Product Details

Zipp 303 S Carbon Tubeless Disc Brake Front Wheel

The use of a wide internal rim on the Zipp 303 S Carbon Tubeless Disc Brake Front Wheel allows wider tyres to be fitted for incredible ride quality. It's developed for riders that demand speed, be that on their road race or gravel bike, and is aerodynamically optimised for use with 28mm tyres but can also be fitted with any tubeless-ready tyres up to a massive 50mm width.

One of Zipp's lightest wheels, it weighs in at just 710 grams despite its 45mm depth and is constructed from unidirectional carbon fibres. The rim is laced to the 76D hub by 24 Sapim CX-Sprint spokes for a strong, stiff build, one that offers smooth rolling and punchy acceleration, while brass nipples add durability, perfect for all-condition riding and racing.

Designed to be used with disc brakes in a tubeless setup run with lower air pressure, fit this wheel and you'll benefit from faster rolling, improved comfort and a significantly reduced risk of punctures.

Highlights

  • Zipp graphics and cosmetic identity that scream speed
  • Fastest with 28mm, also fits wide gravel tyres up to 50mm wide
  • Wide rim optimises tyre profile to allow lower tyre pressure, especially with tubeless. The result is a larger contact patch for increased grip for confident cornering, descending, and handling in wet conditions
  • Lower tyre pressures and larger volume provide a compliant ride with fewer vibrations
  • Significant watt savings when running larger tyres at lower pressure
  • Wide hookless rims create a seamless transition to the tyre, reducing drag
  • 76 DB hub with Centre Lock interface
  • Only compatible with tubeless specific tyres

  1. Hello what tyres would you recommend for these wheels?

    Asked by Njw (Birmingham)

    1. Hi there, This will depend on what you are using the wheels for, Please see the link below to compatible tyres for this wheelset, https://support.sram.com/hc/en-us/articles/360050355593-What-tubeless-tires-are-compatible-with-Zipp-s-hookless-rims- Many thanks Joe W

  2. Hi, Zipp state these wheels can be used for gravel riding. Is there a 15mm x 100mm thru axle option for front wheel which is common on gravel bikes like 3T Exploro?

    Asked by Jon (West Yorkshire)

    1. Hello, This can be converted to 15mm, but would require additional adaptors, if you send us over an email to customercare@sigmasports.com then we can set up an order for you. Many Thanks Liam

  3. If these are tubeless only. Then what do I do if I get a bad puncture that the glue will not fix ? Normally I would just stick an inner tube in to get me home. Does it mean that it’s pointless carrying spare inner tubes now? Or co2 ? 

    Asked by Adam (Merseyside)

    1. Hi Adam, We would recommend a tubeless repair kit that should solve your problems. Dynaplug is the choice most of our staff make: https://www.sigmasports.com/item/Dynaplug/Racer-Tubeless-Tyre-Repair-Kit/LPSM This little unit will allow a tubeless tyre repair at the roadside.
