Anyone used one of these? 

STFU Bike

They're ugly as hell, but the footage looks pretty convincing.  Less noise, less dropped chains, less frame damage, no real drawback aside from looks.

As someone who only rides downhill, all you need is the top chain guide to not drop a chain.  The under-guide-wheel thingy is useless.

The STFU thing will be good for bikes whose kinematics has their chain slapping the stay.

I can't remember the last time I dropped a chain or even thought about my chain since NW chainrings and clutch derailleurs so buying something like this wouldn't occur to me.

This ^^ I think I went a year without dropping the chain and then I realized it dropped cuz I had inadvertantly turned off the clutch.

But maybe chains might drop in more extreme apps ??

Haven't used one

They're ugly as hell

yes - prohibitively so

but the footage looks pretty convincing.

although if you never showed me my chain doing that, I wouldn't know it was doing that and it doesn't actually bother me.

Less noise

Most bikes are pretty quiet these days with all kinds of rubber mats on the chainstay to limit noise

, less dropped chains,

as mentioned, doesn't really happen much

less frame damage,

They are too well protected these days. Who gets serious frame damage from chain slap these days.

no real drawback aside from looks.

That is one big drawback - it looks really unelegant.

It seems to me that they are trying to solve a problem that is only a problem on a small fraction of modern day bikes. If all I did was ride WBP all year round, I might consider it but for trail riding it is way overkill IMO.

Yeah these responses basically confirm my thoughts. Cool in theory but mostly useless for most people.

I'm still waiting for front deraileurs to become a hot item.

its a good thing we got all them chi-chi chunks of designer rubber caressing the drive area, the clutch der & N/W cuz we don't have inner tubes to wrap around the chainstay anymore

We use hunks of old Maxxis tires as chain stay Protectors now. Those tires are wiggly enough to go straight on curved chainstays.

Some Maxxis come pre-curved just for that purpose

I have it, it's great. On my old bike with a pretty worn drivetrain it reduces the slap a bit, not a huge difference. On my new bike it reduces 99.9% of the slap, bikes very quiet.

But, if I wasn't riding bike park a lot of the time I probably wouldn't bother, as it's more noticeable when you're doing fast dh runs. 

If you don't think you need it, like the current amount of slap on your bike is fine, you're probably right. If the chain slapping around drives you crazy, go for it.
