I can tell you that your Adamo saddle is likely 290-350g depending on the model. So something like a Fizik Transiro would save you 0.2 to 0.3 lbs. A stock Dash saddle would save another 0.1 lb.
What wheels are you using? Something like a Flo 60 set weighs 1750g while a Rolf wheel of the same depth weighs 1400g, saving you 0.7 to 0.8 lbs.
What group set are you using? Electronic vs mechanical shouldn't make that much of a difference but the difference between ultegra and Red could be 0.5 to 0.7 lbs.
There are many opportunities to be a weight weenie:
- Cassettes: Rotor is 0.1 lb lighter than Red/Dura-Ace
Even for a constant uphill ride for 5 hrs, that's a 3 minute difference.
Maybe something else going on ?
I'd say it's very likely that something else is making the difference, and you're misattributing it all to weight.
As noted above, for a given speed up a hill, the weight penalty is creating maybe a ~1% difference in required torque. That's only one quarter of the difference between a 25-tooth big cog and a 26-tooth big cog, definitely not something that'll stand out that much.
If the issue is that you're bottoming out your gearing and being forced to stand, the first thing I'd check is that you're appropriately-geared for the riding that you're doing. "Appropriately geared" means that you're able to keep your torque and cadence reasonable per what your legs want, not that you simply didn't have to get off and walk. Plenty of people insist "my gearing is fine" as they climb at 40rpm, even when it's costing them rapid fatigue and a 15% loss in wattage.
What chainrings and cassette are your SC using? What chainrings and cassette did you use on the old bike?
Same gearing and wheels/tires? The only difference is the SC frame/integrated components? For example I train Aeolus 4xxx's but race on 9's. It's a small penalty on climbs but faster everywhere else.
Are you standing up more because you're running out of gears, or because your legs just want to use a standing form?
Different bikes can pedal differently from each other. Partly fit, partly how the bike flexes.
Thanks all for your thoughts on this.
Just my 2 cents
I have a feeling the SC is just heavy. My next ride will be a Canyon Speedmax 7.0 in 2020. Itâ€™ll probably come in around 18.5 lbs in a small with my Flo 60â€™s and the new 105. Thatâ€™s about 2lbs less than my current bike.
I lost 22lbs this offseason and my climbing is better than ever even early in the season. Losing weight helps if youâ€™re tackling a lot of elevation.
This included time trials with significant climbing including a 10 minute mostly hillclimb.
I am not going to say that my bike was the fastest bike ever made. It was not. But me and that bike got on well.
Went through a pile of other sexier and lighter bikes- I was slower on all of them.
My point is that there is likely something with the SC that does not suit you- Get rid of it and get something else.
You can lose half a pound by getting a carbon fiber mono pad. Depending on what cranks and chainrings you have you can probably easily lose weight there. A final place to shave weight would be your cassette. The SRAM mono block 11 speed cassettes are pretty darn light. Between those three items I guarantee you can shave 1.75 pounds if not more.
However, as the others said, weight definitely isn't your problem. The Speed Concept is a very fast bike and, give that you're riding an XL, I'm going to assume that you weigh at least 155lbs. 1.75lbs is nothing in the scope of bike + rider + nutrition.
With the weight being nearly negligible, I would start to look at the differences between the bikes for a possible answer.
How similar are the fit measurements for your P3 and SC? Same saddle height, seat setback, reach, etc.
Are you on the same saddle for both?
If you find a difference, that might explain your climbing out of the saddle and you can use that for adjusting your SC or getting a bike that can meet those fit coordinates.
Oui, mais pas de femme toute de suite (yes, but I am not ready for a woman straight away) -Stephen Roche's reply when asked whether he was okay after collapsing at the finish in the La Plagne stage of the 1987 Tour
Way back when I weighed all the frame/stuff on my P5. Frame only was 1650 and that was with stainless steel internal cable routing (they donâ€™t do that any more) I find it hard to believe the SC would be much heavier.
Aura pro with a stem would be around 1kg, I really donâ€™t think that the sc bar system is 1900 grams.
I think youâ€™re missing something...take some pics of both set ups.
