protein
Mitotic spindles are made up of microtubules. Microtubules are hollow cylinders that have a diameter of about 25nm
Spindle Fibers
The spindle fibers themselves are composed from microtubules. It is interesting to note that 'motive enzymes' - little enzyme motors - do the actual hauling/moving of the chromosomes along the microtubules from a to b. See MTOC : micro-tubule organizing center.
Microtubules consists of hollow tubes which provide support of the cell.

Thin hollow cylinders made of protein that provide structural support for eukaryotic cells are microtubules. Microtubules are involved in nuceic and cell division, organization of intracellular structure, and intracellular transport, as well as ciliary and flagellar motility.
microtubules.... might be right
The description of microtubules is hollow rods or hollow cylindrical structures. They mainly help to shape and support the cell.
