Thanks to Minkair, thanks to Amuro for the “magnifying glass” 
Has anybody noticed the aluminium holding part for the bottom bracket of the new MAS is much different to the older version?
The older version is made of three parts, a tube for the bottom bracket and two “carrier”, which connect the bottom bracket housing to the frame tube. The connection occurs via four welding seams, two of them from bottom bracket to the “carrier” and two seams connect the arms to the frame tube (visible far better on Amuro’s reply below).
The new versions seems to be one part, the distance of the two “carrier” together is much smaller, additionally there is an (amplifying?) base between the “carrier”. The position and shape of the welding seam has changed, now it looks like there is only one seam.
I would like to know why this part has been changed, for design reasons only?
Hard to believe…
