I have a 48/36/26 Deore crankset and I've never once used the large chainring. I'm planning to move the crankset over to a Surly Troll or Ogre so I see even less chance of my using the 48t ring. I would like to replace it with the SLX bash guard but one sight had two reviewers saying it wouldn't even work on their SLX cranksets. The BCD is correct and from my research it sounds like I might need longer bolts. If so, what would these bolts be and where would I get them? I would like to buy a torque wrench and do this myself but will take it to the LBS if it's a complicated process.
