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.

Does NOT fit Montaro
by Anonymous
Cycling Enthusiast

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.

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.

OEM replacement saves me having to purchase a new helmet
by MBC in ABQ
Cycling Enthusiast
Albuquerque, NM

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.

Restored my Giro Aeon to 100%

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.

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.

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.

Need replacement after 2 years
by Anonymous
Casual Cyclist
Freiburg, Germany

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.

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.

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.
