Anyone ever used one of these??? My tupperwear is not letting me tie down the front like I would like to...I have installed a wheel chock in the back of my truck..Is it necessary to have to compress the front forks??? The back is no problem to tie down.I thought of using the front forks(middle..just above the fork seals). Then the forks would not be compressed. Sorry to ask...Just wouldnt want my new bike to fall out of my truck...
