This intrigues me. I'm getting frustrated with the complexity of my triple, and essentially my big ring is my ring guard. I got lost in the technical jargon though. Could you please explain things to a dummy (because you would be. Grin.)? I currently have the Sugino XD2 Crank, Triple 46x36x24. and would love to drop the 46 and have someone a bit larger than the 36 for my big ring, plus a real ring guard.
Using a 24/36/46 triple is simplicity itself. For riding on level to slighly uphill terrain, stay on the 46. When you run out of gears and need to downshift (i.e., when you are on the next to largest rear sprocket and need something still lower) shift to the 36. You may need to simultaneously upshift one or perhaps 2 in back if the gear you get is too low, or you could just wait a few seconds to let inertia have its way. About the only time you'll need to think about the 24 is on grades over 10%. At that point, go to the granny, and possibly if the gear is too low upshift one or perhaps 2 in back to get to a proper gear. There's nothing at all complex about that.
Some notes on the 24: use it with the 3 or at most 4 largest sprockets. Anything beyond that and you're overlapping with the range of the 36 and unless you can see there's even steeper terrain looming ahead (making it desirable to stay on the granny) shift to the 36 and downshift as necessary in back to get to the proper gear. You don't want to ride on the 24 any more than you need to, because wear is much greater on the smaller chain ring than on the larger.
Likewise, if you are on the 36 and you find you are in any of the 3 smallest sprockets in back, upshift to the 46 and downshift one or two in back to get back to the right gear.
