So I was thinking about upgrading to a longer track sled. With most manufacturers going to 129 as the standard size and some offer a 137 for trail sleds it has me wondering. How much snow can a 137 x 1.25 lug handle? Around here we get a rare blizzard which will drop 2 feet. I found out last year how easy it was to get stuck with a 121 x 1 inch lug. I realize there are other benefits when it comes to the longer track as the suspension will not beat you up as much on the smaller bumps. Seems like there is almost no reason to not get a 137 unless you don't have the space or ride really tight trails.
