PEC DEC quic connect (most up to date instal) 

Make your pec dec X bag a quick connect with a stick and two 6” voile straps!
The bag of parts you assume 100% liability in assembling into a rack thing :: works 100% fantastic on the front, and good enough on the rear if you have braze ons in the middle of your seat stays as on a riv or crust. For a rear bag support, i would recommend the nitto R-10. It works better than the “diving board” supports out there that tend to bend and become more bendy with time.
