Ironman Rules (World Triathlon 2024) Replicate (2025) have been used and approved by officials.

Ironman 2024 (World Triathlon)

Section 5.03 BIKE SPECIFICATIONS

(b) Protective screens, fuselages, fairings, or any other devices or materials (including duct tape) added or blended into the structure with the intent to reduce (or having the effect of reducing) resistance to air penetration are prohibited. Aerodynamic assemblies and protuberances on the head tube or elsewhere are prohibited. Provided that the use of adhesive tape (including duct tape) does not fundamentally alter or enlarge the general shape of the structure, adhesive tape may be affixed to the bike (e.g., to cover valve cutout of the rear disc wheel, to cover bolts
access, etc.); (DSQ)

Ironman 2025 (World Triathlon)

l.) Fairings are prohibited. Fairings are defined as any devices or materials (including duct tape) added, attached, or blended into the structure of the bicycle which have the effect of reducing the resistance to air penetration. Devices or materials (including duct tape) added, attached, or blended into the structure of the bicycle that does not fundamentally alter or enlarge the general shape of the structure, (e.g., to cover valve cut out of the rear disc wheel, to cover bolts access, etc.) are not affected by this rule).

l.) Fairings are prohibited. Fairings are defined as any devices or materials (including duct tape) added, attached, or blended into the structure of the bicycle “Bike frames are typically a double-diamond design, with a front triangle composed of the seat tube, down tube, top tube and head tube, and a rear triangle composed of the seat tube”, chainstays and seatstays. which have the effect of reducing the resistance to air penetration. Devices or materials (including duct tape) added, attached, or blended into the structure of the bicycle that does not fundamentally alter or enlarge the general shape of the structure, "the chainring guard and front derailleur guard do not fundamentally enlarge these areas" "and are not added to the structure of the bike"  (e.g., to cover valve cut out of the rear disc wheel, to cover bolts access, etc.) are not affected by this rule).

5.03 Ironman (World Triathlon)

(h) All aspects of the bicycle must be safe to the rider and to other athletes in the Race. Minimum safety standards include, but are not limited to, meeting or exceeding the standards of a reputable safety standards organization (such as CPSC, ISO, or other equally reputable safety standards organizations), properly glued and sealed tires, tight headset and handlebars, and true wheels; and (i) Non-traditional or unusual bikes or equipment are illegal unless, prior to the start of the Race, approval has been granted from the Event-specific Head Referee.

The head official from Ironman, “details can be given to an official” confirmed in 2024 that he has no issues with the EZ Disc and Chainring Guard and is happy for it to be used in Ironman races this was checked in 2024 after the new Ironman rules were released which fall in line with World of Triathlon and replicate the 2025 rules.

The front derailleur guard is a protective piece of equipment that
"Avoids power failure due to weather conditions with the front derailleur guard, it has also been designed so that it protects the derailleur from the wind & rain throughout the whole range of movement".

Why EZDisc and not Disc Wheel

Do not go for a cheap disc wheel as they have cheap hubs, we tested this
at Silverstone Sports Engineering Hub on the "rolling resistance
machine" you are far better of using a good quality wheel and adding an
EZDisc. We tested against the top end disc wheels on the market and ours
performed the same. You also do not have to buy two wheels, and you can take the EZDisc off on race day if needed and not have to carry two wheels abroad.
Apart from saving £1,000s it also is a lot more robust and not prone to damage
so can be used in all weather and training rides. We have over 8,000 EZDisc
customers and its being used by over 40 professionals one of the Pros is James
Teagle who would not use our EZ Disc unless it compared to his Disc wheel which
it did. Our aero data: https://ezgains.co.uk/pages/the-science everything else
is opinions all the hard data and facts are free for anyone to see Thanks 🏆

"Gains without the Cost"

The disc covers are compatible with the majority of road and time trial recumbent handcycle single speed track bikes with 406 650 – 700c wheels.

1) You will go faster using an EZ Disc regardless of speed. As an example, if you cycle 56 miles at 25kph an EZ Disc will save more time than someone cycling 56 miles at 40kph.

https://ezgains.co.uk/pages/the-science

2) It’s faster to use an EZ Disc on a hilly Triathlon, Time Trial course then a deep section wheel and has been proven on many occasions. This is why you will rarely see a high level athlete not using a Disc or an EZ Disc, even on courses such as Lanzarote and Nice.

3) EZ Disc adds to the structure of your wheel giving you more stability, and also adds to your bike handling ability.

4) In windy conditions an EZ Disc does not feel any worse to control then a deep section wheel. In fact, the reports show that it adds stability of the bike @that.tri.guy and many others have reported this. "Parcour Wheels" in windy conditions and a disc wheel are more stable than a deep section wheel. https://youtu.be/jbK6fW5F6X0?si=QgsxyJsZLZyKWrmX

5) The difference between a disc wheel and an EZ Disc is nothing on watt savings and speed..... Using a cheap disc wheel with a cheap hub or an old disc wheel, will be slower than using an EZ Disc with a wheel and decent hub.

6) Very easy to install and very robust unlike a disc wheel.

7) EZ Discs are legal for Cycling Time Trials and Triathlon.

The facts are there is no other ISO accredited "I brought this up as Ironman regulations quote about equipment being ISO accredited, or similar manufactures safety standard" x 3 Aero tested, Patent Protected, 5 year guarantee, safety tested, and Ironman approved disc wheel covers on the market. If your saving £1,000s why not get the best in the cost effective solutions available, the last thing you want is to have an accident on your bike.

"Please see below an example of how to inflate your wheel".

In nearly every case so far you do not need to remove your disc or any screws to inflate your tyre, or even use a valve extender, this is the same case with a CO2 canisters you just need to be a bit forceful, don't worry the EZDisc is extremely robust. If you find this is impossible then please feel free to contact us for advice, you also may need to consider a different valve length.

https://ezgains.co.uk/pages/ez-disc-fitting-instructions

Please measure the full depth of the rim, this is from the top to the bottom excluding the tyre, towards the centre of the wheel were it meets the spokes, includes the brake track.

Measure the rim not including the tyre this is the top to the spoke.

The 650B is mainly for extra small bikes like the Canyon Speedmax and any bike larger then this are 700c.

The 700c is around 622mm in diameter. "not including the trye and to the edge of the rim to rim.

650B (585mm) being 18mm larger in diameter than 650C (571mm)

This product has been wind tunnel tested at (Silverstone Sports Engineering Hub) and is as fast as a top end disc wheel. The EZDisc has all the aero benefits of the EZDisc SL its just 1/3 heavier on average around 200g. - please see science page

Some people would suggest to remove a disc wheel or disc covers in windy conditions, however the wind actually increases the effect of the disc and therefore your speed. So we would say, never take it off and practice in the wind.

In windy conditions an EZ Disc does not feel any worse to control then a deep section wheel. In fact the reports I have had back, again say this has added to the stability of the bike @that.tri.guy and many others have reported this.

Rim tape (electrical tape) can be put between where you wheel meets the disc cover. This helps to protect from any marks being formed due to the friction between the wheel and disc cover.
Simply put a pencil line around the disc on the wheel and overlap your rim tape (electrical tape) on this line.

Please look at instructions

https://ezgains.co.uk/pages/ez-gains-fitting-instructions-for-rimtape-and-binding-screw-covers

This is not strictly needed but is believed may give you an extra marginal gain.

You can use the rim tape around the wheel to protect it, or you can use the electric tape and use the rim tape supplied for the outside.

An easy way to apply the rim tape or electrical tape is place the EZ Cover on the wheel in a central position and draw round this with a pencil and then overlap this line with the tape or rim tape by about 3-5mm to protect the wheel.

https://ezgains.co.uk/pages/ez-gains-fitting-instructions-for-rimtape-and-binding-screw-covers

Again, this is not strictly needed but is believed may give you an extra marginal gain, but can help hold your screws in place - please look at fitting instructions.

https://ezgains.co.uk/pages/ez-gains-fitting-instructions-for-rimtape-and-binding-screw-covers

The binding screws should pinch the disc tight against the wheel, but not pull the disc in.

If you feel you could use a shorter or longer binding screw, please contact me and I will send some out.

Chain whip and a cassette remover only. If you have a wheel with disc brakes, you will also need to remove the disc calliper which is usually removed using a cassette remover.

Please refer to our detailed Fitting Instructions for each of our products via the top menu.

The rim brake version will not work on a disc brake, this is because a disc brake wheel is shaped different due to the brake calliper. There is a small chance the disc brake version will work on some rim brakes.

Everything you need to set up your EZDisc:

– Disc Covers
– Binding screws
– Cable ties
– Electrical tape
– Valve covers

Both disc and rim brake versions are domed differently due to the design of the spoke positions. We have had occasions where people have managed to get the rim brake covers to fit the disc brake wheels too, but it's very rare that this works without issues. A rim brake will never work on a disc brake. We recommend that you purchase a cover for the wheel you are most likely to use it on.

https://ezgains.co.uk/pages/ez-disc-fitting-instructions

https://www.youtube.com/watch?v=AOTawSColHU&t=2s

Follow picture instruction for fitting.

Disc Warping:

Cable ties should be wrapped around one spoke and two holes with a minimum of 5 cable ties, this should be hand tightened and not pulled so tight it indents the disc. The main cause of warping is the binding screws are to tight, please select another size provided, in most cases we proved you with the correct size screw for you wheel, if you find its still not work try using a mix of the size screw failing that contact EZGains for advise.

Screws coming loose:

The binding screw covers are provided and advise to use these, only hand tight the screws, make sure you haven't caught the EZDisc between the screws. If the cable ties are to loose this will cause movement on the EZDisc and lead to screws possibly coming loose and cable ties snapping.

• Please ensure you centralize the EZDisc.
• The valve does not need to be exactly in the middle.
• You can just use a track pump or CO2.
• Derailleur rubbing on EZDisc 9/10 times the derailleur is bent or you have to micro adjust your Derailleur.
• 12 Cassette speed we have found that on a rare occasion you have to use a 0.5mm cassette spacer on the inside.
