Weight Weenies

Thinking of buying a TT bike, and since I have a powermeter on my Orca with BB30, it would be a good idea to maybe get a bike with BB30 as well, so I can put the crankset on the TT bike. But I have no clue which bikes have BB30. I'm guessing that the Cannondale Slice should have it?

Rotor make a threaded BB which will accommodate many BB30 cranksets in threaded frames.

Very interesting as it's Rotor 3D+ cranks I have. Is it the BSA30 cups you're refering to?

Yes BB30 cups it is. Specialized, Cannondale, Focus, Boardman is some TT frames with BB30.

Cool, that seems to expand the possibilities quite a bit What do the cups retail for here in DK?

the BMC TM01/02 has a BB30 bottom bracket.

Not yet mentioned, Felt DA and upcoming 2013 B12 are BB30.

It accomodates some BB33 cranks. Just the SRAM 975/950 and the Rotor 3d+. It won't do the a standard RED BB30 crank, Hollowgram, or Specialized crankset for example.

You can fit a Rotor 3D+ to almost any frame if you get the appropriate bearings or cups. The only notable exceptions I'm aware of is that there is no way to fit it to a BB90 frame such as the Trek Speed Concept 9 series, or to a frame with an Italian threaded BB:

QR CD0.1 and Illicito are both BB30

BTW if you are trying to use an adaptor to go from threaded to BB30 you better make sure that the spindle is long enough. BB30 native cranks have a shorter spindle IIRC

Added another question to this thread since I have gotten a bit more experience about TT'ing and triathlon bikes.

TT and tri bikes seem to be a bit the same, but when reading reviews it seems that some of the aero bikes emphasize comfort for triathletes when they're doing 180 km's or so, which means that when you power through the frame can have some flex. As I need a bike for TT'ing, between 20-40 km's or so, I basically want a frame that's stiff.

I was actually thinking about buying a Felt B12, until I read that it was pretty flexy in the BB area. I'm a pretty powerful rider so I don't doubt that I would be annoyed with a flexy frame.

But what to look for then? Argon18? Cervelo? Cannondale? I really like the look of the Argon18 bikes, but have read several places that they're not overly aero?

Seems like you and me are in the same boat, both are looking for a new TT bike. First one for me. I looked around alot and the bike that caught my eye the most is the new Canyon Speedmax CF EVO. Will ofcourse have to wait for reviews and more info but it seems to have great value and according to Canyon "Mechov got up to 47kph at 270 Watts with a Cda of 0.18". Prices gonna start at ~4000 euro for a Ultegra Di2 bike!
