When building two identical frames with different stiffness targets, the amount and orientation of fibres required to achieve the target stiffness will differ. This can create two frames with the same static weight and balance but with different swingweights.
When viewing a forum category menu on a phone in portrait it's not possible to select a page number. When the phone is turned to landscape the options appear. I.e. You can select the final page of a thread rather than landing on page one. Am I missing a trick somewhere?
There are a few variants on the materials used but essentially it's the same process. Carbon is wrapped around a small bag of PU beads or a rectangular piece of PU foam. The heat in the moulding process causes the PU to expand and push the carbon into shape whilst it cures. If you cut through...
from my understanding, the patent was owned by Jack Frolow and Wilson bought the patent when they realised it could restrict other brands. The patent was about 2000 pages long and hideous to circumnavigate!
As I understand it, babolat are no longer selling or supporting / calibrating the RDC machines currently in use by retailers and there are few alternatives for measuring racket stiffness accurately. I wouldn't want to confidently assume a 20 year old machine in California will measure exactly...
Nothing shady or suspicious. The retailer was previously part of our distributer network but we no longer support this system as it was not possible to control the accuracy of how the frames were assembled.
Just to clarify, The Angell frame you demoed was not built or supplied by Angell directly. The retailer you received the frame from has not been authorised by Angell for many years, partly due to the lack of control over build
