De beste oplossing voor Trek

Heb je een Trek fiets die geschikt is voor Duotrap dan is dit de perfecte oplossing. Geen losse elementen meer aan je fiets maar mooi weggewerkt in je frame. Meer zowel snelheid als cadans. Installatie was zelfs voor mij een fluitje van een cent. Ik gebruik hem icm de ELEMNT bolt.


  • Mooi design
  • Eenvoudige installatie
