i fancied building a single speed bike
bought a DMR single speed kit which inc a 16t ring
running a 32t front ring
QR drop outs.
install as per instructions with the chain going round the rear ring and over the dmr chain tensioner - i couldnt get the chain tight enough so tried running the chain round the outside of the chain guide - still couldnt get the chain tight enough.
so i bought a 20t rear ring, same situation again (having added a link to the chain)
so i bought a 18t rear ring, now this is the best so far (link removed - so chain in the same length as when i tried the 16t) but still i cant get chain round the rear ring and over the chain guide as it should be.....
what am i doing wrong.... do i need to change the front ring to 30t??
