White Industries VBC Crankset not compatible with Campagnolo...

[jtbadge]

The R30 stuff definitely uses different rings, as the 30mm spindle is larger than the opening at the center of the square taper VBC rings. No idea how they differ otherwise.

Yeah, I think you’re right, I stand corrected. Still begs the question of why one set can shift so well, and the other, well, yeah... Makes me wonder what the VBC was really optimized for?

The whole idea sorta suggests it wasn't "optimized" for any specific configuration at all, right? If it were they'd sell paired rings I'd think.

White Industries are very helpful in general and may just be managing expectations ie it will not shift perfectly.

Square taper vbc works well for me and I am happy to trade some perfection in shifting to get a 46/28 on the front.

Fair enough. My only beef is going back and forth from ring to ring. It is what it is I suppose.

Why go through the R&D and not come out with something that shifts beautifully every time? I can’t wrap my head around charging a premium price for a product that work pretty well most of the time, for some people. I’m not trying to bash WI at all. I love them and their products. I just don’t get putting a product out to market that isn’t even optimized for 1 platform.

This crank has been out for ages, maybe it shifted better with, like, 9 speed? Wider chain, and all

Because that is the nature of an "all the possible combos" system. You can't buy a Shimano, SRAM, or Campagnolo crankset in any number of chainring combinations. They have done the design and testing and the results are specific combos that shift very well because they have ramps and pins to lift and drop the chain to achieve this. This is why there is only one correct orientation for each ring in these modern chainring combos.

That’s totally what I was thinking as well. Has to be. 9 and 10 are probably the sweet spot for best overall shifting.

You’re absolutely right. I think I just needed to hear a few voices of reason. I think my expectations were a bit higher than what the rings were designed to offer.

interesting. I have the R30s with sram 11 sp that work beautifully and was planning the G30 with a campy build. i guess I'll see what happens

Interesting indeed. 68mm bb shell? Do you recall what spindle length you’re running?

Perhaps it's your FD. Something to do with the yaw design that does not throw the chain down fast enough or far enough to land on the teeth of the small ring and not the gap.

I had these with campy and they shifted fine, not spetacular but fine. At the time there was not a lot of crank choices but plenty out there now and specially when absolute black now makes sub compact rings for 5 bolt cranks.

As far is the issue, I remember this happening once in a while, the 11 speed chain fell in btw the rings, tbh I do not remember how I fixed it but remember adjusting the FD until it stoped doing it

I may look into those Absolute Black sub compact rings. 48/32 in a 110? Now we’re talking!
