I guess the title should say "Will the chainrings shift correctly", not the "Cranks"...



I have an Ultegra 9 speed triple (130/74 BCD) and will be changing out the chainrings for the type of riding I do...

Mostly up hill...

Right now one of my bikes has a 48/36/26 Deore (104/64 BCD) which shifts proper but is getting old and tired...

When descending I do spin out with the 48 x 12 combination...

I was wondering if I can go up to a 50 in the front and still have the proper derailer range with a 26 or 24 small ring...
