Gearing is a very personal call.Did you lose some top end? I’m not sure if I would benefit from any re-gearing or not.
Going up in the front will reduce your RPM at WOT for a given scenario all else being equal. For example, wide open on your favorite stretch of road in 4th gear if you go up one in the front, you will go faster IF the engine still has some power left to utilize that taller gearing. The downside of that move is that your acceleration to reach that speed will decrease. The reverse is true. Going down a tooth up front will slow your top speed all else being equal because your RPM will hit the limiter (assuming the grade and load are suitable), but you will get to that speed faster.
Go ride your bicycle for a while and play with the front derailleur and this will make sense.
Going up teeth in the rear will produce an opposite effect from the front. Going up in the rear will INCREASE RPM at WOT for a given scenario.
In my situation, I ride hilly terrain with frequent slowing and accelerating.
I want to be able to hit the limiter in 4th on certain sections, and as of now I cannot due to being over-geared, geared too tall, too few teeth in the rear for the increase in the front.The max power band with my engine setup ramps up from 8K to redline RPM. If I can't get there, I am overgeared.
36T should do it, if not I will try 37T.
I don't care about losing some mph top speed.
I am still in danger of getting a ticket for speeding when I ride 😀
