Bearings tend to be better higher up as well. I’ve got XC8 on my gnarmac bike and they are silky smooth.
Don’t believe that. They’d shout about it if they were any different.
They completely fail to sell the benefits of the more expensive models so over the years I’ve become convinced there isn’t any. Weight saving is minimal until you get to the Ti axles.
Carbon body over standard composite – so? smash it on a rock hard enough and either will break.
Hollow axle – saves 5g?! Benefit? Possibly stiffer but they dont’ say. Noticably stiffer? who knows
Oversized axle (and other bits) – 15g off the cheapest. But pedal body is same size so *presumably* the bearings are smaller which doesn’t sound like a good idea.
Weight savings are even less on the XC pedals….
My experience is that they last ages but the rebuild kits are expensive so best off running whatever you get at the best price and replacing the entire pedal when the bearings (finally) give up. The second generation pedals went sloppy quickly, everything else has been fine.
