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 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.
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.
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.
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.
If your Roc Loc breaks like mine did - use cable ties until you get one of these. Snaps right in. Installation requires undoing the chin strap from one side so that you can thread it through the Roc Loc.
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.
