Perfect Fit

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.

original one cracked...this is the replacement
by cheah

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.

Too hard to install
by BigE

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.

Awesome Replacement Saved Helmet

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.

Effective Repair of a Really Good Helmet

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.

OEM replacement saves me having to purchase a new helmet
by MBC in ABQ

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.

Took a little while to figure out how to install the replacement system. No directions. Found a video which showed how to do it. Would help if Giro included a description or video on their site on how to replace.

Easy installation. Cheap fix for a not too-old helmet. Better than buying a new helmet.

It snaps in easily, however it took a few attempts to get the rear anchor in (rotate 90 deg). After that it is just a matter of re weaving the straps through the new Roc Loc.

Need replacement after 2 years
by Anonymous
Casual Cyclist

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. )

Cheap and easy way to extend the life of the helmet
by Dennis

I love the Giro helmet, but the tiny little plastic pieces in the retention system broke in the duffel bag. I tried gluing them, taping them, yelling at them, all the usual fixes, but nothing lasted for more than one ride. Then I found this. At $20 shipped, it was a little bit bigger portion of the total price of a new helmet than I wanted to spend, but this one still has a few years of life in it, and the fit is perfect. So I ordered it, swapped it out in 2 minutes, and now I have a fully functional helmet again. Now I'm just being more careful with transporting the helmet. Seriously, why is this made with such small pieces as the main link holding the helmet on your head??

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.

Works great, but don't install it on a cold day
by AbqSteve

The other reviewers are correct, turn the tab to 90 degrees, slip it into the slot then rotate it into place.

But I COULD NOT get this to work. It was a cold day, and the plastic was too rigid to move into place.

The next day I dipped the part into very hot water, bent the groove a little open, and popped it in with no trouble at all.

Works great, helmet like new.
