City Bicycles – Jhonatan Moloon owns and operates City Bicycles in midtown Manhattan. Jhonatan has helped me considerably in all purchases, from clip in shoes to the bike and installing any additional components. Cannot recommend this shop enough!
The Touring Store – Wayne is based out of Fort Collins, CO and specializes in Tubus racks and Ortlieb Panniers. He knows how each rack will fit almost any bike and if modifications are necessary. He is extremely thorough in all responses and typically runs specials on large purchases.
