YAMAHA "DOOLY" RUNNER/EA 4"
The Dooly??? has two Flat-top?? runners mounted on a plate for each ski. The four contact lines on the snow surface will help decrease darting of your sled as it makes its own groove in the trail. When in a turn, only one of the Dooly??? bars will be in contact with the snow or ice. Therefore; a Dooly??? with 6" of carbide on both runners will have the same turning power as a single runner with 6" of turning carbide.
