At last.....my R20's got a straight chainline and a quiet chain tensioner
Just installed a 110mm UN72 BB on my R20 single speed, much better than the 127mm it had. I now have a straight chain line and guess what??...
The chain tensioner must now be happy 'cos it's decided to "SHUT UP" ;)
This SS is a temp project as I've got a new set of 451 rims with a Sachs 3x7 hub waiting to adorn this bike and the SS's 406 wheels will be converted back to a 7 spd into another R20 frame I'm building up. This 2nd bike will possibly have 2 chainrings 58/48 and Vbrakes, so I'm going to be busy.
I will post pics when they're finished....both will be BLACK and named "The Scarab 1 & 2" aptly suggested by LittlePixel.
