http://redkiteprayer.com/2015/01/bmc-tmr01-part-ii/Here is the take away if you want the short story.....
"I’ve ridden bikes that are stiffer at the bottom bracket. I’ve ridden bikes that were more comfortable in the saddle. I’ve ridden bikes that were also fast, perhaps faster than this one. What I haven’t done, ever, is ride a bike that had as compelling a blend of features as this one. Sprinting on the TMR01 was a better, more satisfying experience than my experience with the Cervelo S5. It was also a good deal more comfortable; freeing those seatstays of a rear brake can make an appreciable difference. That the bike was this quick was a shock.
I’ve reviewed one other aero bike that was quick the way this is and still maintained some comfort and road feel; it also weighed in the same neighborhood—a bit less, actually. That bike was the Litespeed C1R. I liked that bike a lot, but on technical descents and under a full sprint there was a bit of lash in the frame; the wheels wouldn’t stay in plane with each other. The practical effect wasn’t that I felt like I couldn’t sprint on the bike, it was that I tended to back off my out-of-the-saddle efforts just a bit in order to focus on keeping the bike pointed exactly where I wanted it to go. The TMR01 didn’t have that issue.
The TMR01 is a remarkable bike, one that offers a lively feel along with terrific stiffness. It’s a combination of features that I honestly didn’t expect from BMC. Why not, I’m at pains to say. Though I’ve had high regard for their work, the constellation of features was something that, perhaps, I thought was beyond their engineering team. Let’s not forget that this is their first aero road frame (even if it is an adaptation of the TM01 time trial frame), which is all the more impressive when you consider how many frame designs Cervelo has been through.
Were I buying a carbon fiber bike right now, it would almost certainly be an aero road frame. Why not capitalize on a feature of the material steel and ti can’t touch? And in making my short list of bikes that I’d consider for purchase, I’d put the TMR01 in my top three choices. It’s that good."
