Level S4

STS Difficulty S4 by http://singletrail-skala.deAn S4 trail is a very steep trail blocked by huge rocks and or challenging sections of roots alternated with loose debris. Extreme steep ramps, narrow turns and steps where your chain ring will inevitably touch ground are returning elements of it (and the fun you will have while riding it, too.)
