Hi guys
Is there any differences between the duo speed and 5.2? except the 2 speed gear?
Is the duo speed using the 5.2 new improvemens eg the frame?
Different regional Strida distributors sell Stridas of different specs. For instance, the 5.2 carried by Strida Europe has plastic freewheel while the Strida France’s 5.2 is equipped with alloy freewheel. Therefore, no one on this forum can adequately answer your question with certainty. You need to contact your region distributor with spec questions.
