ryac Posted June 22, 2010 Report Share Posted June 22, 2010 I have a tensioner on my bike. What benefit does that provide when I've seen setups without it? Just assurance to keep the chain tight? I've bent the hanger for it twice now and its pissing me off.. Quote Link to comment Share on other sites More sharing options...

TROYston Posted June 22, 2010 Report Share Posted June 22, 2010 Erm, you can run a bike with-out them, bit i'd personally use a sprung or snail cam type tensioner. Down to you. Quote Link to comment Share on other sites More sharing options...
Alex Dark Posted June 22, 2010 Report Share Posted June 22, 2010 Unless youre incredibly lucky and have perfect chain length and thus tension...you'll need some kind of tensioning device. This can take the form of chain tugs/ cams - where the wheel is moved backwards along the horizontal dropout by either being pulled or pushed Sprung tensioner - Uses a spring to ensure constant tension on the chain.... 74kingz, spoke tensioners or Rohloff are good examples of these. Fixed tensioner - Less commonly used now, but still being made. Simply a captive tensioner that is held in place. DMR STS ( simple tensioner ) is the main one used in trials. If you're bending hangers, then consider using a 74kingz style or spoke tensioner. Both cost little or nothing to make and work brilliantly if executed well.
