you almost have me sold. i was eyeballing the laidback seat rests too, but since you include them, all the better. i still would like to know how much the hold though. i run a 29er mtb, and find myself having to refill more often than i like. soon i will have to employ my bike as a primary transport. the idea of carrying a liter or two of spare fuel was not pleasing. anyway let me know. i may purchase one.thumbs up on being bulletproof. i like to know that if i wipe out i wont get soaked in fuel.
