Swapping groupsets over...used chain v new crankset
i have just bought a new bike with ultegra 6700 and am thinking of swapping the groupset with the dura ace groupset on my other bike. The other bike has a BB30 FSA SL-K chainset which I will leave on the bike and buy a new dura ace chainset and BB for the new bike which I will be fitting the duraace groupset...still with me?
My question is the used duraace chain likely to cause excessive wear on the new duraace chainset due to mixing new and old? The chain has probably seen about 800 miles of action in good weather only.
The question is relevant on the other bike also but this will be new chain and used chainset?
the reason for swapping is the new bike has a lighter frame so want to get the bike down to about 6.4kg

it should be ok, 800 miles in good conditions shouldnt have caused much wear, go out on a ride and put the chain under some proper load in all the gears, if it slips on the sprocket then stick a new chain on, if it runs ok your good to go.0

Just measure the chain carefully with a steel rule while under tension.
From one edge of a link or pin to the same spot 12 inches along.
Should be 12 inches exactly, 1 sixteenth over and it is too worn.He is not the messiah, he is a very naughty boy !!0 -
Your spending a lot of money, what more is a new chain?0

ha yeah new chain? thats true, though sadly the pot of gold isnt endless and then theres the issue of new chain and old cassette = chain slip which surprisingly happened on a 6 month old allez when a new chain had to be installed. surprisingly the cassette had to be changed though maybe too much cross chaining0
