Its classic road geometry offers a balanced feel—lively on climbs and composed on descents—while the Shimano Dura-Ace 11-speed groupset ensures crisp, reliable shifting and braking. Finished with clean welds and understated style, the RT-2 is a refined, long-lasting platform for riders who value ride quality, craftsmanship, and all-day comfort.
