BMC Timemachine TT Disc

I know there are naysayers on 12 sp as Campy already has it, but you will see everyone else coming out with 12 sp. Hopefully a different set of wheels from 11 sp aren’t going to be needed.

The SRAM PG-1230 Eagle 12 speed mountain cassette fits on a current standard 11-speed Shimano/SRAM freehub…or even an 8/9/10 speed freehub. Rotor will be launching 11-speed-freehub compatible 12-speed cassettes with more road-friendly ranges early next year. If you want a 10T (or 9T) small sprocket, you’re going to need a new freehub. But, if you can manage with an 11T smallest sprocket, 12 speed is not automatically incompatible with current wheels.

So…what do we all think of the new BMC TM?

So…what do we all think of the new BMC TM?
If they’re not even willing to claim that it’s faster than the old one, then… yawn

This statement:

We designed aerodynamic caliper covers to optimize the airflow around the disc brake calipers and minimize the impact on aerodynamic performance. The result is the aerodynamic performance of our Timemachine with the benefits functional integration of disc brake technology.

They are basically saying as fast as their rim brake version and with better brakes.
Believe me, if they had any shred of evidence that the disc brake version was as fast as the rim brake version, they would have put it front and center. The fact that they went with vague uninterpretable mumbo jumbo instead, hidden 3/4 of the way down the page, is proof that it is not.

I think that is " fair " to say… the burden of proving it’s faster then rim brake model is on the disc brake model. Every other mfg has stated these things but BMC choses to be vague. I still want the TM01 Disc but LanierB is right.

i TRULY do not understand why everyone think that the design’s idea is to be faster. its to STOP faster. if the bike is equally as fast and stops faster, then mission accomplished.

People need to understand that bike companies are focusing on things beyond aerodynamics

So…what do we all think of the new BMC TM?

Freaking awesome. I love my older TM01, but the brakes suck. They are weak, a pain to adjust, and changing pads requires pulling my crank on the rears. I’m a mediocre cyclist at best and don’t have the bank account to purchase new bikes. But maybe one day, or maybe I’ll just wait till this is a few years old and I can find one in my size used.

Here we go again…

I don’t care. I have an open mind. You and many others won’t stop shouting about how it’s the end of the world for bicycles.

I have repeatedly said wait and see and am excited about a new direction. Of course you can’t accept that things are changing. I get it. Change is hard for most people.

Change is not hard to accept for me. While you criticize every post I make about it, brag about your NDA and drag numbers, the rest of us moderate people on here could care less. We just like bikes.

Is that clear enough for you to read?

When the top of the line bikes from each manufacturer are going disc brake what are we going to do? Get mad and protest? Buy old frames and parts? Go tell them on Facebook how wrong they are?
How about buy the bike and have fun.

But you just said you don’t care about bikes changing technology? So which is it?

As for me, I’m happy with my lot. Won’t see me buying anything new until all my current stuff goes to pieces.

If you have an old 2011 P2 like me, you would be looking for a disc brake bike as your next bike.

Why? How much time do you really spend braking on a Tri bike? How often do you ride in the rain?

I’m not negating the advantages for commuters, CX or MTB bikes. But for the rest of us, there’s not that significant of a difference, at least not enough of a difference to have to get all new wheelsets. It’s just something new for the manufacturers to sell us

I really don’t understand how manufacturers can just abandon bringing out rim brake models.

Trek at least have a New Madone SLR in rim and disk.

So the bike may be equally as fast. And let’s say it stops faster, for the sake of argument.

But it’s also much more expensive and many times more complex.

entry level average price on one of those new aero road bikes launched last week is ~$5k. You could get a whole lot of rim brake bike for $5k.

Your maintenance costs will go up as well. Bleeding brakes, bent disc rotors… how much is your time worth?

safety > time.

Congratulations, go file that patent and I bet Zipp, ENVE, Roval, and well everyone else is now scared.

I don’t need to apply for patents for obvious ideas such as that. I already have 18 patents/patent apps. covering molecular biology/chemistry, engineering, nanotechnology, and microfluidics arrived at the hard way (at the bench, not by being a supervisor taking credit for ideas brought to them). Ill give the rim idea away for free (since it is not new or novel). Oh, and try not to be so arrogant in your reply if you can help it.

Oh, and you never addressed the point of what I was writing…that there is no difference between using the rim as a disc or a separate entity as the disc; and that we arrived where we are with disc design by very incremental advances; rather than any sort of leap (small or large).

Fair enough…but what if your wheels are a nice Zipp Super 9 and 808…? Would you not then go for something like a Trek Speedconcept or a Cervelo P5 etc…?

My point is the market for disc brake TT bikes is going to be people buying their first TT bike…or people looking to change their entire set up.

The main thing they focus on is making money; otherwise, they do not remain a company…and people do not *need *to understand that, it is just helpful to understand that if one wants to understand the motivations of a company which cause them to take certain actions and go in certain directions.

I agree with a bunch of your thoughts on the matter (discs are making inroads to bicycle design and are on their way to be the go-to braking methodology), but I think that the reasons you use to back it up are not primary in the minds of the companies which product this stuff.

“I wonder why triathlon isn’t growing?”

if the Manufacturers think it takes $5K to gain entry, then the door isn’t really open. people can talk about these nonsensical $10K-$14K bikes and that’s fine. the lift in the bottom is the real issue.

sigh …

I’m also a mediocre cyclist, and I have a question for you…How often do you change brake pads? I’ve done over 70 triathlons since 2010 (and all the associated training miles) and have yet to change a set of brake pads.

It’s not that I have to change them, but when I want to adjust the brakes or swap between training and racing wheels I can’t without it being a major issue.

Sold my 808/Super 9. No interest in a P5 or Speed Concept.

Picked up some Hed Jet Blacks? :wink:

Nah. Renting an 808/Super 9 from my shop.
