You might try using a Plastiband from Baumgartens as a replacement.
They come in 3 sizes--approximately 2", 4"  and 6".  I've never used
one
on a DC100A, but have used them on DC600 and DC2000 carts with some
success.  They're made of polyurethane, just like the original tension
bands, but lack the lubricant.  I find that a bit of dry silicone lube
helps out in that respect.
The technical support guy at Imation told me that the original tension
bands were stamped as rings from a sheet, then twisted and applied with
a special machine.  He tried to find the manual version of the machine
used in the 3M QA lab, but came up empty.
