i cant tuck to save my life but i've been trying what gaz m said and getting further from the wall and gapping into it.imagine this (this'll seem random but i am a geordie).you are on a clock face, front wheel on the 12 back on the 6.that was my usual position for a sidehop (perfectly parallel sp to the wall) if found that this doesnt work good at all imo. if i set up so my front wheel would be between 10 and 11 and my back wheel between 4 and 5, i find this works and has some effect on making you tuck. the further "round the clock" you go the more you end up tucking. are you high sidehoppers setting up parallel or back wheel further away than your front? craig
