clang noise when derailleur hits chain stay

[baobab]

Hello. I'm a newbie and I just bought a jamis trail x3. Is it normal for the rear derailleur to hit the chain stay producing a clanging noise everytime the rear wheel hit a pothole, for example, or dropping from a stair step? Any solution to get rid of this noise?
Many thanks.

lagyan mo ng goma yung chain stay mo also works as a chain stay protector para hindi masira yung pintura pag tumama yung chain mo sa chain stay.

bro my frame is a jamis x2 naman almost parehas lang yung frame natin decals lang pinagkaiba ata..

sakin naman yung chain mismo natama minsan sa chainstay pag nalulubak what i did is bumili ako ng chain stay protector meron 100 php lang sa mga lbs.

kapag may chainstay na.. yung tunog ng pagdali ng chain sa FD...

tagal ko rin hinanap source ng "klang" na 'yan. May chainstay protector na, ganun pa rin. di rin naman umaabot ang RD sa chainstay. Also, malabo din na sa FD kasi ang liit ng point of contact nila (not to mention yung distance ng side / wall ng chain sa FD )to make that sound. Then i realized that its the chain hittng the chain ring. Lalo na pag naga middle ring ako. Will try shortening the chain to make it tighter. Is there a rule of thumb regarding sa length ng chain? tnx

are you sure it's the RD that's hitting the chainstay? or is it just the chain, as the others have suggested?

if it's the latter, you'll have to rename your thread title, kasi misleading.

Ser yung sa akin ay yung RD mismo ang tumatama sa dulo ng chainstay pag nalulubak. normal lang ba to? may dapat ba akong higpitan, iadjust o ayusin? Please see image. Thanks sa lahat ng nagreply

i tried to compare yung pic mo sa bike ko same tayo ng frame deore 2010 shadow type rd ko pero pansin ko parang masyadong maliit yung gap ng rd mo from your chainstay yung akin kasi almost 3.5in yung gap...

mukang meron kelangan iadjust better pacheck mo sa naginstall para sure

im not a real bike guru ha, pero i think masyadong mataas yung arm ng RD mo. try loosening it then rotate mo yung buong RD ng clockwise (the word deore 2010 on your RD will be read from top to bottom).

anymore comments? sa bike ko kasi ganun ang setup ko eh and it works naman.

i think tama yung point ng kanyang title. sa pic kasi, mukhang papalo talaga yung RD sa chainstay

that's why i asked. and the photo was posted after my comment.

Sir,
Try to adjust the B-tension screw. It will move your RD/pulley away from the cogs. And may give you enough clearance on the chainstay. Also this will give more tension on the RD spring which could lessen the "clang". =)

Problem solved!
I adjusted the b-tension screw as suggested by ezrydre.
Many thanks to all who replied.
