Name for a part on stands/trainers So I am building my own trainer/stand for my bike but I am hung up on one part. What is the official term for the part that attaches to the hex bolt on the rear wheel?
In the manuals/parts lists I have seen, Schwinn and Blackburn refer to the part that envelopes the ends of the axle or quick-release skewer as a "cone". Minoura refers to it as a "grommet" at the end of a "coupling".

I don't have a Cyclops manual handy. I also don't think there is an industry standard name for this part, as there is some variation between all manufacturers when it comes to the coupling/mounting mechanism of their trainers.
