I have sold quite a few of my open mold frames.  they actually sell reasonably well in my area.  i am able to get 60-75% of the price i paid.  people are getting more curious about the value proposition that open mold frames provide.  i like to split up the frame and group set when i sell though.  i find that people either want a name brand group set for what ever they are doing or they want an open mold frame to build their own thing.   

Nice looking Ostro replica there. Anyway, can you show what type of compression plug given by seller?
Because I've experienced it before, D-shaped steer tube is not working well with normal round compression plug. It tends to loose during ride and for me it's so dangerous.

• Headset size: 1-1/2"* 1-1/2”ACR (two 40 x 52 x 7mm: 45x45 deg bearings)
• Rotor size: 160/180 mm
• The rear brake cable exit was changed to the same design as CFR707
• The front derailleur cable routing was changed to the same design as FM1056
• Seat tube was changed to normal seat tube clamp design, same as CFR696
• Removed rack and fender mounts. Only keep two sets of water bottle cage mounts. (My frame has 3 with the downtube mount)
• Max tire size:700x42c  / 650B*47c
• Max chainring: 50-34T / 42T
• T47 bottom bracket
• All mounts removed from fork. There are internal and external routing versions.

• Rear caliper: flat mounts on the chain stay are 25mm thick, so if you're using Shimano calipers & SM-MA-R160D/D adapter, you will need 38mm long bolts (Shimano part Y8N208020)
• Headset bearings: Don't quite trust the quality of the supplied bearings, and considering what a PITA it will be to replace the them, I plan to order new Cane Creek or Enduro bearings for the build
• Front derailleur: cable uses housing from the shifter to to a plastic guide below the BB (pic attached). From there it's inner cable to the RD. You'll need around 1.4m of housing
• Rear derailleur: cable use housing from the shifter all the way back to the rear derailleur. I'm using a GRX810 RD, so I need to use the flexible Shimano OT-RS900 housing where the cable exits the frame to the RD. I'm using a Jagwire Double-Ended Housing Connector CHA062 to join the two cables. Note the Jagwire Pro cable kits (e.g. PCK500 ) also include the flexible cable section and double-ended connector.
• Get some Internal Housing Damper foam (6mm ID, 10mm OD) for the rear brake hose and shift cables to stop it rattling in the frame. I have some made by Jagwire (ZSK600), you'll need around 2-3m

Would you mind sharing the links ?
I tried 3 Spexcel ones, but I'm overcooking in them.

The only great winter(when no rain) jacket I did buy were called Runchita, and I'm still using them as from 2019
They are unfortunately not available anymore.
These are not the same, but I didn't try as they don't have the S size:  https://a.aliexpress.com/_Ey8xBmR

I myself have found only a few third-party lightweight options for SPD-SL. Even though Shimano pedals are reliable, Look KEO seems to be a better choice for cost-conscious weight savings.

But, here are the three options I found:

Exustar E-PR18 CKTI (Titanium axle, carbon-reinforced nylon body) - 246g - 126 USD https://www.amazon.com/Exustar-E-PR18CKTI-Road-Clipless-Pedal/dp/B00LOA0BTU

Exustar E-PR18 STTI (Titanium axle, nylon body) - 256g - 100 USD https://www.amazon.com/Exustar-E-PR18STTI-Road-Clipless-Pedal/dp/B00LOA0BYU

Rockbros LP-R21 (Steel axle, nylon body) - 262g - 40 USD https://www.aliexpress.us/item/2251832644654245.html

is it really waterproof? It seems it's hard to have a waterproof/resistant fabric AND breathable, it's found only on more expensive clothes
don't know if the spexcel jackets from kubackjeee are better, would be good to know

I always have issues with that, with these kinds of winter clothing.
I sweat too much, and I need breathable fabrics otherwise I'll be drenched in no time. What I end up doing is layering up, and always leaving some opening on the zipper to try to cool down, but after awhile in the ride I tend to open a lot the zipper to cool down, and when it starts to get cold then I close again
annoying, but it's what works. Always wondered if a more expensive jacket would give me the breathability, but at least here it's just too much money, so I prefer to be annoyed
