SUMMUM R
Mondraker
Downhill
SUMMUM R è una MTB downhill (2023) by Mondraker, parte della famiglia Summum. Questa bici è pensata per chi cerca un setup off-road bilanciato. Assetto: equilibrata. Uso: più a suo agio in bike park (gravity). Punti forti secondo le metriche: sospensioni capaci su terreno sconnesso e un feeling più confortevole sulle lunghe. Il lato meno forte è meno focus sulla velocità pura rispetto ai setup più race. Prossimo passo: confronta questa bici su MatchBikes.com.
