They have continued to build tough, long-lasting, and fun bicycles with frames suited to each rider, and with the ability to install a variety of parts.Surlyis a well-known manufacturer of bicycles made by such unparalleled bicycle enthusiasts.
The KRAMPUS is the origin of the new 29+ genre, and its 29 x 3.0" ultra-thick tires give it unparalleled traction and float, making it ideal for trails, touring, and bikepacking.
