FC-RS510 Crankset compatibility I've recently acquired a cyclocross bike (Stevens Prestige) with aforementioned FC-RS510 crankset. I am thinking of exchanging the 50-34 gearing which is currently mounted with a 46-36 set because otherwise my typical commuting speed would be just between the larger and the smaller rings. Since the crankset seems to be a slight cost compromise in an otherwise excellently spec'ed bike, I am contemplating upgrading this part in the process. Can I mount any 11-speed 105 or Ultegra crankset? Or to spend slightly less but still upgrade, could I use 105 or Ultegra chainrings with this crankset? If anyone could point me to the "famous" Shimano compatibility charts and how to read them, this would be much appreciated!

Here's the Shimano compatability chart. It's graphical and rather self-explanatory though I'm critical that it can sometimes be confusing and that it doesn't incorporate enough generations of parts. In other words one may want to check compatability of a 2015 front derailleur with a 2019 front crank, however, the newest chart with the new crankset has dropped the older front mech off the list. Obviously the new crankset won't be listed when one looks at a previous year's chart that includes the older derailleur. So check it out and see for yourself.

It appears Ultegra or 105 11 speed chainrings would work on the RS510 crank as they're all 4 arm spiders with 110 b.c.d.:s.
