Swapping rings on an FSA crank
I have an FSA SLK crank that has a worn top chain ring. It's currently running 53-39 chainrings. Can I install a 52 or 50 tooth ring, or will I have to buy a new crankset to install a ring with different sized teeth?

Is the difference between a 48x11 and 50x11 negligible?

The bolt circle diameter also sets a lower limit on the number of teeth a ring can have. Here's a 38T 130BCD chainring, but the maker notes that the chain will probably contact the crank spider so realistically 39T is as small as you can go.

48 x 11 and 50 x 11 difference being negligible really depends on you and the riding you do on the bike. I'd notice it on the road but not on a limestone trail, for instance.
