We have found when studding the track on the 120s that you add a lot of rolling resistance to the drive train which will slow down the sleds take off and also reduce the top speed, so to solve this problem we recommend Ice Screws. They screw directly into the lug of your track. They have many advantages over studs. They cost less, they're easy to install, they have far less rolling resistance than studs, and they also make your track have a deeper lug. So why not use them? (Come in boxes of 250)
