The XP was the most fun sled ever made - but I liked my XR more. The 850 takes it to a whole different level. But darn, the 900T is Bad to The Bone!

The xs 821 will pull rpm’s down on some sleds doesn’t seem to be all. Some have suggested sleds on the longer C to C side are more likely to lose rpm because the 821 are a little shorter and load harder than the 571. With gboost and stock clutching you’ll probably have to add weight to the pivot bolt to keep rpms where you want them. I don’t know how much because I ran HRSS ramps all year, but a gram or 2 would probably be close. I should add the gboost seems to take a bit longer to break in I wouldn’t make any adjustments till you have a 100 miles on the belt
2-3g on the pivot for a gboost. You are correct, an 821 is short, if you have a proper Z measurement the 821 loads really hard, they are 44", gboost are 44.25 and 571 are getting close to 44.5"
