New TT bike - BMC Time Machine TT02

Peloton Shelter Dog
I averaged that for a TT a couple of years back, but it was only about 8 miles. And my position on the bike was terrible. I would be faster now on the P3. Didn't get to TT too much this year, I've had 3 races cancelled in the last month due to flooding and other reasons. Two more TT's left, weather permitting.

If this is your first TT bike OP that you built up yourself, how did you figure out the bike size and how high to position the handlebar?
I am considering buying or building a TT bike and am not young and so am concerned that an overly low handlebar maybe an issue for neck comfort in particular.
Any advice?
Thanks

Regardless, I'm still fat so my power to weight ratio sucks.

Not even close, I built the bike on Wednesday night, test rode it on Thursday, raced it Saturday. Also, no matter how good my position is (which it is far from good) I am still 5'10" and weigh 210 - 215 pounds. No matter what I am going to be fighting a lot of wind.

I did already notice those numbers meant your drag is pretty high.
Still ... what matters is that you have a nice new bike and that you have fun riding it

Honestly, I don't have fun riding it. It hurts like hell!!!! That's part of racing though.

Sorry, I'm missing something. How does high cadence and high speeds slow you down? I agree that when i watch a TT normally you see the guys running a large gear with a lower cadence then you would normally thing is right during a race. I'm just not understanding the reasoning behind this.
Your feet move against the wind more than your body does and so they generate quite a lot of drag for their size.
This is why TT'ers even use shoe covers to increase the aeroness of the feet.
The higher your cadence ... the faster your foot is "kicking against the wind" and so the more it will slow you down.
The difference isn't huge nor is it even big ... but for time trial races it can mean the difference between winning and not even being near the podium since the effect increases exponentially with speed increase.

Updated pictures with the new wheels. Please ignore the grime and the crank position. That is the temporary crankset, I'll be putting the Quarq on it for TT's.

Certainly for a TT bike. Just a question though. Do you race the Tour of the Catskills? Do you race a standard up devil's kitchen? Not saying it can't be done, not saying it shouldn't be done, I know many who do. But I also know some people who re-gear for races like that with compacts so they don't leave it all on the hill.
More curious than anything else.

Do you know the size of the seat post front to back side to side in mm? I have the same frame and have been searching for a seat post of over 6 months. BMC doesn't make them anymore

I wish I could help but I haven't owned this bike in several years.

How old are you? When I was 35 years old I could run in the 23mph range with a standard lugged-steel frame road-bike, and the guys who used to win back then, 25 years ago, were running almost 30mph on fancy bikes like this with disc wheels. I don't think I would have any use for a bike that cost many thousands of dollars unless I could go close to 25 or 26mph on a standard road bike for the distance of a time trial, because it would not be the hardware that was keeping me from coming close to winning.

If I were close enough for it to make a difference in winning, if on equipment like Eddie Merckx used to set his hour record a half-century ago I could go around 27mph in a TT, then I might win some local races after dropping the thousands on equipment, but as it is someone who can only muster 23 or 24mph on a bike with round steel tubing, would never be able to buy the six or seven mph needed to win anything. I don't mind finishing in the middle of the results of a time-trial today any more than I minded not winning by finishing in the top ten-percent 25 years ago, so it still a few decades later does not seem to make any sense to let participants in an athletic sport buy speed, to let their speed in the event depend on how much money they have instead of how much athletic ability they have, and it certainly does not make sense to feel good about buying speed, especially when it is not competitive anyway. If you are a competitive bicycle racer, you do not have to buy it, a sponsor or team you belong to will.

it is not about you at all, and the thread is on the front page of the forum so it is fair game. 25 years ago when i could run a standard lugged-steel bike up into the 23mph bracket, i asked a local bicycle dealer who raced and sold fancy time-trial equipment how much time all that fancy aero bicycle and helmet and other equipment was worth in a time-trial of a dozen miles or so, and they said "two or three minutes". So even if i dropped the thousands of dollars on high-end equipment it would cost for those two or three minutes, i would still be four or more minutes shy of ever winning a bicycle time-trial race, or any other bicycle race for that matter. So it did not seem to make any sense to spend thousands of dollars to go from being a slow or average bicycle racer, to being a little bit faster slow or average bicycle racer.

I’ll continue to enjoy riding amazing bikes.
I probably don’t “need” this one either. Luckily I’m not worried about what you think I should be riding.
