Another feature that differentiates the two models is the fact that the Voyageur IG3 has an internal gear hub, rather than a derailleur design. The internal gear hub system tends to offer a more dependable performance than the derailleur system. The double wall rims of the Voyageur IG3, which offer increased support, are the third feature that puts the Voyageur IG3 above the Voyageur 21. However, if having more speeds is a priority for you, the Voyageur 21 has twenty-one.
