Rated 5 out of 5 by from Great bike amazing ride As a former pro cyclist I am blown away by this bike. First following in love with Cannondales geometry it fits me like a glove. This bike just wants to go it is stiff and super responsive I can't say enough good things. Having ridden 10k bikes in my day there is not much of a difference with this one. If you need a bike that can take a beating while delivering a 10k ride and your on a budget this is the bike for you. Best alloy bike on the market. Bike weight 17ish with heavy cages in a size 58 can easily shed a pound or more with a pair of race wheels and lighter cages.

Rated 5 out of 5 by from Great Ride The is a great ride. I have ridden it several times and really enjoy it. The gears, the brakes and the wheels perform great. I prefer the aluminum frame over carbon but the carbon forks do make a difference.

Can I use my other wheel sets with this CAAD12 with the BB30a cranks and the BB30 bottom bracket, or do they have to be redished for this asymetric crankset.

Asked by: Fort Smith
We recommend contacting a bike shop directly and provide them with the exact specs on your wheelset to see if it will fit the CAAD12 3 Ultegra Bike.

Why isn't the fork Chrome? It would look much better.

Asked by: Johansen the chemist
Because the gawdiness of chrome would distract drivers and create accidents.

I live in an area with lots of steep hills and I use a 12-32 rear cassette on my current roadbike and I am curious to know if the Caad12 (105 or Ultegra) can accommodate this size cassette? I realize that I would have to change out the rear derailleur.

Asked by: jpbrown
This bike can accommodate a 12-32 rear cassette.

I'm looking to buy the bike in red color, how can i do that since the only color it shows for my size is black. Also my current gears are 50/34 and 11-32, can i fit a similar ratio to this bike?

Asked by: Kiran
We do have plans to restock the red color. Please contact us by phone at 1 (800) 426-4840 for future availability information. The gears on this bike are 52/36 and 11-28. In order to get the same ratio that you currently have on your bike, you would need to change out most, if not all, of the drivetrain components.
