rider=160-165 lbs
gear=20-25 lbs

With my existing bike frame, I run into tire clearance issues when going above 25 mm front and 28 mm rear. I would like to think that 25 front and 28 rear would be enough for most paved roads. what do you think? How will that setup fare in south america or south asia? do they have a lot of gravel or cobbles?
