Other than the CB7 and CB6 offering 20% better braking than the CB1's (I think I read that correctly?)...what are the differences in the brakesets in terms of weight savings, aluminum processing, etc.?

Thanks.

My C7 brakes work well, but the finishing is disappointing. Off the bike, when you squeeze the calipers, you can feel mild metal-on-metal grinding between the arms. I'll probably disassemble them at some point and try to remedy that.

I used to have some CB1's . They don't really stop you that well. After trying lots of brake pads I found these Gooey brake pads . There quite sticky and really made a big difference. http://www.ebay.co.uk/itm/Gooey-Cartrid ... 19c0bcff9b" onclick="window.open(this.href);return false;" onclick="window.open(this.href);return false;

They do wear quite quick in the rain, so just keep an eye on the wear .

I think the C7s are braking ok for their weight, but you need matching rims and pads, as there's not really a lot of "error margin". The feeling of flex in the calipers when going into a switchback hard is something to get used to. A lowlight for me, after riding them all season, is that they tend to seize up because of the bushings (instead of bearings), so the calipers don't open back up completely themselves. They do if you pull them open by hand.

Yes the seizing is an issue, especially after a stage in the rain. Sometimes a little lube will help, but I need to disassemble and clean up the rough edges on mine every so often.'

As for braking power they are virtually on par with the best IF you use brand new pads (DA on alloy or Reynolds blue on carbon) or very wide rims (eg: Firecrest). They have extra leverage when the calipers are spread further apart.

A follow-up question:

What other brakes (in either black or gold, preferably) outperform the C6 in the ~$150-$200 price range? Think less maintenance = better.

I'm a pretty big proponent of the TRP 920, they tend to run around 255 grams(I received the heaviest pair I've ever seen at 262, most run 250-255), come with nice pads(swisstop or koolstop), have great power and modulation and mine were a pinch to install and I haven't "maintained" them in about 2 years. Set and forget. Kinda heavy by WW standards but lighter than anything from the big 3.

Can be had for $100 usually.

Planet - X sit in that range. Maybe it's time for a C8!

I would put the TRP 920's in the same stopping power as the Plane-X/Featherlite CNC, both excellent.

Im riding Planet x brakes . They stop much better than the KCNC brakes . Theres a bit of a weight gain but you gain quite a few extra yards in stopping power .
