4 zip ties

the profile design rm-p with an Xlab gorilla XT cage works well for me (ISM prologue saddle)

Like 6 zip ties. I zip tie it to the seat post so it’s at a good angle and not straight back. Then zip ties to the rails. Let’s see if this picture works..

Guess picture didn’t work from my phone. I’ll try to post later.

Tririg has a post on how to drill a hole in the back of the seat and attach via zip ties. I believe Nick set up Andy Potts with this configuration, but I cannot seem to find the link.

PM if you want me to shoot you a pic from my setup. It took all of 5 minutes and was enough for me to retire my xlab BTS setup (I still use their gorilla cage to avoid bottle launch) .

Thanks....found this on tririg. sent you a pm
