Woo. Mine only slip about 5 degrees but it's pretty dang annoying. I have had these FSA Carbon Track Pros since February or so and they are very disappointing. The chainring is very high quality but the crank arms are lackluster and now the system has started to slip. Apparently all FSA does is disassemble them and epoxy/glue them back together, so guess what I'm going to spend my Friday night doing?
I just want to know who else has shared this annoyance and maybe disassembly tips.
No slippage. But my spider is mis-aligned by a couple degrees. I need to take it in to get it either serviced or replaced. Maybe take off your chain ring, clean everything, put a little grease on each bolt thread and put on/tighten them back in a star pattern.
You have the newer track pros and not the vigorelli, right?
