I bent both of mine last year because the wheel nuts were not tightened enough during a standing start and Planet X were completely useless in aiding me, but someone with the PX frame told me that I could buy a particular set of bolts from an online hardware store which I did to a T... they were the wrong size and did not fit.
Luckily however I brought the correct type which I have in front of me now. You are after **M4 40mm **they are cheap - about £1 posted however they will not have the special PX bolt heads designed for twisting easily by hand but a bit if DIY epoxy or similar will work if you feel the need.
