>>1913531>Front tire should be the same as the rear or bigger. Not the other way around.>>1913551>Because of that front tire should be wide and grippy and rear tire can be narrower and better rolling.This is MTB logic. Begone.
Conti even sells a tire set (force/attack) which are 23 front 25 rear.
>>1913519If you want to read the shill explanation for why it makes sense then go and read their product info.
They will say that 23 is more aero and that it matters more for it to be aero and 25 is more durable and that it matters more for it to be more durable.
I have ridden bigger rear combos myself quite a bit, usually out of circumstance with what i have on hand not by design.
Imo it's not about that, there are 2 things for you to consider. 28 rear will give you more traction which matters if you ride steep climbs out of the saddle in the wet or offroad (that's when you will demonstrably reach the limit of traction in the rear without it mattering so much in the front). Ie a serious roadie in the hills will have to limit their climbing by when the tire actually slips.
Other than that it's about how the tire feels. Not whether it's fast but whether it feels fast. And not whether it's 'comfortable' but whether that is something you even enjoy or not. Personally sometimes i've found going to 28s or 30s or 32s on certain road bikes to dull out the ride in a way which I do not enjoy. The narrow tires ride 'fun' and feel faster for fun fast riding.
Lastly it looks cool.
It's actually an insignificant choice though. So I hope you're looking for autistic discussion rather than explicit advice or to find the 'right' answer.
