No No no there is nothing wrong with the current swing arm, turner sent this out purely for cosmetic reasons, let me explain………..
I posted a thread on mtbr about clearance issues i was having between my cranks and the swing arm, whilst pedalling stood up the drive side cranks arm was slightly clipping the swing arm, turner sent me a new swing arm due to this, however the problem lay with the cranks set not the bike, it was cured by fitting a different chain set in this case.
I advertised the frame for sale with the mark on the chanistay clearly shown(more of a chip off the sticker to be fair ) and the guy who bought it off me was happy.
so now i dont own the frame and i have this brand new swing arm sat at home waiting for me to get back into the country.
Even if i send it back to turner its still going to cost me ?
What do you think?
