I use my Rock Lobster Ti for touring and commuting. I fit Schwalbe Marathon 25x1.5 for touring, and Specialized All Conditions Pro 26x1 for commuting. It had no rack mounts so I fitted a Tubus Q/R adapter to provide the bottom mount (it also increases heel clearance)
and for the upper mount a Tubus seat stay clip
(they are a cut above standard p-clips, and are very secure)
and for a rack I fitted a Tubus Cosmo
which also increases heel clearance because of the lower, more rearward rail.
I added two extra p-clips (regular cheap ones) for the rear seat stay mudguard mount)
I swapped the Rock Shox SID SL forks for Kona P2 triple butted rigid forks, these have mudguard eyes.
The result is very successful, very stable and comfy. I may get a low-rider rack and bags for future tours.
