Headset loose three times
Over the last year, the headset on Trek Emonda sl6 is loose. Bearing are all ok and in since new. After opening it this time, and cleaning out the upper bearing space, the bearing appears to fit in a lot more loose than other bikes. It has a od of 41.0mm and the diameter in the upper frame is 41.3mm. It may look like that after cycling for a while, the bearing might be rocking and pushing up the stem which in turn causes the loose headset. ...bearings are ok, insert in the steering tube looks ok, stem is torque correctly, there is also the correct amount of shim washers about the collet on the upper bearing and below the top cap. The main question is the Trek tolerance ok with 41.3mm ?
