Zipp 303 Firecrest Carbon Tubeless CL Disc Wheel : REAR XDR

Brand:Zipp

Code:ZPWH8530001

Zipp’s 303 Firecrest Tubeless Disc-brake wheelset is designed for the real world : imperfect conditions, road surfaces, and elements where the bottom line is simple. Efficiency = speed. It’s faster, lighter, and more capable over varied terrain—whether the surface is tarmac in all its conditions or no road at all. Deeply rooted in Zipp’s drive to conquer the Spring Classics, the new 303 Firecrest is recreated with a purpose-made approach for the demands of modern road bikes. When it comes to going fast on a bicycle, efficiency means reduced Wind resistance, rolling resistance, rider fatigue and weight.

The 303 Firecrest Tubeless Disc-brake was designed using real-world direct measurements (vs. primarily wind tunnel or computer simulation). 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. 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 helps to reduce rider fatigue by smoothing out the ride over imperfect pavement and road conditions — the tyre and wheel system absorbs the vibrations rather than the rider.

At the center of the 303 Firecrest Tubeless Disc brake is a versatile and durable new hubset, the German-engineered ZR1 DB. This hubset features 66 points of engagement for quicker response. The 303 Firecrest Tubeless Disc-brake wheelset is for dedicated cyclists who aspire to the latest in technology; in races, against peers, or simply conquering personal limits. This is about becoming faster and matching your motivation to the most advanced technology.

The 303 Firecrest is a hookless bead designed for Tubeless specific tyres and is optimised for a 28mm width. Like all hookless rims, the wheels can be used with tubes but only within the recommended tyre pressures for the rim and only when used with a tubeless specific tyre.

 

Features:

  • New Zipp graphics and cosmetic identity that scream speed  
  • Versatile endurance wheelset for the modern road bike with tubeless and hookless rim profile  
  • Lighter Weight than its predecessor, making it nimble and fast.  
  • Tubeless Made Easy, optimised tyre bed design allows for simple tool-free installation and removal with no need for an air compressor to seat the tyre. 
  • Ultra-wide 25mm rim profile creates a better tyre interface to be fast on or off the road  
  • New 40mm rim depth makes a light and aero wheel in every situation  
  • New ZR1 DB hub is engineered in Germany with better seal design for improved durability and quicker response with 66 points of engagement  
  • Ships with 12mm front and rear end caps  
  • Center locking rotor interface. Lockring is included with the wheels 
  • XDR™ or SRAM/Shimano driver bodies  
  • Campagnolo driver body sold separately

    ABLC

    Advanced Boundary Layer Control (ABLC) refers to the patented and instantly recognizable dimpled pattern found on all of our carbon rims. ABLC smoothes airflow across the rim's surface and is tailored to every model from the 202 to the Super-9 Disc. The third-generation of ABLC has up to four times more dimples than before.

    AeroBalance

    Zipp’s sole mission is to help you go faster. That's why their wheels are race-ready before they're camera-ready. For years, Zipp has used a combination of testing methods – wind tunnel, CFD computer simulations, pro athlete evaluations, on-road testing, and the RollingRoad ride simulator – to refine aero performance to new levels of excellence. Over the decades of innovation, their engineers have learned to look beyond just focusing on simply reducing aero drag. Instead, the goal now is to reduce aero drag while also minimizing the effects of crosswinds on handling. This optimizing of aero efficiency and crosswind stability became known internally at Zipp as AeroBalance. The approach began with Firecrest technology and has been advanced with the introduction of the NSW lineup, especially with the Sawtooth technology found in the 454 and 858 NSW. Sawtooth accomplishes this with a series of patented fin-shaped Hyperfoil nodes along the inner diameter of the rim that work together with our new HexFin ABLC dimples for improved airflow.

    TSE Technology

    Zipp’s TSE Technology (Total System Efficiency) was developed by engineers in the Nest Advanced Development Lab in Indianapolis. This approach to carbon-wheel manufacturing means the 303 Firecrest’s precise rim layup results in greater all-around efficiency for greater speed through reduced wind resistance, rolling resistance, gravity (weight + durability), vibration losses

  • Zipp 303 Firecrest Carbon Tubeless CL Disc Wheel : REAR XDR review by James, on 24/10/2022

    The ‘cross riders choice and an excellent one. Fast and light with astonishingly reliable tracking through corners. Ride feels totally controlled across rubbish terrain, which fills you with the confidence to throw the bike around a bit. Excellent service as always from the 7hundred team. They know their stuff and really go ‘above and beyond’.

    Outstanding wheels: light, smooth, quick hub engagement and fast both on the flat and through climbs. All this while still feeling very robust and confidence inspiring for tough off road CX and gravel use. Running wide hookless rims with wide tyres and low pressures makes sense both on and off road. I was unsure about the move to hookless, but the 7hundred guys took the time to explain the new technology and the merits of wider rims. I’m now sold on the concept. This is where you really get the benefit of highly experienced 7hundred team. They are always spot on… they know the products they sell and offer excellent qualified advice as cyclists themselves. Keep up the brilliant work!
