Annoying chain drop - why oh why...??

I have a problem with my chain constantly dropping out after I've taken a large drop or jump. I ride a Carrera Ltd Vengence Ultimate hardtail, which in all other respects has been totally solid for the last 6 months.
The chain will fall off at the front and I've tried everything to make sure that my derauillers are set up properly - which they seem to be (ie. they don't over-shoot at either the high or low range). I don't have any problems shifting gears, no weird click-click noises - nothing.
Just a stupid chain constantly dropping out....
Any ideas?
Thanks in advance

does the chain have enough slack so you can remove another link?Whenever I see an adult on a bicycle, I believe in the future of the human race.

Thanks cee.
I probably could take out a link. Will that screw up the setup of my derailleurs if I take out a link (derailleur setup is my bike maintenace nemisis....!)?0 -
Does the chain fall off to the outside or inside?0

If the chain is too long (and every Carrera I have seen it is - the daughters BF we took 2 complete links out of his Vulcan's to get it right) then removing a link will not mean any re-indexing of the derailleur.

if you have the slack, take a link out.
You shouldn't need to touch the mech setup, except potentially the b-limit screw....when the chain shortens and the mech sits more forward closer to the cassette, then you may have to adjust it back...
but as far a limit screws and cable tension goes...this should be all ok.Whenever I see an adult on a bicycle, I believe in the future of the human race.

The front mech is supposed to keep the chain on the correct ring at the front but if it's falling off to the inside it could be a combination of too much chain and a poorly-adjusted mech.
The rule of thumb for the correct chain length is to route the chain around the big-big sprockets - not including the mech - and add two links. I prefer to include the mech and adjust the chain length so that the mech is comfortably fully extended in the big-big combination. You may also want to look at a chain tensioner or a shorter cage mech if you run less than three rings on the front.
As above, the chain length will have no effect on the indexing.0 -
Great, thanks guys.
Chain breaker at the ready...
I'll let you know how I get on after the epic that we've planned for this weekend.
Thanks.0
