The Caliper Spoke Woolie is very similar to the original Wheel Woolie, except it has an angled head. Like the Wheel Woolie, the head is constructed of polypropylene fibers that reduce splatter.

The Caliper Spoke Woolie is a great product for gaining access to the back of your wheel's spokes, in addition to a variety of other similar places that you might sometimes have a problem reaching.
