Our full carbon rear disc wheel is perfect for use in both time trials and triathlons. The Disc maximises speed whilst minimising drag making it our fastest wheel for use against the clock. The Disc can be paired with either a Passista or Chrono front wheel for maximum speed come race day.

The Disc is our fastest wheel against the clock for time triallists and triathletes. This full carbon disc wheel is designed to maximise speed while minimising drag. The Disc is tubeless-ready and has an internal width of 17.5mm and a revised internal rim profile. This allows a rider to run a wider tyre at a lower pressure for comfort.

With an internal width of 17.5mm, and a revised internal rim profile, the Disc is tubeless-ready. A wider tyre is the perfect match for the Disc allowing riders to choose to run a lower tyre pressure, giving a smoother, more comfortable ride whilst also reducing rolling resistance.

The updated textured braking surface uses an industry-standard high TG resin to ensure that braking performance remains consistent and predictable at all times. Meanwhile the all new precision-machined alloy hubs are fitted with high-grade EZO cartridge bearings to deliver smooth running in all conditions.

Aerodynamics

Aerodynamics is at the heart of what we do at Parcours. We have spent countless hours over multiple sessions in the wind tunnel to provide the level of data that you as the rider need to make an informed decision. We strive to be completely transparent with all our development and testing, whilst keeping things accessible to all our riders.

Braking Performance

As with our aero testing, it’s important to take into account real-world riding conditions. Parcours wheels have been tested across all terrain, ranging from short, sharp Lake District downhills in the rain to long, sweeping Alpine descents in summer heat. Each time they performed admirably, with no unpleasant surprises or issues.

Braking Tips

So what does all the testing tell us, particularly about braking on Parcours wheels? Ultimately, our goal is to keep the rim temperature down, meaning we steer well clear of the critical glass transition temperature. To do this, you can employ a number of techniques:

• Most importantly, don’t drag your brakes all the way down a descent. Starting with smaller, controlled downhills, build up your confidence to release the brakes and fully enjoy the feeling that you’ve earned on the uphill
• nstead, use a brake/release method, often referred to as “pumping” your brakes. Even a short release allows the rim to cool significantly
• Alternatively, you can alternate between your front and rear brake when looking to reduce speed
• Ensure that your brake pads are "toed in" so that the front of each pad contacts the wheel when the brakes are applied. This will help to reduce any juddering feel under braking, as well as any brake noise
• Make sure to regularly inspect your brake pads and clean away any debris. Note that your rims may become slightly discoloured from brake pad residue. This is completely harmless

Maximum Tyre Pressure

Note: for road use we recommend a 23mm or 25mm tyre, up to a 28mm tyre for the Strade

Please note that carbon brake tracks are designed to be durable and long-lasting. If well- maintained and cared for, you should expect many happy years of use before the rims need replacing. However, brake track wear will be accelerated in wet weather, when all sorts of nasty grit and dirt finds its way between the brake track and brake pad. It’s worth giving the brake pads a good clean after a wet ride. The finish on the brake tracks will change over time – this is perfectly normal and not a cause for concern.

Weight Limit

There isn't a hard and fast max weight that we'd rate the wheels at as it's largely dependent on the sort of riding you're doing. As you can imagine, a heavier rider on a smooth road isn't directly comparable to a heavier rider on rough roads.

Saying that, with an 18 spoke front / 24 spoke rear lacing pattern (24/24 for our disc brake wheelsets), if you're over 90-95kg then we'd suggest looking at increasing the spoke count to make the wheel a little more robust. Get in touch to discuss the custom build options available.

Warranty

It’s important to us that you feel confident in your purchase, which is why we offer a full 2 year manufacturer’s warranty on all Parcours wheels. This covers any manufacturing or workmanship defects. If you have an issue, simply get in touch and we will arrange shipping back to us where individual parts will be replaced or repaired as required.

This warranty is only valid for the original purchaser and does not include any third parties. Original proof of purchase may be required.

This warranty does not cover:

• Normal wear and tear, including cosmetic
• Crash damage (see our separate crash replacement offer below)
• Products which have been incorrectly installed and/or adjusted

Furthermore, this warranty will be invalidated if:

• The product is used outside of normal usage or is damaged by rider error
• The product is modified in any way
• Tyre pressure exceeds limits laid out below
• Non-carbon specific brake pads are used (with the exception of Paniagua alloy rims)

Crash Replacement

If the worst happens and you find yourself anything but rubber-side down, we want to help you get back on your bike as quickly as possible. If your wheels are damaged in a crash, we will offer :

• A substantial discount on any replacement rims
• Wholesale pricing on any other replacement parts
• A word of encouragement to get going again, along with a touch of sympathy. We've all been there!
