Graham called us up and described his new fascination with riding gravel. We concur, it's awesome to get out on the "Strade Bianche" (Italian for "White Road") - less traffic, more challenge!
He advised us that he had recently replaced a broken rear rim with and entire wheelset. The old Italian Bianchi Reparto Corse (Miche) hubs were fine, and we suggested they be re-used as a basis for a wider gravel focussed wheelset.
Not needing tubeless, the Hplusson Archetype is the logical choice. They are light, wide, nicely finished, and the braking surface is so smooth.
Of course, we used Sapim Race spokes on the front wheel, and Sapim Leader plain gauge spokes on the rear driveside to ensure lateral stiffness. Brass nipples help with ongoing reliability.
