Does anyone know what might cause a chain to slip to another gear when coming down from a jump or a hop. It is anoying because I have no pedaling power until the chain goes back where it should be. Is this a hardware problem, or just something that takes practice to avoid? Thanks

When you figure it out, let me know.
I only have that problem after long rough periods of down hill,
I don't have that problem with my soft tail though.

You can avoid it sometimes by keeping the chain as taught as possible,that is by selecting the gear ratio's between chain ring and cluster to keep the chain tight as the frame flexes.If you look at some downhill bikes they have special chain tensioners to prevent this problem.

I looked into the tensioners, and all that I saw only work if you want to convert your bike to a one speed. The tensioners that you've seen, are they for multi-gear bikes?

To be honest i can't recall if they were multispeed or not,i'll keep an eye out on the tracks this week and see if i can spot someone and inquire for you.

Also make sure that your derailluers are adjusted...can have an effect on dropping chains. If your still wanting a chain guide,you can get multi-ring guides but i dont think you will be able to keep a third chain ring if you have one. Here are 3 examples. Truvativ make the shift guide. http://www.sram.com/en/truvativ/gui...tguide/team.php Blackspire have the Dewlie series.. http://www.blackspire.com/chain-guides/dewlie If your prepared to pay a little more, the e-Thirteen DRS would be the way to go. http://www.e13components.com/product_drs.html Depending on what type of bike you have, you will probably be looking at the "BB" (Bottom Bracket) type. This bolts, as BB suggests, onto the bottom bracket. The other type of guide is called ISCG and consists of series of tabs which means the guide is bolted staight to the frame meaning it is stronger, bot mainly Downhill Bikes have this feature. Good Luck mate!
