hi all
just replaced my chain from the original 1 a kmc x9?
have done about 400 miles mostly fireroads
put a shimano hg53 on done about 20 miles friday.
and it snapped yest. morn about 2 miles into my ride whilst i was changing down a gear on a very slight slope?
i have got a habit of changing both front cogs and rear at the same time!!
do i just take out snapped link and put in a power link or is a new chain required?
i put the new chain on by running it over both large cogs and adding 2 links
cheers paul
