Does anyone know, what exact axles dimension is used in WCB-R-306 frame? Instead of ordering original axles I want to buy a lighter version

Any updates about WCB-R-369 production state? Do they have any plans to sell it to the customers in near future?

I'm riding WCB-R-093 frame from 2017. Frame has good quality, but it is too light (little bit flexy rear end even with my 125 lbs, frame size 48). I rode probably 30k on the road and about 10-15k on my trainer. I had couple of crashes, including nasty one, broke handlebar and seatpost, but frame is OK. Good communications with Workswell, but initially it took them about 2 months longer to produce my frame.

Also right now I'm looking for thir WCB-R-316 frame for newer build. They quoted me with this numbers:

- Normal weight Frame size 54cm around 1100±40g
- Normal weight Fork weight around 460±10g
- Super weight Frame size 54cm around 860±40g
- Super  weight Fork weight around 400±10g

- WCB-R-306 Full internal cable routing Normal weight Frame =769USD(Include:frame, fork, seatpost,clamp. Finish: black matte/glossy)
- WCB-R-316 Full internal cable routing Super Light weight Frame =879USD(Include:frame, fork, seatpost,clamp. Finish: black matte/glossy)

- WXY Shipping costs to EU include the VAT taxes =247USD
