Product Description

For when every gram counts. The Continental Grand Prix Supersonic is a lightweight tyre that offers exceptionally low rolling resistance with plenty of grip in the corners. This is an out and out race tyre for road and track where lightweight counts more than puncture protection.

Key Features:

  • Rubber Compound: Black Chili compound for low rolling resistance and sensational grip
  • Casing: Supersonic casing for the ultimate speed
  • Weight: The lightest clincher tyre on the market, from 140g
  • Design: Slick tread & super fine 310 tpi casing
  • Best for: Designed purely for the speed of competition, ideal as a track clincher as well as short road events
  • Weight: from 140g

Fit the Grand Prix Supersonic, coupled with a Race28 Supersonic tube and you've got a superlight and speedy tyre combination on the market at just 200g.

The Grand Prix Supersonic offers exceptionally low rolling resistance that rivals that of our renowned tubulars. The tyre is now even faster thanks to the new Black Chili compound which utilises nano particles of carbon to create a molecular structure of the rubber compound which is stronger, faster and grippier than previous compounds.

Our super-fine, polyamide casing combined with a thin layer of Black Chili rubber is extremely lightweight and is designed to allow high inflation pressures.

This tyre is intended for race use only in solo events on the road or as an all-round track clincher (indoor & outdoor), and is not recommended for road races or training rides due to its short tread life. There is no extra puncture protection with the Grand Prix Supersonic due to the lightweight construction. Riders should weigh up the compromises that they are willing to take before selecting this tyre

How to check your current tyre size?

Take a look at the sidewall of your current tyres and you’ll see one or two sets of figures;

One is the traditional size like 700x28c or 27.5x2.2. The first figure is the tyre diameter(size). The second is tyre width. Note: road bike sizes are in mm, MTB sizes are in inches.

The other set of figures you may see is ETRTO sizing like this 28-622. The first number here is tyre width while the second number relates to wheel diameter.

Here is a comparrison chart for traditional and ETRTO sizing to help you choose the correct tyre size.

Will this tyre fit my wheel?

Your new tyre must be the same diameter as your current one (to fit your wheel rim).

Then, you need a choose a tyre which will fit your frame.

Road bike tyres are generally 21 – 28mm wide

MTB tyres can range from 1.5”-5”

To make things complicated road tyres are measured in mm, while MTB tyres are in inches.

How wide is too wide

You want to leave at least 4mm clearance between your frame and tyres to prevent rub and allow for mud clearance.

Measure the following areas on your frame:

Fork crown (top)

Brake calipers (make sure you squeeze them)

Chainstays

Seatstays

Subtract 4mm and you’ll have the maximum width your frame can handle.

Continental Road Bike Tyre Guide

With over 100 years of manufacturing experience, Continental road bike tyres have been tried and tested at the very highest level. See the range of technologies that give their clincher and tubular road bike tyres a performance edge.


Compounds

Black Chili Compound

Black Chili is Continental’s premium rubber compound for both road and mountain bike tyres. It offers more grip with less rolling resistance and even lasts longer than other rubber compounds.

Continental Black Chilli

Pure Grip Compound

Pure Grip is a performance rubber compound that sits just below Black Chili. An Activated Silica rubber compound, Pure grip offers excellent traction, is also long lasting and highly durable. Used on both road and mountain bike tyres, Pure Grip is produced in Continental’s Chinese factory.

Tyre Types & Protection

PlusBreaker

These tyres offer the highest level of puncture protection against objects piercing the tread. Plus Breaker is a layer of special highly elastic rubber sits just underneath the tread. This successfully stops all types of foreign objects from getting through to the inner tube below. Even a drawing pin can’t get through the PlusBreaker layer.

Continental PlusBreaker

PolyX Breaker

PolyX Breaker is a densely woven Polyester fibre layer that sits beneath the tread of the tyre. The polyester fibre layer is tightly woven crosswise and is extremely resistant to foreign objects penetrating through the casing. This puncture reducing technology does not adversely affect rolling resistance.

Continental PolyX Breaker

Vectran Breaker

Vectran breaker represents the pinnacle in puncture protection. Highly resistant to puncture and cuts, Vectran breaker doesn’t slow the tyre down. Vectran is a liquid crystalline polymer (LCP) that is spun from Vectra liquid polymer and processed into a multistrand thread. Vectran has an enormous tear resistance at a very low weight and offers the ultimate under-the-tread protection.

Continental Vectran

DuraSkin

DuraSkin is an ultra-lightweight cut resistant sheath that wraps around the tyre casing. Designed to protect the sidewalls and tread from actual cuts and slashes on the road, this technology is found in all Gatorskin tyres. DuraSkin tyres stand out with their brown sidewalls.

Continental DuraSkin 4c

Hardshell

With a wider PolyX breaker layer combined with DuraSkin sidewalls, Hardshell-ProTection offers outstanding puncture protection. The three-ply layer with 60 TPI carcass covers the entire tyre and makes it a real bastion against urban detritus. Hardshell tyres are the flagship puncture protection racing tyres.

Continental HardShell

Supersonic

Lightweight for maximum acceleration, Supersonic tyres are ideal for track and time trials.

Continental Supersonic

NyTech Breaker

Sitting between the SafetySystem and PolyX Breaker, NyTech offers more effective puncture protection for performance tyres. The Nylon fabric is highly resistant to cuts and punctures but offers low rolling resistance and reduced weight.
