The Del Sol Tradewind HD (heavy duty) cruiser was developed to be ridden and enjoyed in a multitude of environmental conditions. Built around a 6061 aluminum frame, our HD model is spec'd with aluminum rims and stainless steel spokes for added strength and rust resistance. And, with its sealed-bearing alloy crankset, KMC Rust-Buster chain and heavy-duty built in kickstand, the entire bike is virtually element-proof. Best of all, by using alloy and aluminum (as compared to hi-tensile steel) for many of the components, not only does it inhibit rust, it keeps the overall weight down. So, whether you are cruising to your local park, pedaling down the boardwalk, or you have a bike rental company, rest assured that we built the Heavy Duty straight into the 2020 Tradewind HD to provide years of dependable service!
