Well, we really only had one for quite a long time. My understanding is that SRAM wouldn't license XD to Shimano, and since everybody wants a 10 tooth cog these days, they had to do something.Don't you just love all the different standards we have?
You sure about that? That's exactly what Sram does. So does Trek, Specialized, Cannondale, E13, etc, the list goes on. Intentionally making products that only work with their own standards. That's why I won't buy those brands.The old 'too many standards' argument is getting tired. I promise you that engineers don't actually get together and try to dream up new standards just for the sake of adding to the pile of old ones.
Except that by introducing Dub, SRAM rolled two spindle sizes into one standard. Dub is replacing 24mm and 30mm spindles. To me that is more than an incremental improvement. I like GXP better, but if I can get a stiffer/lighter spindle in Dub and have better bearing life than with a 30mm spindle, I don't see the problem.Well, I agree that most companies design things to improve on their previous products. However, the improvements often times, including SRAM Dub, are so incremental that it is pretty clear they are after a few bucks by forcing upgrades. Hey, I get it. Companies need to make money. Just don't pretend that they are doing things in the best interest of the buying public.
But Dub isnt lighter than 24mm. This is from a weight weenie who wanted to use their cranks. Sure, the highest end crank is lighter, but the more affordable options are not such as the stylo. The dub stlyo is acutally 70 grams more than the 24mm gxp. My 9 year old xt was lighter with its outdated 24mm spindle and god forbid chainring bolts. Maybe the bearing life is improved or stiffness, but im not flexing a 24mm spindle on a road or mtb. Bearing life was amazing before press fit. Eh, back to my hole.Except that by introducing Dub, SRAM rolled two spindle sizes into one standard. Dub is replacing 24mm and 30mm spindles. To me that is more than an incremental improvement.

We are talking about marginal gains though. And that is why I say it's a matter of perspective. It's up to you to decide whether that gain is worth your money. But marginal gains are different than change for the sake of change.
