Truvativ BB help/instructions
Need some guidance regarding the Truvativ Giga Pipe Team DH ISIS bottom bracket. I've Googled and looked on SRAM's site for instructions/specs ect to no avail...The PDFs SRAM/Truvativ offers are not accessible to this blind OP, and Google has failed me.
From anyone with experience with (or with similar) BBs, are there spacers to adjust the chainline? I'm running an oddball tandem setup (currently a double configuration on a triple crank, sometimes using the inner two mounts and sometimes using the outter two depending on expected ride...long story, don't get wrapped up in this goofy setup). Anyway, looking at possibilities and options to install a FSA triple crankset I have.
Secondly, the above BB is an 128x83/83E, but the current BB on the bike is advertised as 121x82 (not yet verified however). Besides moving the chainline outboard a bit (depending on whether I end up with a triple or double front in later incarnations) should I expect a problem with the 1mm difference in old vs. new BB widths?
[Asked this once before, but never got an opinion]
Any thoughts on the swap, or a link to a good set of descriptions/specs/instructions for the Truvativ Giga Pipe blah blah blah BB would be appreciated.
Third (throwing this question in just to keep it interesting), I currently have a set of tandem FSA Carbon Team Pro ISIS cranks (a triple), if I find a Carbon Team Pro double crankarm, it should be a simple swap of that one arm???
Thanks,
