John Castellano is not one to be satisfied with existing technology. John has a background in aerospace engineering and suspension design, and his passion is pushing the envelope of bicycle design in bold, new directions. John recently returned to his alma mater, MIT, to delve into the latest techniques in pivotless design.
The SilkTi Pivotless Titanium Softtail is an example of John’s out-of-the-box thinking. The patented Flat Plate Chainstays give you double the travel and more lateral rigidity than any other softtail.
Each SilkTi is individually hand-built to order in collaboration with Hall of Famer Steve Potts. They can build you a classic 26er, a SilkTi 29 or a mutant SilkTi 50/50 with one of each. Castellano and Potts combine aerospace engineering and materials with old-world craftsmanship to build some of the finest full-suspension mountain bikes available.
Castellano’s latest offering is Zorro, son of Szazbo—the only long-travel single-speed on the planet. It’s a bike for single-speeders who want a suspension bike and for suspension lovers who want to try single-speeding. It even inspired a new equation: Big Travel + Big Wheels = Big Fun! Handmade by Castellano and Steve Potts from U.S. True Temper OX Platinum.
