GiroRoc Loc 5 Retention System(Return to Product Page)

At first I thought it difficult to install considering the first one cracked and I thought this piece too fragile to really man handle. Mine cracked on the thinnest part of the lateral side of the piece. There's a few online reviews of people complaining this is hard to install as well. Not the case however. You have to, with your thumb, push the male piece out far enough so it will fit back in the female end. It won't break, the plastic is flexible enough. The whole piece though, unlike the original, moves up and down far more easier and freely once the replacement is attached. I actually didn't know it did that......but it most certainly does now. Not a bad thing however. All of this will make sense should you try what I'm saying.

This is the exact part that comes with the Giro helmet. I give it only three stars because it was impossible to install like original. The sides have round tabs that snap into the helmet easily, but the back has a rectangular tab that twist horizontally into a plastic insert on the helmet. Since the plastic insert was in the helmet I could not twist the retention system into it, and I am almost certain that during manufacturing this plastic insert was put into the retention system first and then on the helmet.

However, you can still use this Replacement Roc Loc 5 retention system by cutting the rectangular tab off and gluing the retention system to the plastic insert. This is what I did, and it works just fine.

Only fits Giro. Better then buying a new helmet.

Great price if this actually fits your model of Giro helmet. Unfortunately it does not fit my Montaro. I should have paid more attention before ordering but the description made it sound like it fit all Giro helmets. The Montaro uses a one piece retention system that goes all the way around the forehead area, where this is just a rear section.

I overcame my fear screwing up the repair after watching a couple of YouTube videos on replacing the Roc Loc 5 retention system on my Giro Foray bargain helmet. I've had it for a couple of years - the helmet - and a piece of the original retention system broke loose near where the part that connects to the helmet's rear intersects with the part that holds the adjustment wheel and also connects forward left and right. Getting the strap back through the retention system is what freaked me out the most, but I managed it in two tries by exercising patience and with the certainty that I couldn't mess up the helmet worse than it was when the original part broke. I'm very pleased with the result as I like the Foray helmet better than my old Catlike Compact'O.

This product is a perfect replacement part for rehabilitating my helmet. Im back in business.

My favorite helmet is a Giro which uses the Roc Lok 5 retention system. The fit, adjustability and comfort of this helmet was just right, so when the (rather flimsy) retention system side strap broke, I was happy to find its exact replacement. As for fit and function, I give the retention system a five star rating, but because its plastic or nylon parts are not exactly robust, and for how difficult to install, I'll take off one star. The helmet has lasted with almost daily use since June 2014, so 2 12 years of use before the retention strap failed is pretty good, but not great. All plastic andor nylon is subject to UV decay, so the expense of replacement is not a big deal.

Installation is a bit tricky. Before you remove the old system, memorize how it fits, or better yet take a picture with your phone so you won't be frustrated how it goes back together (especially the end of the center strap). The side straps snap into place easily, but the center Y shaped strap takes some fiddling to get it to snap into the receiver which is part of the helmet. I had some small electronic chain-nose pliers which were essential in this process. I spend quite a while trying unsuccessfully to get the pieces to snap together using only my fingers. If you do use some sort of tool, be careful not to force and break anything, as there are two very small tabs that must mesh to secure the center strap. Giro could have made this part of the replacement easier, but it's probably a necessity to make sure this piece doesn't come unsnapped in a crash that necessitates the fit being so tight. Overall it's like getting a new helmet.

My Giro Aeon was breaking down and I asked a repair savvy friend to recommend a new helmet . He suggested I purchase this kit and save the cost of a new helmet . I snapped a few cell phone pics for a reference and took the broken pieces off and installed this kit and laced my straps using my pics for a reference . The whole project took 15 minutes , required no tools and restored my helmet to like new condition.

I took them at their word that it fit newer helmets. It doesn't fit the Air Attack - back it goes. The review is based upon that.

The grey 'case' of the lock broke apart after 2 years of usage aprox. twice a week. For more durability this part should be from fiber plastics or something like this. On the other hand the retention system is very easy to adjust with one hand and comfortable. Looks like no shop offers the spare part in Europe so I came here. My helmet is still in very good condition beside the broken lock and this service will ensure an again satisfied GIRO customer. )

There are no installation directions for this item, and it is next to impossible to install. The product is fine, if you can get it back into the helmet.

This was the the correct replacement part for an old broken one and now I can use my helmet again! Cheaper than buying a new one. Pretty tricky to get on, so I recommend watching a how to video.

Fit beautifully and saved me from having to buy another $250 helmet- they even got rid of the tiny spring that broke on the original that came in my helmet- ratchets better than ever as well as increased comfort!!! Definitely buy!!

So I replaced the retention system in my

Giro helmet with this product. It fit perfectly and was fairly easy to install. Unfortunately, I crashed the helmet a few weeks later. Glad I had the new retention system.

Bad design. Broke 2 wheels in first month and 2 since trying to be careful. LBS says you're supposed to adjust it once and never touch it again. Uh huh. That might work for a pinhead, but not normal people who sometimes wear a hat underneath.

Wasnt even sure this part was able to be replaced and was glad to find it available. It was a little tricky to align the pieces and replace out this part, but overall only took A few moments. Havent had an issue since.

I only used it once, crashed, cracked my helmet but the retainer held the helmet in place.

This system is not the most durable. When mine broke I thought I needed to buy a new helmet. I was so pleasantly surprised that this replacement is available. My helmet is like new again!

Replaced my broken lock system. You offer the least expensive and most timely service for my biking need. No negatives to speak off

As others have noted, this Roc Loc 5 retention system replacement part repaired what had been, up until a plastic tab broke out of the original system near the adjustment wheel, my favorite bike helmet ever. Installation, again as others have noted, would have been problematic without one or two helpful YouTube videos. Well worth the price.
