131		<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’t want your bike flexing side to side when you’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’ll ride.</p>				<p class="product-promo-text"><span class="product-promo-header">FREE US shipping over $100!</span><span class="product-promo-body">Orders within next 2 days will be shipped on Monday</span></p>
