The guys down at Trek in Sinsa are true professionals. They take pride in their work, are knowledgeable about their craft, and provide a level of customer support and coaching that you need in you bike repair partner. It’s easy to sell amateur riders repairs they don’t need but these men are professionals and tailor their services to their customer. I’ve been visiting them for all of my maintenance since moving to Korea and couldn’t be happier. Keep it up gentlemen!
