Am doing my bit for the cycling community by relating a safety problem with Zero Gravity brakes.
Live in Oz and have done an upgrade on the KG 381. Got to keep up appearances, I've got the Look.
Anyway, I got myself a set of Zero Gravity 2007 Titanium brakes mail order from the US. Out here in Australia the retail mark up is such that ordering parts in direct, offers significant value.
Installed the brakes as per instructions. No problems.
Went for the Zero-G maiden voyage, along with a heap of other new light weight go-goodie bits and had to put in a slow, tight turn against a slight rise. I had to hit the anchors suddenly and then I was on my way. Next time I needed to brake, which was at the end of a down hill slope with a road to cross, up ahead. Time to slow down but not to be. My front brakes didn't provide any stopping power ...
Reason? One of the brake pads had slipped out of the brake shoe, when the wheels rolled backward with the brakes applied.
Fast forward to a late night call that day to Ciamillo Components Inc in Atlanta for a "please explain". Turns out the problem is known to the helpful fella at Technical Support and he says, "No worries, I'll send you a replacement set of shoes and pads".
The explanation was that Zero G / Ciamillo were contracting out machining of various parts and quality control went adrift. The shoes in my case were out of tolerance by tenths of millimetre. So, when you've got a Campag design that doesn't use a retaining screw to keep the pads in place then tight tolerance is critical.
I've got the new units. They work a treat ...
I thought I'd put a post in here because this is the most obvious place another cyclist would expect to find comment like this. I went searching when the problem arose for me and I couldn't drag up a skerrick of info. I would have thought that a voluntary recall would have been posted (if it has, then I didn't find it).
So, if you're keen on the Zero G's great. They're great bits of gear. Just make sure your brake pads are tight in the shoes and test them before you build up a head of steam rolling down hill. If they fall out like mine did, then get yourself a replacement set from the manufacturer.
Keep on riding and ride safe.
