bottom line: clinchers for training and club rides ...tubulars for race day.
I can't rationalize the extra expense of tubulars for training and club rides. Just like I can't rationalize using spendy tires on my rollers.
I canīt rationalize any of my expenditures for my bike, nor can people rationalize their expenditure for cars or other commodities,- we buy whar we like and what makes us feel good. 95% of road bikes that are bouht propably will not be used to theri fulle racing potential, but people buy them because itīs fun.
