Here's two 99bis rings on a 93 crank:


Jon Vara's 93 triplizer rings are top quality and affordable, but if anyone's crazy enough to want to make one like mine, I can explain the steps. Actually I'm pretty sure I've written it up before on BF, so apologies for the repeat.

A triplized 93 is not better than a 99 in any way that matters. I think it's actually a less-elegant solution because of all the extra bolts needed. This is just for crazy people who really want lower gears on a "racing" bike that just has to have a 93 for some sentimental reason.
