The Thudbuster ST features all the attributes of the LT in a smaller version. The Thudbuster ST has a shorter parallelogram mechanism, which is particularly beneficial for enthusiastic marathon riders, as well as XC bikers. The question of whether a full-suspension bike is truly necessary for cross-country trails will never be definitively answered. The fact is that a sensitive and responsive suspension seat post with good functionality has the same effect. After all, the rider - and not the bike - is the heaviest component in the entire system, and the Thudbuster ST provides excellent suspension for this component. This ensures that power delivery remains intact even in tricky situations. The Thudbuster is easy to install.
