Hi there,

I'm currently on a 54 Trek Madone 5 series and am considering getting Eriksen to build me a ti racing bike to replace it.

His frames generally come in under 3 lbs for a 57 so I assume a 54 would be closer to ~2.6 ish.

I have no clue what the weight of my Madone frameset is and the interweb doesn't seem to have the answer either.

I'm trying to figure out how I'll build the new bike up and knowing what the Trek's weight is would be pretty helpful in estimating how much lighter or heavier the Eriksen would be in the end.

I've even searched the forum and haven't seen anything here. If someone knows or if I'm missing something I'd appreciate some help.

Thanks a ton!

I own a Kent Eriksen.
It will be about 1 lb heavier with same build.
I would call my Eriksen about a 55cm- it is made with lighter gauge tubing. It is 3.0 lb. even with all hardware.
No way you are going to get a medium-ish size Eriksen that weighs 2.6 lb.
That said, I love my Eriksen more than any carbon bike that I have owned in the last 9 years.
How tall are you and how much do you weigh?
If you are pretty light he can build one like mine.
1" stays, 1.75 light gauge DT, 1.375 light gauge toptube. Standar 11/8 headset and Enve 1.0 fork.
This works great for me- I am 64-65 kg.
Glad to tell you more- can pm me for more info.

For sake of argument, lets put the Madone 5 at same weight as the emonda SL which is roughly 1050 grams, or 2.3 pounds. Potentially a difference of 0.5 to .75 lbs compared to Eriksen.

Don't buy a ti frame if weight is your primary driver. You can find much lighter frames at comparable prices.

Get the madone in H1 if it fits you; you get light and aero with that

Yeah, but that's a 7: he has a 5. I've got to believe the Madone 5 is around 1100 grams. The Ti frame would be in the 1350 range. So the hit would be around 250 grams.

Consider a 200 meter climb in a race and climb at 1400 m/hr (8.6 minutes). If wind resistance is 10% total power, then 1% change in mass improves climb speed by 0.83%, so I get a delta assuming 85 kg total mass of 1.2 seconds on the 200 meter climb.

Wow -- 5 @ 54 may be even more, then.

he wasn't talking about a bare frame. I figure my 60cm model is around 1300g. I didn't get a chance to weigh it when I put it together, but just subtracting known weights from it, I calculated that out. Of course the number isn't exact.
