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.
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 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.
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 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
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.
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.
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.
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.
A little tricky to install but totally possible. You must connect the middle piece (at the back of the head before connecting the side pieces. To connect that back piece you must turn it 90 degrees and really press hard to get the tiny plastic rectangle through the slot. You then turn it back to normal and the rest is very intuitive and easy.
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??
