Spectrum Cycles was originally founded to produce the highest quality custom steel and titanium frames and bicycles in the world. With this singular goal, Spectrum founder and president Tom Kellogg began building frames under the Spectrum name in 1982. In 1985 Tom employed Master Signature frame builder and long-time friend Jeff Duser.

Today the Spectrum facilities are housed in a 185-year-old stone barn located in the heart of the Lehigh Valley of eastern Pennsylvania. At Spectrum, Tom and Jeff are still dedicated to the design and construction of the finest custom steel and titanium frames and bicycles available.
