Rubber Boot for BB Access Port (S206500002)

Hi spth7ch & Hugo...you are probably not getting answers from the AliExpress sellers because the Chinese New Year holiday which officially started on 2/12/21 essentially closes down all factory production for the month of February.  Factory production ceases a week before that official date.  Although March 1st is just around the corner...the factories face many more challenges than I think...we on the forum realize.  I will post a link to this article explaining the challenges and they are eye opening to say the least.  Apparently, many trained workers do not return to their factory jobs after the holiday...leaving the factory to hire and re-train replacements.  Which would tell me that quality control may suffer on CF frames being produced during the month of March (and maybe beyond?)...this is not fact for any of the sellers we are discussing...just my own cautious belief based on what I am reading...you can decide for yourselves.

Here is the link to the article with a couple excerpts below:
https://www.chinaimportal.com/blog/chinese-new-year-impacts-import-business/

"While the official holiday is only lasting for roughly 5 working days, plus two weekends, most workers remain in their home provinces for an extra week or two. This explains why most suppliers are not back in business until two, sometimes even three, weeks after the Chinese New Years’ Eve.  You will have a hard time getting in contact with any company representatives, including the salespeople, on CNY eve and the following days."

"Finding, and training, a new batch of workers provides new challenges of its own. Skilled workers are, to a certain degree, replaced by rookies. This is one, of two reasons, why the risk of quality issues is at its peak right after the end of the Chinese New Year. Every trade takes its own time to master."

I was lucky enough to get my order in with AWST Cycling Tatics thru AliExpress back in Jan before everything started to shut down.  My frame has arrived in the U.S. (one week ago) as per the USPS tracking...but has not been delivered yet. I am assuming it is being held for customs inspections.  Interesting enough...when Hugo mentioned that "AWST no longer has the frame"...I went and checked.  Their store on AliExpress has no frames, wheels or any product available at all.  Does this mean they went out of business?...or are they just pulling the products because they know there will be nobody available during the holidays to answer buyer questions or process orders.  We have yet to see and I will let all of you know if I ever get the frame or not.

Let me close with my AirWolf experience.  Before I ordered thru AWST...I started asking AirWolf (who is also "YaoFlying") about the stumpy clone.  Asked if they had a medium in stock and could they ship it out by a certain date at the end of January 2021.  They responded they could meet those requirements and I just needed to place my order and pay for the frame.  I waited 1 day and just asked a follow up question regarding the timing of shipping it out before the CNY and the response I received was "we don't have Medium frames...only Large...we will not be producing them until next month.  If you place your order now...you will be first to get one once Medium's are finished"  I said to myself "next month" would be February...won't everything be closed down for the holiday?  Then a day after we had this conversation...they raised the price of the frame from $780 to $856...so I backed away from AirWolf.  Take that for what you will...I was a little dubious about their business practices.  I know others have purchased frames from them (they have a presence on EBAY, Amazon and AliExpress) and have been happy with them.

Some tips about treating the rivet nut prior to install and using epoxy adhesive as an insulating layer to prevent galvanic corrosion between the aluminum and carbon.

Thanks Thrill!...Airwolf is telling me the 2193 grams is just for the frame, rear derailleur and seat post clamp.  My max cutoff weight for this project is 2280grams...so approx. 5lbs...I am shooting for a 24"ish" lbs (24.25-24.80 lbs) finished build weight.  Looks like the Stumpy clone is right near the max...but within my spec.  Thanks again for your help!
