The main reason to wait for 24mm is for people with a BB86 frame, since a 29mm DUB crank (made of aluminium) requires the use of smaller bearings. 24mm needs steel or titanium - aluminium has a risk of shearing at those smaller diameters. Weight is roughly the same or slightly in favour of the aluminium cranks normally. If you have any other type of frame you might as well use the 29mm version.
Chinese PM options are XCadey or Sigeyi, they use the Easton interface.
Best Chinese chainring options are Stone or Pass Quest. Lexon is another option.
The advertised weight is for size 50/M, which is a closer to traditional size S/52
Hello, I am in NL in the Eindhoven area, I may be interested on 1 frame...
What are you going for (which size and design)?
I agree it would look a heck of a lot more satisfying if it was parallel to top tube, however I like an angle to it so when I’ve got race nutrition in the BTA bottle it won’t leak out the bottle as easy.
You should see some of the other shit house things I’ve done after seeing the arms race the pro triathlon peloton has done with bottles. Pic below is the more tame set ups I did.
All parts have finally arrived and got the rig set up. This is what it looks like pretty much in race set up (1st race is IM Lanza so front mech needed, but will be removed for flatter races).
Made a DIY BTA bottle cage plate from an AliEx carbon plate and a 3 slot bottle age adaptor common in MTBing.
The Trek Speedconcept Gen 3 (disc brake) specific downtube bottle doesnt work on this frame as it comes, however I'll find a way to mod the that bottle cage to fit. That or use the Orbea Ordu OMX or Cervelo downtube bottle.

I'm 5'-10" to 5'-11", inner leg length i would say is normal. I've always run size 54 bikes (cervelo, giant, scott), so I'm expecting this to fit similarly. You can use BikeInsights.com to compare frame geometry's. I compared my now old Cervelo R3 to the SL8 (TTX68 is exact same geometry), and found 6mm more reach and 11mm lower stack.

6.94kg - $2900ish all in. Weight is plus or minus 50gwith grease, and misc hardware not accounted for.
I acquired most of these parts used over the course of 4-5 months, via ebay and facebook. I learned about most of the build options, not named shimano, from this site or via youtube (GC Performance, Pat Lino, China Cycling, etc...). I also built this bike by myself, first time ever doing a frame-up build, and used GC's SL8 bike build and his other videos.

I have wheels from Peter on the forum (xmcarbonspeed), with 50mm deep and 33mm wide (that is actually 34 at widest part.
With my gp 5000 s 30mm, they come at around 33mm.
Base price of the wheels was around 450$, with ratchet hub, 1420 spokes and my custom logo. Peter was really helpful. Production and Delivery took about a month
They feel really nice to ride with, and so far got 0 problems.
One note is that freehub is loud, but a bit of grease reduce it to a pleasant level. I can send pics if you need
