There's an idea worth considering. My 24t granny is steel. When you think about it, neither the granny nor the Really Big Cog see a lot of use, so maybe an aluminum 34 would do.
I see a lot of people wearing out middle rings because they're over- geared & don't use the big one. My Atlantis came with a Riv standard Sugino 24-36-46. The middle & big wore out together at around 20-25k miles of mostly dry riding. dougP On Aug 11, 3:31 pm, ted <[email protected]> wrote: > I have heard or read that wear is more of a problem with fewer teeth > and that that was why chainrings are usually al and cogs are usually > steel.
