I have two Trek Rail cruisers, I consider these high performance cruisers, unlike the vintage steel bikes, they have aluminum frames, rims, hubs, etc. they came standard with Bontrager tires capable of handling a whopping 75 psi pressure! Properly setting your saddle height and handlebars for ergonomic efficiency definitely narrows the gap between “beach cruisers” and other performance bikes. Anybody have an opinion or input on this?
