I’m about to buy a giant trinity comp that comes stock with shimano ultegra 53/39 crank. I want to put a 54 on it and keep the 39. I understand that the shifting performance will diminish. What are my best options here? I’ve found the dura-ace fc-7800 54T chainring but was wondering if this will work/ if there are any other options. Thanks in advance.
Which Ultegra version is on the Trinity?
Can’t find the specific specs…I gather you are asking a or b type?
