We inventory the Tomac Diplomat frame for the simple reason that the frame is a joy to ride. Cycling legend John Tomac concurs by stating he has more fun riding the Diplomat than any of his other bikes. Short chainstays allow the front end to pick up easily and the wheels want to roll over everything.
The Diplomat is aptly named because die-hard 26" riders find it nimble and efficient to ride. This is due mainly to the short, 17.5" chainstays combined with an IAS suspension system that does not compromise efficiency or rear end stiffness. With IAS, a CNC machined link between the rocker pivot moves on high-end bearings. It allows the rear shock to initiate more quickly and the suspension to be more responsive. IAS suspension makes quick work out of bumps, especially repetitive hits where quick suspension action means less transmitted to the rider.
Another major factor in big-wheeled bikes is getting adequate stiffness in the frame. The Diplomat uses a fully triangulated rear swingarm to increase stiffness. Stiffness in the swingarm translates both into better rider control, but it also allows the suspension to be more active in rough terrain. The front triangle has also been designed with stiffness in mind. The top and down tube are specially shaped and are triple butted for low weight weight.
Build information: requires a Shimano direct mount front derailleur, 29 inch wheels, designed for 120mm travel, tapered fork, 30.9mm seat post and standard English (BSC) threaded bottom bracket
