The light weight of CE28N is now incorporated to the SL model which includes the most recent technical analysis with a new approach. As similar to the SL model of the TE37, the mass around the center cap area has been removed, recreating the center circle.
Mass has been removed where possible while rigidity has been gained by added thickness where required. The answer to the weight loss is 50 grams.
Now to the sprint model: CE28SL, where evolution never stops.
