2005 Iron Horse Adventure GLX The GLX Hybrid uses 700c rims categorizing it as a hybrid. I consider this bike more of a fitness than a comfort hybrid. Typically fitness bikes have road brakes, but the GLX comes stock with powerful mountain V brakes. Consider this bike if you're looking for a road bike that puts you in a more upright riding position. SIze 15" fits riders 5'-5'6" tall. The Iron Horse Team Yellow is bright and is actually a yellow pearl!
