131 Catania CS-Cart P 0 <p class="MsoPlainText">The new Catania features carbon fork, carbon seatpost, Ultegra derailleur, and the new Fezzari Racing Design R3A frame with increased aerodynamic properties and a sleeker look.</p> <p class="MsoPlainText">The Catania road bike is a great all-around bike. If you want to get into road biking or want a bike that is durable, high-performing, and as comfortable as a road bike can get, the Catania is for you.</p> <p class="MsoPlainText">The Catania features the R3A frame with compact geometry. Compact geometry means that we shorten the seat tube slightly, which makes the bike a little lighter and reduces lateral flex (you don&rsquo;t want your bike flexing side to side when you&rsquo;re pedaling). It also allows your riding position to be a little more upright.</p> <p class="MsoPlainText">Add to that a great set of components, including: Shimano Ultegra derailleur and Shimano 105 shifters for smooth shifting Fezzari Carbon II fork to minimize the road chatter; FSA Gossamer crank with external oversized bearings that make it pedal smoother and more efficiently; Alex double-wall rims that are extremely durable; Maxxis performance tires; and a Fezzari Racing Design Ultra XR saddle that is one of the most comfortable road saddles you&rsquo;ll ride.</p>
129 Fore CR1 CS-Cart P 0 <p>Take your riding to the next level with the For&eacute; CR1 full carbon road bike, built to be extremely durable and responsive. Feel the adrenalin rush as it accelerates smoothly and corners aggressively. Great for cross-country riding, a triathlon, and even a race.&nbsp; The new Fezzari Fore CR1 is the newest bike to the Fezzari carbon road bike family.&nbsp; It has the same tried and true monocoque carbon frame as the&nbsp; Fore CR2, but is built with a Shimano 105/Ultegra groupo to help save a little on the price.</p> <p>Start with a proprietary Fezzari Racing Design Xr4 monocoque carbon frame that was recently tested as one of the most durable frames on the market.</p> <p>All this translates into exhilaration when you&rsquo;re climbing &ndash; knowing that you&rsquo;re ascending more efficiently &ndash; and confidence on the downhill when you take that corner at high speeds. Our proprietrary frame painting process give one of the best looking finishes available.</p> <p>You get e&nbsp; upgrades over the Catania:</p> <ol> <li> <strong>Upgraded Frame</strong> &ndash; the CR1 has a full monocoque carbon frame vs the Catania&rsquo;s aluminum alloy frame. The carbon frame is lighter and will absorb more of the road chatter when riding.</li> <li> <strong>Upgraded Seatpost</strong> &ndash; the larger diameter 31.6mm seatpost is stiffer and lighter.</li> <li> <strong>Upgraded Wheels</strong> &ndash; The CR1 gets a lighter and more aero dynamic wheel whith looks to go with it.</li> </ol> <p>Who will want this bike? If you&rsquo;ve been biking and plan to get into it more, and you want to get something that will grow with you as you grow in the sport (but you&rsquo;re not willing to pay the price of a CR3 or CR5), then this is the bike for you. It gets you on a full monocoque carbon fiber frame and still gives you the confidence you won't miss a shift with the Shimano 105/Ultegra drivetrain. You&rsquo;ll have the confidence that you can ride with anyone, anytime.</p>
