2004 Dura Ace all that much lighter? Cannondale R3000/2000(11 posts)

2004 Dura Ace all that much lighter? Cannondale R3000/2000K-Man
Dec 1, 2003 10:26 AM
Just courious about something I read on a post from earlier last week. Someone picked up a new 2004 Cannondale R3000 with a "claimed" weight of 15.5lbs. I have a 2004 R2000 that has an "actual" weight of 18.5lbs. I have a hard time seeing where the R3000 is loosing 3lbs.
I have no idea about what size frame they were quoting a weight for, but still 3 lbs is a lot of weight difference between the two.

Any thoughts?

the 15.5 weight is likely way off --

First off, I'm the one who got the new R3000. I did weigh it sans pedals and it came out to around 15.5 lbs. Now, the scale could've been off by a half a pound or so, etc. etc. Anyway, since I have free time, I decided to go off and try to determine how much these bikes SHOULD way in comparison.

The difference between the two bikes:

R2000: Slice Ultra Si - 390 g
R3000: Slice Si, full carbon - 310 g

R2000: 3TTT Forgie XL - 240 g
R3000: 3TTT Less XL - 215 g

R2000: 3TTT Forgie XL - 185 g
R3000: 3TTT Less Xl - 135 g

R2000: Fi'zi:k Poggio - 240 g
R3000: Fi'zi:k Arione - 230 g

So the components on the R2000 weigh 175 g more than the components on the R3000.

GROUP (Crank, Chain, Rear Cogs, Bottom Bracket, Front Derailleur, Rear Derailleur, Shifters, Brakeset)
R2000: Ultegra double - 2494 g
R2000: Ultegra triple - 2624 g
R3000: Dura-Ace - 2180

So the R2000 double weighs 314 g more than the R3000, and the R2000 triple weighs 444 g more than the R3000.

Finally, the R2000 double weighs 489 g (1.078 lbs) more and the R3000 triple weighs 619 g (1.365 lbs) more than the R3000.

Clearly this does not explain the weight difference. I have a 56 cm frame, and weighed the bike without pedals and bottle cages. How about you?

I don't think my scale was that far off, and it didn't feel much heavier than 16 lbs, but I'll be sure to weigh it again when I get home for winter break.
It's possible......divve

....but unlikely.

My R3000 is about 16.3 with pedals. The last time I weighed it the build was:

CAAD7 size 58 - ball-burnished (no paint weight ~100g less)
Campagnolo Record '03 gruppo
ITM Millennium Carbon 44cm handlebar
ITM Millennium Carbon 120mm stem
ITM Millennium Carbon 250mm seatpost
ITM bar tape
Campagnolo asymmetric post clamp
Selle Italia SLR TransAm seat
Custom wheelset 28h OP/Record/CX Ray
Michelin Pro Race tires
Michelin A1 service course tubes
2x Tune carbon bottle cages (8g a piece with alloy screws)
Speedplay Zero steel pedals
So it's very possible...kevinacohn

Forgot about that... my frame is also anodized (matte black), so there's some more weight off the R2000.

If you take into account the smaller frame (56 cm vs. 58 cm) and remove the pedals, you're very, very close to 15.5 lbs. Maybe it's actually 16 lbs. Like I said, I'll check again when I get back.

If the 04 R2000s Slice Ultra Si fork is comparable to previous years alloy steerer Si forks, it weighs well over 500 grams.
That would also account for some of the difference...kevinacohn

...although I was told by Cannondale that the weight is 390 grams.

Mine is a 2004 58 R2000 with Crank Brother Egg Beater Pedals. I weighed the bike on my digital scale which is pretty accurate (at least within a few grams for the entire bike).
Scale has a 13lb max limit so I weighed seperately each wheel with tires and cassette, pedals, and then the remaining frame/components. I'll double check my scrap paper at home tonight, but I swear it was totaling @ 18.5 lbs. (no bottle cages).

By the way does your saddle creak/sweak? The bike rides very stealth except for the creaking saddle. I have an extra Flite TT that I plan on switching over to make sure it's not the carbon post.

Saturday morning I put the bike through its paces. Two laps around Central Park at a swift pace (with some serious crosswind) and the bike performed magnificently.

I know that everyone complains about the "harshness" of the CAAD7 ride, but I couldn't be more comfortable on the bike. The bike is extremely stiff, especially in the down tube and bottom bracket, which is important for me because I like to do most of my climbing while standing. The only noise the bike makes is the sound of the rear cogs turning... a sound that I love to hear :-).

Dura-Ace 10-speed is fantastic. The shifting is absolutely amazing... requires almost no effort to shift. I had no problems shifting under load (during a standing climb) with either derailleur.

Very, very pleased with this bike. I'd recommend every part of the bike to someone looking to upgrade or replace parts...

Any suggestions for water bottle cages?
Saddle creakTmw

Mine had that saddle creak and it was the seatpost gripping the rails of the saddle badly. I got a Thompson Elite, fitted and forgot.
Hope that helps.

I was at my LBS last week and they just received a new black beauty R3000 with the new D/A 10 sp. It tipped the scales at the shop at 16.4 LBS.
