Well, no. I realize you may be talking about road bikes, but Shimano's SLX double is 22 teeth on the small ring, as is their SLX triple. So in that one case, the triple does
notprovide a lower gear than its corresponding double. What you actually lose are a few higher gears; you lose the 44tooth ring.
