With Shimano's internal gearing, the shifting mechanism is tucked away inside the hub of the rear wheel, giving the bike an attractive, minimalist appearance, similar to a single speed or track-style bicycle. The introduction of the new Versa road shifter - developed specifically for the Shimano 8-speed internal hub - provides cyclists the first drop bar style integrated shift-brake lever for internally geared bicycles. With this innovative combination of technologies, the Dynamic Synergy delivers the performance and excitement of a true road bike, with the ease of operation and reduced maintenance achieved only with internal gearing.

Patrick Perugini, president of Dynamic Bicycles comments, "there is currently no other bike like the Synergy on the market, and no bike has ever offered this level of performance using an internally geared hub. The Synergy has an impressive gear range and clean, stylish good looks. But most importantly, it's just a lot of fun to ride. It really is an ideal bike for touring, event rides or fast commuting."

The Dynamic Synergy uses the Shimano 8-speed Alfine hub - Shimano's most efficient internal hub - and offers a gear range equal to 95 percent of a compact double crankset, and 92 percent of a full triple crankset. The Versa shifter has separate up and down shift levers and delivers smooth, consistent shifts that can be made at any time - while pedaling, coasting, or even at a complete stop. Versa's matching crankset features a highly efficient single chainring design that makes it easy to customize the gear range to match riding style and terrain. These components are mounted on a custom designed aluminum frame with a carbon road fork. The Dynamic Synergy weighs just 21 pounds, making it the lightest internally geared bike on the market today.

Perugini added, "Our mission is to make bicycling more enjoyable for more people - that includes all areas of cycling - from transportation to recreation. The Synergy is another example of how we are trying to attract new enthusiasts to bicycling by making bikes that are more fun to ride and less work to maintain."

The Dynamic Synergy retails for $1,399. The Synergy men's model is available in four frame sizes. A women's specific model is available in 3 frame sizes. The bicycles are available online direct from Dynamic Bicycles and through select outlets.
