Review: Giant Trance 2
Love my 2014 Trance, but disappointed to read that RC likes the bike's climbing chops. I guess I have to stop blaming the bike.

Review: Race Face’s New Cinch Oval Ring
@justanotherusername: Thanks? Maybe I wasn't clear, I'm not defending biopace, they're trash for trying to climb any significant grade. I get that modern oval rings make it easier to get through the dead spot, and therefore probably make it easier to climb, I'm just confused about how they might smooth out power delivery as people often claim. I've been to the absolute black site, didn't see anything that has any credible explanation for this. You're getting more mechanical advantage at the point where you already produce the most power - this should cause more of a power spike and therefore accentuate the pulsating feeling. The only way to get rid of that pulsating feeling with a modern oval ring would be to move your feet slower through the power stroke, but I don't think most people pedal like that. Or maybe they do, or maybe an oval ring forces you to... I don't know. But I was hoping someone with a solid understanding of mechanical advantage prinicples could help me out.

Review: Race Face’s New Cinch Oval Ring
@shortcuttomoncton: on flat cruisey rides it might make sense, hammering through the power zone on a 40t round ring would feel the same as hammering through the power zone on a 42t biopace, and as long as you have enough momentum to carry you to the next power zone without having to put any power in at the dead spot you'll be okay. But when you're climbing something so steep there is no coasting action, and you need to put power through every degree of rotation in the cranks to keep moving, biopace is a total flop.

Review: Race Face’s New Cinch Oval Ring
I run round rings on all my nice bikes, but my commuter has old BioPace chainrings that I've never bothered to replace. BioPace actually seems to have a very smooth power delivery when cruising or hammering, and it makes me wonder how modern oval rings actually help with this. Picture this - for an ideal constant wheel speed, a round ring would have a constant rotational speed, a biopace ring would be rotating faster in the "power zone" and slower in the "dead zone", and a modern oval ring rotates slower in the "power zone" and faster in the "dead zone". With most riders' tendencies to smash through the power zone and linger in the dead spot, wouldn't modern oval rings just accentuate that pulsating feeling? Please someone educate me!

Review: Race Face’s New Cinch Oval Ring
I'm running BioPace on my commuter. It's actually the opposite of modern oval rings, the smaller diameter is timed at the power stroke, designed to force your cadence to slow down in the dead spots which was thought to be better for your knees or something..

Bike Check: Kellys Bike Noid 90 29er - European DH Cup 2018
@emptybox: if you want to get pedantic, Santa Cruz had a patent on VPP, which was described as having two short counter-rotating links. DW and Giant's systems may have a dynamic (virtual) pivot point, and so does Horst link and pretty much anything that isn't a single pivot, but that doesn't make them VPP.
