This is the first Summum of the entire range, and it's a bike that results from more than 20 years of experience in building high performance DH bikes. And this is not nothing, with several podiums in the World Cup and World Championship 2016 in Val di Sole, monopolizing the entire podium of that year.
A historic moment that proves that even the most basic of the range can reach the highest level.
It is not for nothing that the suspension system and the main features are identical to those of the Summum Carbon RR with which our riders of the MS Mondraker Team compete. The geometry kit is optional.
