Use Ring-O-Star headset adjuster

Anyone have any experiance/thoughts about the USE Atom stem. It comes with something called a Ring-O-Star, which is used instead of a bolt and star nut. The idea is to save weight and reduce damage to steerers (especially carbon ones).

I really like the clean look, light weight, and nad/knee friendly design.

hopeful bump before this is dumped.

Hi, my first post... anyway i had a Dolan with an Atom one piece carbon stem and bars with the ring-o-star setup. It looked quality but I found it couldn't put enough pressure on the headset, which caused a fair amount of play, especially when you ride over any bumps. I thought I had a faulty ring-o-star, so I ordered another one but it was just the same. They look great but for me the play and movement was inexcusable.

If you don't want to use a star nut, you can try a Hope Head Doctor. Have one on a bike now. Seems to be working great. Don't think there are any weight savings though.

Unfortunately with the atom bars you have to use the ringo widget as there's no access from the top. But if you go for a different stem then i'd also recommend the Hope Head Dr.

Yup head doctor great bit of kit

Cheers I was thinking of getting a Hope headset anyway. This stem just caught my eye as it is heavily reduced on CRC as is the USE atom flat bar.

@tedders
I would be putting it on a single speed 29r with rigid forks. So it would need to cope with both sharp bumps, and me throwing my weight around in a vain attempt to climb mountains sans gears. That'l be a no then :)

Cheers for the input, and welcome to the forum.
