Hey,
I have a 2010 stumpjumper fsr comp and i am getting a lot of chain slap, but no chain coming off the chain ring. what economical, light and aesthetically pleasing solution do your recommend? I don't like those lizards skins, etc.

Suggest you try to shorten your chain. Go one link at a time. My stock stumpy chain was too long.

Some sort of rubberized, neoprene, or whatever chainstay protecter helps alot. Not a bad idea to put one on your seatstay as well if you go bigger than regular XC riding.

Chain probably too long as others have said, but you will always get some chain slap. That is until they brought out the dangler, but not sure it's available aftermarket yet.
The new XTR rear mech with the built in clutch is a revelation, it stops any chain slap and makes riding a pleasure. Very expensive way to stop chain slap though.

i've been using the fuzzy side of velcro for the last 4-5yrs. doesn't hold moisture like you would think and it is pretty damn quiet. Plus you can cut it to shape. Saw it an article on Sam Hill's Iron Horse Sunday. Apparently he hates a noisy bike. so his wrench came up with it.

its a good idea but it holds dirt and stays wet. I'm looking for something different

Most of the metallic sound with chain slap is the chain bouncing around in the fd. Not much you can do to quiet that. I've gone with a 2X front and bash, a mid-cage rd and shorter chain and I still get the metallic sound on my '10 FSR.

I made one out of a hose you can buy at home depot. Only cost like $3 for a foot of hose. Seems to work good enough for me. It's not silent, but waaaay better.

Get your LBS to order a Dangler from Specialized.

Just tell them that a new bike was dropped and the stock Dangler on it broke.

Then, even though they don't technically sell them, they'll sell you one.

Doesn't always work out, depending on the trail incline, speed, etc., but I make sure I use my big chain ring whenever possible. It reduces chain-slap due to increasing the amount of chain wrapped around the larger chain ring. Hard to do on steep, technical stuff, but good when you can.

Assuming that you have checked your chain length I would go with the old default chainstay protector which is an old inner tube wrapped around the chainstay. You can make it as thick or as thin as you like.

A bit puzzled about the "asthetics" bit. It is a MTB we are talking about right? It is currently covered in all sorts of **** as it has been used. Right?

Innovative and cheap but looks like hell :D. 'Sides, he already has one the came on the bike and it looks sexy, like this. I also have a couple of Lizard Skins on other stays to protect from various scuffage and chain noise.

I went with a MRP LRP with tensioner due to this same concern on my 10 FSR Comp, took a few links out of a new chain I installed as well and it got so much quieter.

I agree. The one that comes with the bike is very sexy. My bike didn't come with one, and i wanted one that didn't keep moisture.
