I have just ( 2000km ) put a new o'ring chain on , along with new front and rear sprockets in the hope of curing this problem before it rubs right through my frame. Although the stock chain still looks good and has hardly needed any adjustment from new.
However , this has not cured the problem , and the new chain is still rubbing on the downtube. I wrap tape around the tube before every ride to minimise damage , but the chain quickly rubs through it.
Anyone else had this problem , or got any ideas of how to fix it ??

I just checked from my bike that there's about 1 cm from the chain to the down tube, when the bike is in rest. If you have less, check the sprocket.

I did think of changing the swing arm slider - it is not worn through , but maybe the original chain has left enough of a groove for the new chain to simply run in its tracks ?
I also have about 1cm+ between the chain and frame tube when at rest , but is the front sprocket sided - in other words is it possible to put it on the wrong way around ?
The other thing I forgot to mention is that I have fitted a 15T front sprocket instead of the 14T original - i dont suppose that makes any difference?
