Good high performance cylinder. Awesome 2" shank but narrows down to about 1-1 1/4" threads for fork mount. The transition was very sharp with a very small radius, creating a high stress concentration factor. If the shaft bends or breaks I would expect that to be the area where that failure could occur as the rest is very reliable. I think that this technical detail should be taken into account. Follow-up report after using this cylinder, the shaft is indeed broken and the shaft diameter has changed as expected, failure. This cylinder should not be purchased with the current stem design.
