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.

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 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!

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

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.

MY original system had multiple broken points and was beyond usable. This replacement system went on easily and I have a fully usable helmet again. Definitely better than buying a new helmet! Timely Shipping and Customer service at BikeWorks 1

The retention system on my Giro helmet broke. I searched high and wide for this replacement part. (Even the manufacturer.). No one seemed to carry small replacement parts such as a helmet retention system. But Western Bike Works had the part, provided excellent customer service, and quick turn around. Now I will always search Western Bike Works first for parts. Thank You. Richard Sertich

I'm glad a local shop had the product in their online store and had it delivered the next day to their brick and mortar store. Product was easy to install. Took pictures of old one to make sure I installed the same way.

The design of the Giro Roc Loc 5 Retention System is poor. It does not take much for the back area to break apart and require replacement. Very poor design especially since it comes installed on $250 plus dollar helments. I would think Giro could get this right and design a retention system with more durability.

This came and was identical to the one that came with my helmet. Took a little work to get the height adjustment tab to go where it was supposed to. Price was so good that I bought 2.

Unfortunately, I purchased this with the intention of upgrading the Loc 4 with this on a Atmos helmet. They are not designed to upgrade the retention system, only replace an existing Loc 5 restraint. Otherwise, the product is as advertised.

Too hard to install

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
rating

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.
