Napínáky patří jak k biketrialovým resp. cyklotrialovým rámům s horizontálními patkami, tak s těmi vertikálními. Správné napnutí řetězu a usazení zadního kole je velice důležité nejenom pro rychlý přenos síly z pedálů, ale také pro jeho opotřebení. Nesprávné napnutí či usazení zadního kola může mít za následek i kroucení zadní stavby a tedy rychlejší odpis rámu do věčných lovišť. Vybírejte tedy pečlivě a použití napínáků se určitě nebraňte!
