Chain suck

I am currently researching which MTB to buy and have come across the term &quot;chain suck&quot; frequently.<br /><br />What does it mean ?<br /><br />Leon

 

It's when your chain snags the teeth of a chainring, and 'sucks' in between the cranks and the frame, eventually locking-up the pedals.<br /><br />This site has more info than you'd probably ever need to know: http://www.fagan.co.za/Bikes/Csuck/<br />

 

Thanks Rek<br /><br />A very comprehensive article indeed.<br />The article mention that it sometimes happens with new bikes.<br />Any brands that are specific culprits ?<br /><br /><br />Leon
