The last thing a new cyclist needs is something thats a huge hassle and tubulars are just that. Gluing and mounting tires can be a very messy affair and carrying a spare tire around with you takes up quite a bit more room then simply carrying around a spare inner tube for clinchers. You could carry a can of sealant around instead of a spare tire but if the punture is big enough the sealant will not work. My suggestion is to ditch the tubulars before you open a big can of headaches. Again there is nothing wrong with tubulars but learning the basics of cycling and your equipment can be overwhelming enough as is.
