I use Noodles on 3 bikes with 3 different stems. The flex characteristics out on the hoods is different for all three. The Tech DLX 11cm extension feels the flexiest. It feels a lot less flexy now that I have it about 3/4" below min insertion. The Nitto Pearl 11 is less flexy still, which I attribute to the still shorter quill. Least flexy of the three is the Nitto lugged, which is also the shortest extension of the three, a mere 9cm. None of the three would I call objectionably stiff, nor would I call any of the three objectionably flexy. I have zero concerns about the strength of any of the three.
