Numbersdenote number of teeth on smallest cog i.e. 11-32 has smallest cog with 11 teeth, and largest with 32 teeth. 11-32 gives you larger range of transmission ratios while 12-25 gives you smoother steps between the speeds. When calculating which one to choose also take into account number of teeth you have in front, and the kind of terrain
Currentlybig-big (36-30) looks like this: Yeah probably gonna need to be a bit longer your rear mech looks stretched enough that the extra teeth will be to much. I would buy a new chain. You'd be surprised how few chains need to be lenghtened going from a 32 to a 34, but 30 to 34 is a big gap, likely gonna need 2 or so extra links.
Butbeing tempted by spending a little more on a Giant Contend 1 which is available but not keen on the set - Allez is Claris 11-32 and Contend is Sora 11-34. Looking at the specs I get this: Claris - -21-24-28-32. Sora - 11-13-15-17-20-23-26-30-34. So yes, I get an additional gear but the gaps for both are very close or the same
Ihad an 11-32 before and I found the difference between successive gears was too big and I was always in too high or too low a gear to be really efficient. I already had a triple, and
Notethat if we let V 1 = 7 and V 2 = 5 we would still have a difference of 33.33% because we are calculating a difference between two numbers and not a change from one number to another, percentage change..

If you run a 52/39 and an 11-28 on the road, then a 50/34, 11-34 should be plenty low enough for youassuming your gravel is of the fairly smooth/hardpack varity. I run a 50/34 and 11-28 on the road, and was running a 50/34, 11-32 on my gravel bike, but just switched to an 11-34 (still haven't
