The Retrotec Gravel frame is designed for mixed-surface riding, long days, and varied terrain, balancing modern capability with distinctive style. Every frame is hand built by Curtis Inglis in Napa, California, using modern geometry, components, and tubing.
Production frames are made to order, not in stock. Each frame is built by hand using standardized sizing and options to keep the process simple and accessible. Typical lead time is 12-14 weeks from deposit. For the most current estimates, see the FAQ.
Production frames are ordered with a non-refundable deposit, which secures your place in the build queue and is applied toward the total frame price. After checkout, Curtis will reach out within 48 hours to confirm order details and finalize remaining options.
Every Retrotec frame is built by hand in Napa, California, with a focus on local production, direct collaboration, and hands-on craftsmanship.
