Hi.

i need to replace front inner tube, searching a lo i find TOO MUCH TUBES TYPES!! Normal, Heave Duty, Ultra Heavy Duty, natural rubber, mix rubber, sinthetic rubber, valve type, weight...

Reading a little i found that the NATURAL RUBBER are better than the sinthetic and more expensive, also find that the HEAVY DUTY and ULTRA HEAVY DUTY are ONLY for offroad use (because when you are at high speed the inner tube produces some vibration)... so, what kind of inner tube i choose? and what brand are good?

Thanks a lot!
