At The Center Of The 303 Firecrest Tubular Is The 77/177 Hubset, An Innovation That Results In enhanced Stiffness, Durability, Simplicity & Versatility. Zipp’s Original 303 Made History By Becoming The First Carbon Wheelset To Win Cycling’s Two Most Famous Cobbled Classics, Paris-Roubaix & The Tour Of Flanders. The 303’s Wider Rim Provided Extra Durability, & enhanced Aerodynamics. That Wider Rim Also Led To The Development Of Our Revolutionary Firecrest Platform Platform That Further Reduces Aerodynamic Drag While Increasing Crosswind Stability.

Product Note: The Wide Profile Of The 303 Firecrest Is Crucial To Zipp’s Revolutionary Firecrest Technology Used To Create Wheels With Superior Aerodynamics As Well As enhanced Stability & Handling. The Rear 303 Firecrest, However, May Present Some Fitment Issues For A Small Number Of Road & Triathlon Frames. The Clearance Between The Chainstay & The Rim May Not Be Adequate To Avoid Contact Between Each Other When Ridden Under Load. We Urge Customers Who Plan On Riding The 303 Firecrest To Test The Wheel Within The Frame In Which They Intend To Ride, Under Normal Riding & Road Conditions, Before Purchasing. Clearance Within Individual Frames Of The Same Size, From The Same Manufacturer, May Vary. That Is Why It Is Imperative That You Test The Wheel In Your Frame, Or In The Frame That You Are Considering Purchasing. Customers Who Run Into This Fitment Issue May Select Any Other Spoked Wheel Within The Zipp Lineup As An Alternative, Including The 404 Firecrest With Its Narrower Aero-Width Profile. Specs: Weight
