How long did it take to deliver to you? Mine parcel look stuck in Germany for at least week, and didn't moved at all... I thought that producing frameset and then sending it to EU will be a problem ... Not delivering parcel from Germany to Poland 
My order took a long time in general, because there were some issues with the fork, but Jack was nice about it. It arrived in Germany (DPD-DE, Flight has arrived status) on the 7th of April, then "Customs cleared. Awaiting pick up" on the 9th. I had no update since then until Monday (20 April) when I received a text from DPD that they'll try to deliver the package tomorrow (21 April). So between arrival in Germany and delivery to Poland it took 14 days... It was way slower than the wheels, but I guess we are just unlucky.
If 11cm is still okay:

(Also available on AliExpress I believe)
I rotated the bag (front is pointing backwards), so that the screws would fit.
Quality wise, I am pretty happy
Unfortunately, I need something lower than 10cm - I'm planning to do a triathlon with that bike.
