Surprised, as didn't see it coming. Great design for steel too. It would be interesting to see what the ride is like between the two.
I can certainly say that the ride on the carbon Liscio was bloody superb
Interesting article, with some great lines ...
But the levers need more work ...
Can't wait for Eurobike ...

Hopefully their final product doesn't look so superglued together, but I think that this solution will be getting my money, better start saving for it and a Di2 upgrade!!

Interesting lever shape - Given that currently the Ultegra levers can be had for about $400 a pair, $599 for the levers and calipers is pretty good.
Ribble recently had the full 13 piece Ultegra Di2 setup fior $1,500. Sell the calipers and shifters to recoup $400, and then buy the Formula/TRP brakes and you have full hydro with electronic shifting.
It will be interesting to see what the SRAM system looks like too.
Hurry up guys .....
We managed to fit the 203mm Rotors both Front and Rear on the Tandem yesterday, hopefully test riding tonight as long as my stoker gets off work on time.
I didn't think the rear was going to clear the chainstay and as such I didn't have the correct R-203 bracket available, it turns out there was a big spacer on the hub that I removed to create about 7mm of clearance with the 203mm rotor fitted to the rear. We've made up a temporary bracket using spacers and shims, its not too neat but structually sound and it should work fine until the propper bracket arrives.
The bike looks very mean with the big rotors, we will bed them in this week and build up some trust before attempting some serious climbing next week. I'll put some pictures up in the next few days, I am hopeful that this will provide the braking performance and consistancy we've been looking for.
Pics, or no claiming "mean-ness" !!
Not quite road bike disc yet but could be an option to look cool and stay cool.
I guess with a 11-36 you could just run a single ring up front?

Offered in 28 and 32 hole configurations for 130 mm road, 135 mm QR disc mountain bike, and 142×12 mm disc mountain bike. Interchangeable end caps are included on mountain bike hubs.
20 and 24 hole road hubs coming soon.
I'll get some pics this week, brake power is significantly increased which I suspect is due to the larger rotor size. The bigger rotor seems more effected by flex in the frame and fork so you can hear the pads rub from time to time.
I can't do stoppies on the tandem but at full power the wheel is on the verge of locking so I think its as good as I can hope for with a cable setup.
damn it - that'd be a cool pic.
Sven to race Cyclocross nex year using the Colnago/Formula Di2 disc system for 2013 ..
Formula Di2 road discs: Good enough for Nys
No EPS version in the works though as Campagnolo were not willing to colaborate.
SRAM's new road caliper .... ?
Plenty more pics here
Looks likely since it appears to be smaller with a more aero looking shape.
Here they are, sorry my photographer skills are not so good!
These are the Bengal MB700T calipers with Avid 203mm Rotors.
Just had a better read of the blurb on the new Viaje (pronounced vee-aye-eh), and noticed this little blurb ;
Note my highlighting ...... Now that is something I'd LOVE to see on the Liscio
Lets keep our fingers crossed
Just had a look at their site, but then saw the prices $US 700 for a rear hub, $300 for a front, and $250 for the cassette
Ummmm, I think I'll pass .....
That might not be the best idea either, I've seen pics of a collapsed frame (downtube failed) due to a heavy rider brake testing with a disk brake on a 'dale touring frame - broke both his wrists, luckily he was wearing a motorcycle helmet.
I ride, therefore I am.

the amount of power you can transmit to the disc pads is exactly the same for cable and hydraulic systems.
Please be nice to me, I'm not very bright.
So? Not sure I get your point...

Although I have cable discs, I disagree. If that were the case, most cars would still have cable brakes and clutches, since they are obviously cheaper to manufacture. Some cars may still have cable clutches, but I think they would be hard to find in new cars.
I remember my father telling me about the horrible cable braked cars of many years ago.
Don't get me wrong. Cable discs work fine for the rotor sizes I've chosen. It's just that if my drop bar levers were hydraulic, I might be able to run a 160mm rotor instead of a 185. Having said that, I like cables and so might be one of the last to convert to hydraulic when available.
Hydraulic fluid doesn't impart any magical 'power-up' qualities to the brake system. It simply transfers energy from your hand to the pads, the same as a lever would do or a cable. The amount of leverage from hands to pad can be measured by the amount of lever travel to the amount of pad travel but not the method of transfer. Cable stretch may be the same as hose swell or trapped air compression so that isn't really a factor either. The difference you feel that you may interpret as power comes from the hydraulic system being able to move opposing pistons, sometimes 4 or even 6, to apply pressure to both sides of the disc over a greater swept area. Cable systems like AVID have one fixed pad and one moving pad which applies pressure and relies on the slight bending of the rotor to effect a squeeze of the disc. The difference in actual clamping pressure is insignificant but the difference in the range of modulation is. Hydraulic systems have much better feel (comparing AVID BB5 to AVID Juicy) and this translates into better braking but not necessarily better brakes.
The cable systems of old cars weren't much worse than the hydraulic systems of the same era. Automotive cable operated brake development virtually ceased when hydraulic systems became available.
Car brakes have engine vacuum assisted brake boosters amplify the braking pressure... so the use of fluid over cable does allow "power up" qualities... not really much use on a velo unless you want to shove a hose into your engine .
found a CX that looks the goods:
http://www.bikerumor.com/2012/04/24/loo ... roduction/
that's just over 8kgs. so you can imagine with some decent wheels and normal tyres, you'd have a great bike.
only problem will be cost...
EDIT: $3k US for the frame...
I think you'll find that the main reason for vacuum assistance in auto mobiles is that we need to preserve the pathetic leg muscles of the pilots, so that they can actually stop a car without imparting too much effort.
Same reason as why the cars with auto's have a HUGE brake pedal.
I won't even get started about brake pad materials and useless GM Holden brake feel .....
Try stopping a car rolling down a hill in neutral with the engine turned off... You lose a huge amount of braking force.
