Cyclocross Specific Components

From Cyclocross Magazine:

The continuing popularity of cyclocross has only made the need for more CX specific components more evident. For the 2012 model year, Shimano will introduce two new cranks, a new front derailleur, and two different cantilever brakes for CX use:

FC-CX50 and FC-CX70: The new CX cranks will have 46-36T gearing and Hollowtech II construction for maximum power transfer

FD-CX70: The new front derailleur is designed specifically for used\ with the new crank gear ratios as well as optimized for the harsh conditions associated with CX racing.
BR-CX50 and BR-CX70: The new cantilever brakes have better clearance compared to the BR-M550 and the performance of Super SLR. The BR-CX70 has the additional benefit of using cartridge road brake pads for easy pad replacement.

CX50 components will be available November 2011 and CX70 available August 2011

Missing: 130mm disc hub.

Also I kind of wish I would've waited and not gotten a non series Octalink triple.

I also hope they sell the 130 bcd 46 & 36t chainring as an individual item.

If those brakes work as well as R550s at a lighter weight, they're a winner.

Also missing: serviceable brifters

And why are they still insisting on link wires for their brakes?

The top-pull derailleurs are nice.

Liability and consistent setup. For the average Joe they are easier. You and I want more control over our setups. I'm wondering why they didn't include a barrel adjuster into the brake. They are so nice for wheel swaps.

Work great. Easy to set up. Doesn't stop you from using a straddle cable if you wish.

you need 110 for a 36 tooth

Just think of all the wet muddy grass that won't get caught in the cable pulley. That's where my current bike really gunks up.

I got all excited that there would be a hollow 46t chainring like 6700 or DA. No such luck, making the cranks nothing special to me.

Brakes look nice though, and the top pull front derailleurs are excellent.

True: (that's what I ment to write).

A company other than Campagnolo makes derailers and chainrings and stuff? Wow! ..Why?

Andy_K 

The average Joe probably really does want more control over his setup. He just thinks he wants brakes with better power. Several years ago I went through a period where I kept going into my LBS trying to get them to sell me one of the shorter link wires I read about on Sheldon's site. They insisted that what I really needed was a straddle cable. They weakened their credibility by claiming that the shorter link wire didn't exist, so I ordered it over the internet and found that while it did help somewhat, they were really right about the straddle cable.

As for the barrel adjuster, I feel like the link wire sort of makes that not viable -- not completely, but sort of.

Andy_K 

I was thinking that if any company was truly serious about coming out with cyclcross-specific components they'd make an 8-speed cassette and shifters that are as good as their 10-speed stuff (and maybe a bit lighter). A rear derailleur optimized for a 1x8 setup would be nice too. But maybe this kind of stuff only appeals to us non-sponsored middle tier and lower racers who don't have the legs for a big ring.

Cynikal 

I guess that was an indirect point of mine. Shimano's use of the link wire has limited then to what is fast becoming an industry standard. If I was designing for Shimano I would have aimed at the Shorty Ultimate but less expensive.

That's the beauty of the shimergo set up!
