I am thinking the ST bosses are low so they are always the same distance from the BB. That way bottle bosses can be brazed in before the frame is built. And there's no need to "worry" how long the ST will be. I skimmed through the most recent Taiwan factory bike build photos to see if the bosses are NOT there after frame is fitted together. It looked like to me the bosses were always present, so the bosses were brazed in before frame assembly. https://cdn.shopify.com/s/files/1/1403/7343/files/000077810024_791d774b-0d9e-4b91-8cfb-5be6b97b59e7_1000x.jpg?v=1726785548
