New 2008 Trek Madone 4.5?

Waiting on delivery of a new 2008 Trek Madone 4.5 which I just purchased.
Was considering buying the Trek 1.9 with full ultegra but opted for the 4.5 carbon instead.
Its my first carbon-frame and a good step up in components too.

Any other owners of this machine have any opinions of it?

What its like to ride, is it good for long climbs?

Any replies appreciated.

I purchased a Madone 4.5 compact a month ago and I could not be happier. My LBS provided me with great service to get it just the way I wanted it.

I was a bit torn between the triple and the compact wanting the easy pedaling of the triple, but also wanting the smoother shifting of the compact. They swapped the stock 11-25 cassette with a 12-27 to bring the compact gearing a little closer to the triple on the low end and it's been a perfect compromise.

They also did a pro fitting and swapped the stock 90mm stem with a 110mm. The owner of the LBS said that a 110mm would ride much straighter and truer because of the increased rotational inertia of the handlebars on a longer stem. After riding, I can't disagree with him.

On top of that, they threw in free service for as long as I own the bike.

I originally went into the store planning on taking home the 2007 Trek 2100 Aluminum with Carbon stays, but after test riding both, the Madone was hands down so much smoother and more comfortable to ride. I am not concerned that the 4.5 is TCT carbon and not OCLV carbon because Trek has a lifetime warranty on both types.

What does your 4.5 weigh?

I haven't checked the exact weight. I'll be bringing it in for a tuneup this week. I'll tell you after that. The LBS told me that the new frame design for 2008 is a bit lighter than 2007.

I picked up my new Madone 4.5, size 54cm just a few days ago and as the weather has been suitably appalling have not managed to get out on it yet. So in a displacement activity I looked at it (mmmh, nice) then weighed it using a digital fish scale. The result was 18.5lbs, which should be reasonably accurate.

At 18.5lbs, what type of pedals/cages/extras are on it?

Mine is 52cm so we can see how much less the smaller size is.

Absolutely nothing on it, no pedals, cages, not even a coat of polish, yet. I'll be interested to see what the different frame size gives.

Do you have a triple or compact crank? The Shimano 105 triple is about 180 grams heavier (0.4 lbs)

Mine has the compact.

Forgot the triple was an option, mine has the compact as well so should be as close a match as we can get.

A few days after asking the weight, my lbs got two of the 4.5's. We looked at the 56cm with a compact.

We put it on a Park DS-1 digital scale and found the grand total was....

19.07

This does include reflectors and plastic platform pedals from a test ride.

I think for giggles, I'll go back and get the weight on a 5.1 & 5.2 they have.

Wow, that's heavy. I thought those Madones were supposed to be light?

The 4.5 is a base model Madone. The higher up in model numbers you go, the lighter they get.

If I remember right, here were two others we weighed...

5.1 was 17 pounds 7 oz for a 56cm.

5.2 was 16 pounds 7 oz for a 56cm.

Don't quote me on it though.

That sounds right.
The 6.5 is 15.38 lbs with reflectors but without pedals in a 58.

The 4.5 is basically the lowest grade madone based on a traditional seatpost and all that. I think you drop almost a pound going to the integrated mast and better fork and then all of the components and stuff adds on top of that.

I agree. The 4.5 is also the lowest grade Trek TCT carbon and is also missing the integrated headset and bottom bracket that the 5.1 and above all have.

I would say that the 4.5 is equivalent to the 2007 Trek 5000 model. The only difference between the 2 is the new frame design and better wheels on the 4.5.

I don't really consider the 4.5 a true Madone since it does not have the innovations of the 5.1 and above.

I had just assumed they were all the same and the difference between the models was the carbon material & layup quality, and component levels.

You may not consider it a true Madone, but Trek does. Baby Madone or not, I like mine just fine. Shaved a bit off the weight with a new seatpost, stem and bars that are on order. The frame design difference between the 5000 and the 4.5 is critical. Yes it is TCT Carbon but look at the geometry. The 5000 is a great bike. But it is different. That is why I spent more and bought a new 4.5 when I could have had a left over 5000 from last year.

Ditto on that. My '08 Madone 6.5 weighed in at 15.3 w/out pedals. If I put a set of ZIpp 202's on it, I'm sure it would get down in the 14's with no problem.

Don't get me wrong, My post was not a flame on the 4.5. In fact, I am a proud owner of the 4.5 as well. I too am glad that the 4.5 is a Madone because in the past, only the Madones were eligible for their crash replacement program. I don't believe that the 5000/5200 were privy to that.

the only difference in the new madone geometry is with the pro models, the regular ones have the same geometry as the 5000. The only difference from a 2006 madone and 5000 was carbon type

Just in case anyone else in interested. I finally measured the wheel factor on my 4.5 with Stock Bontrager Race wheels and Race Lite Tires 700x23c at 115PSI. Wheel factor = 2110mm
