The 303 Firecrest Tubeless Disc brake wheels were designed using real-world direct measurements (vs. primarily wind tunnel or computer simulation). This included Zipp’s RollingRoad™ Testing Protocol. The results were huge. Its rim is slightly more bulbous in design than its predecessor, with a 30mm outside width, a 25mm internal width and a 40mm rim depth. The profile provides low drag and an improved transition between rim and tyre, boosting aero efficiency on the road.
These wheels are faster, lighter and more capable over varied terrain, whether the surface is tarmac in all its conditions or no tarmac at all. Deeply rooted in Zipp’s drive to conquer the Spring Classics, the revised 303 Firecrest is redesigned with a purpose-made approach for the demands of modern road bikes. This is the first Zipp wheelset to feature TSE™ Technology (Total System Efficiency). The 303 Firecrest’s precise rim layup results in greater all-around efficiency for greater speed through reduced wind resistance, rolling resistance, a lower weight, increased durability and vibration losses.
The wide rim stance also features less tyre deflection for reduced rolling resistance. The combination of the wider tyre, increased tyre volume and lower tyre pressure reduces rider fatigue. This is because the ride is smoother over imperfect surface conditions as the tyre and wheel system absorbs the shaking, not the rider. At the centre of the 303 Firecrest Tubeless Disc brake is a versatile and durable hubset, the German-engineered ZR1 DB. This hubset features 66 points of engagement for quicker pedalling response.
The 303 Firecrest Tubeless Disc-brake wheelset is for those after greater efficiency for greater speed. The payoff is a smoother, faster ride.
