The Chinese carbon clincher tri-spoke?
Does look borderline tbh.Easiest way to measure is to take a photo with the axle at the centre of the photo and with a plain background. Then use photoshop to cut out the wheel circumference and up the contrast, then count the black vs background colour pixels.

I'm trying to sell the wheel below, but someone on the UK TT Facebook group is saying it's not CTT legal as the holes are not more than 45% of the surface area.
Are they right? How would I find out? What measurements would you need to find out for me?
