EZDisc Trouble Shooting

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.

Truths and Facts

1) You will go faster using an EZ Disc regardless of speed as long as you cycle over 25kph. If you take longer to cycle a distance an EZ Disc will save more time then someone doing it faster.

2) EZ Disc adds to the structure of the your wheel giving you more stability and adds to your road handling ability.

3) 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.

4) The difference between a disc wheel and an EZ Disc is a matter of seconds over 40k.....But using a cheap disc wheel with a cheap hub, will be slower then using an EZ Disc with a wheel and decent hub.

5) Very EZ to install and very robust unlike a disc wheel.

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

IRONMAN/ETU/ITU RULES Chainring Guard & Derailleur Guard

Just to confirm that, since the new rules have come into force we have had no issues with
the Chainring Guard 3-5
Watts saving and Front derailleur guard 2-5.8 Watts saving and we have not received any
negative feedback from any athletes competing and no issues with the officials across Ironman/ITU/ETU races.

We have since been in talks with a head
official at Ironman and he does not have an issue with the chainring guard
after talking with World of Triathlon, the front derailleur guard will have to
go to committee and the worst case scenario is they ask for a 3 year phase out
period, as the products we offer follow ISO accreditations and have already
been on the market prior to new rules and are deemed as a safe product and
commercially available from a reputable company.

The discussion I had with the head official, lead me to
believe they are trying to eradicate unsafe home-made products and unsafe
cheaply made products by non ISO accredited companies please see…

 (g) 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)

Triathlon (formerly ITU) writes rules regarding equipment legality and
therefore is the only entity who can declare equipment legal for use in all
sanctioned triathlons. The IRONMAN Competition rules are based on the World
Triathlon rules and I have always deferred to World Triathlon for equipment
legality questions when uncertain about the legality of equipment. Because
equipment is evolving quickly and there is currently no list of equipment that
is legal for use in triathlon, game-day decisions on equipment used in
triathlon events, including IRONMAN events, may need to be made by the event’s
Head Referee. If any athlete questions the decision of an IRONMAN Head Referee,
they can call me to provide background and I can chime in with input/feedback.
However, in the case that the Head Referee is not able to get an answer from
World Triathlon before the event start, the ultimate decision is theirs to
make. In my opinion, based in part with a conversation I had with World
Triathlon (who, while not providing formal approval, did show concern for this
piece of equipment during the conversation) – I see no issue with the EZ Gains
chainring guard and consider it to fall within current rules. However, I did
not hear comments from World Triathlon regarding the EZ Gains front derailleur
cover. Therefore, because my opinion on this equipment is uncertain, I
personally feel that some referees MAY feel that the front derailleur cover is
in violation of the fairing rule. Therefore, I doubt that you will have an
issue with the front chainring cover, but you MAY get questioned about the
front derailleur cover. If you are questioned about the front chainring cover,
feel free to call me I will share my opinion with the event’s Head Referee,
that it is legal, and encourage them to speak to World Triathlon if they still
have concerns. If you are questioned about the front derailleur cover, give me
a call and I will encourage the event’s Head Referee to ask World Triathlon
whether or not they deem it legal. Give me a ring if you want and have a great
