Nice review, Francis.

You may want to note that a crescent is NOT how you should be adjusting these, rather with a 13mm cone wrench.

I know, I've only installed 13 pair of them!

Excellent review. Good catch on the [relatively] weak return spring. The other notable minus is that the calipers feel somewhat less stiff than Campy (never tried Shimano). The braking power is fine nonetheless, but when squeezing just past initial contact of the pads to the rims, the 0-Gs feel slightly spongier than Campy (try it yourself). Regarding fitment, the current 0-Gs fit Pinarello Dogma & Colnago C40 (Star fork) w/o spacers but won't fit a Colnago C50 HM (Star fork) unless you use spacers. Also, you need to get longer backnuts from 0-G for the Dogma/C40/C50 than those supplied with the brakes. On the upside, you have less weight and great absolute stopping power. Decisions, decisions...

BTW, you should use a standard 13 or 12 mm (as appropriate) open wrench or a snugly-cinched-up, small adjustable wrench to center the brakes (more contact area compared to a cone-wrench so less probability of marring the black anodizing). Use the smallest wrench that fits the flats you're wrenching. Why 13 or 12? Depending on which pair of flats (on the brake) you wrench, the width is either 13 or 12. Weird, but I checked this on both pair of 05s here (bought several months apart) and that's just how they're machined. Here are the brakes in situ:

Ugly!

I'll keep the shiny stuff. Those things look like they were built with an erector set. All angles. I think I'll hold onto my $400.

Perhaps, but they work well and are much lighter - the issue is whether you prefer more optimally functional or fashionable brakes...

Very well written.

Nice review, very objective. You have to love the OG-05's!

Great review, on a great set of brakes. Slightly off topic does anyone know what the torque specs are? I have yet to find this info. Ended up using Campy specs.

70 inch pounds.

On the mounting bolts and the cable pinch bolt. They came with the directions that were with the brakes.

Thanks. The only thing mine came with is a warranty card.
