My new favorite (read most recent) set up is hybrid gearing: 48/44 in front with a front der; 18t Sturmey AW and Alfine tensioner in back.It'll be something else next year!D.On Wed, Apr 10, 2013 at 7:46 AM, bikealfa <mtwils@...> wrote:
None of my IGH bikes have chain tensioners. On all but one* the rear wheel moves in the dropout to adjust the chain tension.
I know this has the disadvantage that the rear wheel needs to be moved periodically to keep the chain from falling off, but it has the advantage that the chain will not skip even with worn sprockets, and the additional advantage of simplicity.
My not-so-humble opinion is that if I am going to use a chain tensioner, it might as well move sideways and also be a shift mechanism.
I would be happy to read the pros of chain tensioners and IGH.
