Whether to sell the Niner R.I.P. 9 and ride the fully rigid S.I.R. 9 Niner or keep the Niner R.I.P. 9. I'll replace the borrowed images with actual pictures this weekend. The "Steel is Real" SIR is equiped with a Surly Karate Monkey fork. I'm pretty sure "we" have owned four or five Karate Monkey forks throughout the fully rigid ride debate.
