Please read the Giro crash replacement policy.
I broke my buckle, can I buy a new one?
Yes, please order one from your local Zyro retailer. Please refer to the attached chart to identify which one you need.
I damaged one of the threads where the cleats are bolted to the sole, what can I do?
The cleat hardware is replaceable and can be ordered from your local Zyro retailer. To replace, remove the insole from the shoe and carefully use a sharp blade to cut the perforated flap in the felt. Lift up this flap to access the cleat hardware and replace.
The threaded cleat nuts in the sole of my shoes seem wobbly, is this normal?
The cleat nuts are simply a piece of metal that sits in a solid recess in the sole of the shoe, this is so they can’t rotate when fitted to a cleat. These are not glued into the sole and they can be replaced easily. If the nut is sitting properly in its recess then it will firm up when the cleat bolts are tightened.
I’ve got wide feet, what do you recommend?
Some models are available as ‘HV’, so they are higher volume, particularly in the forefoot area. If you usually have to ‘size up’ when buying footwear because they are too narrow, then the ‘HV’ models may be better.
How can I figure out my size?
We always recommend that you visit a retailer and actually try shoes on, because not all manufacturers’ shoes fit the same and every person’s foot is so different. We use Euro sizing because the increments between each size are smaller than UK sizing, so the fit is more likely to be closer to your perfect fit. Half sizes are also available in some models. Please view our size chart as a starting point, but it’s always best to try before you buy.
What is the stack height of Giro road shoe outsoles?
Nylon soles are 8.4mm and carbon soles are 6.5mm.
How do I know which size arch support to use with my Supernatural Fit Kit?
We would recommend that you use the support which you feel is the most comfortable. You get multiple sizes in the box so you can try them all.
What is a neutral platform?
This means that there is no tilt or permanent adjustment build into our shoes. By maintaining this neutral platform, riders who require custom orthotics will not need to compensate for any unnecessary or improper adjustments that can compromise the fit or performance.
As you may be aware all warranty claims lie with the shop from where the item was bought therefore our first suggestion would be to contact the shop directly about any warranty issues. They will be able to advise you how to return it to them to look at it under warranty. This also includes mail order and internet companies.
We recommend that you change your helmet every three years. Helmet design, fit and comfort improves at a fast rate so by keeping up with the latest technology, you’ll be wearing the best vented, most comfortable and safest helmet available. Over time a helmet can pick up lots of small knocks and bumps that cumulatively can affect the performance in the event of an accident.
We aim to keep as many spares available as possible. For a current helmet model, spare pads and visors are available. For a discontinued models we aim to keep spares available for 3 years after it has ceased production
We do not recommend replacing straps on your helmet. On many of the helmets the straps are anchored into the internal roll cage as part of the design and are not replaceable.
Yes. Position the helmet carefully and double check that the straps are in the correct place. You can cut the excess off with a sharp pair of scissors and seal the end with a hot iron to prevent fraying.
Three size helmets are available on the more performance orientated helmets to enable a wider range of head sizes to be incorporated in one model. Our Unisize helmets are available in specific Youth, Adult, Women's and XL sizes.
The XL size helmet accommodates a 65 cm size head.
Giro does not recommend paints or solvents of any kind be used on the helmets. They can damage a helmet so that its protective capabilities are significantly reduced.
Your helmet may need cleaning from time to time. Remove the pads and use a mild detergent in warm water to hand wash your helmet and straps, leaving it somewhere warm to dry naturally. An airing cupboard or shelf above a radiator is ideal. Do not apply direct heat as this will damage the helmet.
To work properly, a bike helmet must fit right and be worn properly. In order to offer you the best value and fit possible, Giro makes helmets in many sizes, including:
Large = 59 – 63cm / 23.25 – 24.75in.
Medium = 55 – 59cm / 21.75 – 23.25in.
Small = 51 – 55cm / 20 – 21.75in.
Universal Fit Adult = 54 – 61cm / 21.25 – 24in.
Universal Fit Women = 50 – 57cm / 19.75 – 22.5in.
Universal Fit Youth = 50 – 57cm / 19.75 – 22.5in.
Toddler = 48 – 52cm / 18.75 – 20.5in.
Step1: (Sizing your helmet) – In order to determine the size you need, you can measure the circumference of your head. Simply wrap a measuring tape around your head, being sure to locate the tape just above your ears and keeping the tape level front to back. Once you’ve determined the proper size, you can check to make sure the helmet fits correctly. If the helmet you own now doesn’t fit on your head with just a little room between your head and the headband when the fit system is loose, you should replace it with one that does. You should always wear the helmet positioned low enough in the front to protect your forehead, but not so low that it hinders your vision. Once you’ve got a helmet that is the right size, and positioned it properly, you can adjust the fit as follows:
Step 2: (Adjusting the straps) – Open the Tri Loc™ adjusters on the straps. Put the helmet on and slide the straps through the adjusters until they are located comfortably under your ears, making sure there is no slack in any of the straps. Close and lock the Tri Loc adjusters. The front and rear straps should now join at a point slightly below your ears.
Step 3: (Adjusting the chinstraps and buckle) – Fasten the chinstrap buckle and tighten the straps until the helmet fits snugly. How snugly? You should be able to open your mouth wide enough to eat. Make sure the chinstrap is well back against the throat, NOT on the point of the chin. Straps worn on the point of the chin increase the chance of a helmet coming off in an accident. Make sure the loose ends of the strap pass through the rubber O-ring near the buckle. If it does not, the strap may slide loose and the helmet can come off accidentally. Always wear the helmet with the chinstrap buckle fastened and the strap pulled tight.
Step 4: (Adjusting the fit pads) – The helmet fits correctly when it is held firmly but comfortably in place by the interior fit pads and the fit system (Roc Loc® or Acu Loc™). The fit pads inside the helmet are held in place by hook and loop fasteners. You can use any combination of the different thickness pads provided with the helmet until the helmet fits firmly and comfortably on your head.
Step 5: (Adjusting the tension of the fit and stabilizing system) – Your helmet may come with either of Giro’s patented Roc Loc® or Acu Loc™ fit and stabilizing systems. These systems attach to the helmet liner with either hook and loop fasteners or by snap-fit anchors. The systems are fully adjustable and they enhance the fit and stability of your helmet, but they are not a replacement for your helmets straps.
To adjust the fit and stability system while the helmet is on your head, push the buttons on the back toward each other to tighten the fit, and away from each other to loosen the fit. You can adjust the fit even more on systems that use hook and loop fasteners (Roc Loc Mini, Roc Loc 2 or older Roc Loc 3 models) by removing the helmet from your head, detaching the headband from the hook and loop fasteners, then moving the headband towards the front of the helmet to tighten the fit, or toward the back of the helmet to loosen the fit. On systems that use the snap-fit anchors (newer Roc Loc 3/4/5 models), you can adjust the fit by removing the helmet from your head, unsnapping the headband from the liner and moving the arms forward to tighten the fit or backward to loosen the fit. Roc Loc 4/5 and Acu Loc equipped helmets do not offer this adjustment. For safety reasons, we recommend that you do not attempt to adjust the systems while you are riding.
Step 6: (Adjusting the height of the fit and stabilizing system) – In addition to tension adjustment, Roc Loc 4, Roc Loc 5 and Roc Loc Air systems allow you to adjust the height of the system for optimum comfort. To adjust the height, remove the helmet from your head and then slide the Roc Loc arms up or down. Experiment until you get a fit that is most comfortable.
Step 7:(Checking the fit) – Once you think the proper fit has been achieved, grab the helmet with both hands and twist it to the left and to the right. If the helmet fits properly, the skin on the forehead will move as the helmet moves. If it does not, the helmet is too loose. Also, grab the helmet with both hands and try to remove it by rolling the helmet forward and backward as far as you can. Make a serious effort. THIS IS IMPORTANT. If you can roll it off the head completely in either direction, roll it forward so far that it blocks vision, or backward far enough to expose the forehead, it doesn’t fit correctly. If you cannot adjust the helmet to fit properly according to these instructions, DO NOT USE THIS HELMET. Replace it with a different size or model. Once you are satisfied that the helmet fits correctly and that all straps are properly adjusted and tightened, take a short test ride. Pay attention to overall comfort and helmet stability while riding. Make any minor adjustments to the fit pads, straps and stability systems to improve comfort or stability.
Helmets don’t last forever. If the helmet is visibly damaged (cracked outer shell, crushed or cracked foam liner or any other damage) don’t use it. Some or all of the helmet’s protective capacity is used up when impacted, and the damage to a helmet is not always visible.
Even if your helmet suffers a knock that shows no visible damage it is advisable to change the helmet so that you have maximum protection in the event of a further accident.
