Having experienced catastrophic failure of the drive side crankarm of an Dura-Ace SRM powermeter, you would think that the odds of it happening again would be slim, right?... Wrong!

While lubing up my chain before heading out for intervals on Saturday, I noticed what looked like a scratch on my 6-month old Dura-Ace Wireless SRM. Upon further inspection, it became obvious that the scratch was infact a CRACK. *Insert expletives*...

Not what I wanted to see!... But happy to catch it early.

Looks like I'll be overnighting the SRM back to SRM HQ in Colorado for a warranty replacement. What baffles me is how I have managed to break TWO SRM's... I googled around and haven't found info on anyone else breaking them. One cracked FSA SRM, but that's it. Bizarre!
