Nope, it lives under the rounded "Uno" nameplate.

It appears all that sits under the round cover that says UNO on it.

Will take a look at the vids when I get home but that cassette really does sound promising!!! I'll be keeping an eye on that

Oh well, that cassette certain seems light but probably it'll wear out faster than a package of sweets after a long training ride...

Nice for show bikes, not really suitable for everyday riding (especially when you're on a budget...)

Looks fab actually, Rotor seem to have done a great job, but does it offer any single advantage over e-shift other than no battery?

People comparing eletronic groupsets (wired or not) to this didn't quite get the point imo. This is more like an alternative to mechanical groupsets, it can be fitted to any mechanical ready frame that have internal routing and at least for shifter cables is a set and forget system, and I quite like the appeal of this.
The only downside is that the price is not really competitive, Sram RED mechanical and Dura Ace are much much cheaper than $3000, I think they really blew any chance of competitiveness in this market with this price point.

Sorry 10g weight saving over sram red equivalent is nothing. I don't see the advantage. Would be a pain on a internally routed bike. Cutting and bleeding 4 hydo lines. Plus what kind of wonky adapters do they use for standard cable stops on existing bikes to hold a solid hydro line in place? The alternative is wireless electronic. Routing is no longer a issue period. Mechanical ready frame or not wireless just bolts on it doesn't care. I'm hoping for more competition from Shimano and cheaper non red version from sram.

Its a innovation that they got it dialed in and working but for what application? What can it do better then whats already available. Not to sound like a broken record but Etap is freaking wireless. How is adding a hydraulic hose a solution to even a conventional cables system. Maintenance?

if you are using rim brakes the system never needs to be bled, that's why I mentioned above that the system is set and forget, in theory you'll never have to do maintenance on the aforementioned parts

Realistically... Is it actually going to be retailing at $3000/€2000+

Isn't sram force rrp over £1000? In reality this will probably be priced between dura ace and dura ace Di2.

I'm really interested in this cassette. Are there any more pictures anywhere? If it's 25g ligher than Red, that means it's also 55g lighter than DA. That's a huge percentage for what seems like a relatively similar design. Is the cassette spacing any different?

I run mtb dics right now that has not been bleed since they put in use i 2013. So once installed theoretically its just going to work for a very long time most likely longer than you keep the bike. Again at least in theory.

I admit that the looks aren't as bad as I initially thought but when people call hydraulic shifter or brake a "set and forget" system it makes me laugh. I adjust my cables about twice a year. It's nice that a company is willing to try and stir things up a bit but the timing definitely could have been better.

Semi related, is that a new R3 Disc? I though the previous models were only compatible with that slk crank?


Um, no? Why would it be?


Might have mis understood, but was under the impression, they shifted to the FSA with more of an offset, to allow them to keep the same length chainstays and go 135mm rear spacing.

from bike radar:
To keep the R3's racy handling, Cérvelo's engineers managed to maintain the same short chainstay length of 405mm, rather than having to shift to the longer 415mm recommended by disc brake manufacturers. Cervélo achieved this by using a custom FSA SL-K crank with a 5mm offset to ensure the correct chainline.

Oh yeah :oops: My mistake, totally forgot about chainline.

Still, I'd have thought it more likely they were using a modified Rotor crank than a modified frame but I don't know. I know someone who's there for the launch though, I could ask when he's back.
