had exactly this frame and colour (even size!) sitting in my AliExpress cart and I've just gone ahead with the order thanks to this info.
I'd be keen to hear how you get on with other tyre sizes - I've got some 700x48 Tufo Thunderos ready to go in mine. Looks like from the earlier posts though there's at least room for a 50mm in the rear, so I assume the fork is similar.
Sweet! I think 48 is about the max I would comfortably run in this frame for 700c, though 50 would fit with not a ton of room for tire knobs or mud or anything. The fork is not a problem, there's lots of room.
Chainstay width measurements:
- 311 mm from rear axle (i.e. edge of 700c rim, roughly the fattest part of a 650b tire) = 60mm
- ~325 mm (i.e. fattest part of the 30 mm tire I have right now) = 59 mm
- ~330 mm (i.e. roughly at the fattest part of a large 700c tire) = 57ish mm
Would a pair of race kings fit this frame?
Probably not, see chainstay width measurements above.
Also, i can't find a proper BB if i want to use sram dub? They don't have T47 with 86,5mm?
I'm using the SRAM T47 BB and even though it's nominally for 85.5 shells, I can confirm it works perfectly fine in the 86.5 mm hubshell of this frame. With RED cranks, the fit is absolutely perfect with a 2.5mm driveside spacer and the preload adjuster turned all the way out. My subcompact chainrings sit a little closer to the frame than stock chainrings would, so with a 2 mm driveside spacer you could get some preload adjustment.
--------------------------------
I'm nearly done building up the frame, I only have routing through the handlebars + brake bleeding left to do. It's taken me a lot longer than I anticipated, not because of the frame, which has been really clean and easy to work with, but because using a dropper post with Di2 is a foolish choice and the build process sucks (Shimano is seriously so far behind SRAM in this space that it's depressing). Doesn't help I've messed up a few steps and had to backtrack. The only notable frame modification I've had to do since my last post is to scrape off the paint around the lip of the bottom bracket - trying to install the BB without doing this shears off a whole bunch of clear coat/paint and it's not great. 10 mins of scraping with a utility knife completely solves the issue, and the BB edges are nicely flat and the BB sits completely flush.
I should be able to get a little ride in tomorrow - will see how it handles in the 50 mm fork offset position, I'm aiming for quicker handling currently.
