Too hard to install
by BigE
Cycling Enthusiast
Bradenton, FL

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.

Exact hard to find OEM part that I needed to rescue my otherwise good helmet. Fit perfectly.

I didn't know this was replaceable... I was happy to find an inexpensive replacement part when my 3-year old retention device on my perfectly good helmet was broken.

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.

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.

Good product. Easy install.

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.

Fit EXACTLY as it should
by rpeastman

The old version broke. The replacement fit exactly as it should have - slipped directly into the existing sockets after removing the old broken s Roc-Loc pieces. Worked as it was designed. Actually, a fair price as well.

Perfect replacement for Giro Atmos
by Anonymous
Daily Commuter

Plastic part snapped on the helmet and I looked to see if I could get the replacement part instead of shelling out $100 for a new helmet.

Made sure it was the same locking system (there are multiple types for Giro helmets so make sure) and removed and installed with little to no drama.

The hardest part was snapping the top part back into the helmet. I had to twist and push the tab in. Everything else was just carefully routing the straps through.

Does not fit an Air Attack

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.

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.

Cheaper to replace than buying a new helment
by JR Bandy
Competitive Racer

1 of 2 customers found this review helpful.

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.
