Re:
Cobalt wheels.
Yes, you can buy better performing for less, but that would be missing the point a bit.
I've got two sets, & I love them.
My comparisons are limited to the other stuff in my cupboard, which at present is a set of Hope/Mavic wheels that were OE fitment on my Whyte, a set of Spinergy's (with the PBO fibre spokes) and a set of Mavic Crossmax ST's. All are good wheels.
The Hopes are the most conventional. 36 spokes in standard 3 cross lacing, and they are a fine set of wheels that seem to put up with my 16stones just fine. The Spinergy's are quite unremarkable in terms of ride and handling (which is a good thing!), but they do seem to spin up quite nicely. The yellow spokes are a bit wild to my eye though. The Mavic's are a bit "creaky" for my liking. They use thick gauge alloy spokes in a mix of 2 cross and radial lacing. They handle nicely, but the noise is odd.
The CB Cobalts do everything the other wheels do just as well, and to be honest, in a "Pepsi challenge" I really don't think I'd be able to tell you which wheels were on my bike by feel alone (the creaking from the Mavic's aside). The crank brothers wheels do have a couple of other little bonuses to consider though;
1/ they're an absolute doddle to clean. They really only take a few seconds to wipe down after a ride and they're sparkling again, and
2/ the real reason for having them, they look absolutely ace mounted on a bike.
Admittedly, you'd be mad to pay the RRP for a set, but for the money you can get them second hand, they're pretty good wheels...
