Shimano RS11 Weight

In today's blog entry, let us weigh the Shimano RS11.

The wheels are used, with about 1500 kms on them. The hubs were recently repacked by a competent mechanic. Please take note that the weighing scale is not on the professional side and there are no means for me to calibrate it.


The front wheel, without skewers weigh 829 grams.


The rear wheel, without skewers weigh 1104 grams.



The skewers both weigh 123 grams. This brings us to a total of 2,056 grams. The wheels, without skewers, weigh 1,933 grams. Shimano's press release was 1,848 grams. 85 grams difference is not bad.

Ride safe!

American Classic 420 Aero 3 Wheelset

I have no idea of the exact month when they released the new 2016 American Classic 420 Aero 3 wheelset but since it's almost the end of June and bicycle parts manufacturers start to release next year's parts by the last quarter of the previous year, there should be plenty of photo resources from cyclists all over the internet. But this is not the case. Until this writing, you can only see product photos from manufacturer's website. What we need are photos of it on real bikes, bikes that people use on locations that exists. This made the wheel picking very hard as I have four other choices to ponder on. To make things difficult, I am not a fan of AC's three spoke group, aesthetically.

There are lots of literature, both formal and informal, on Fulcrums, Mavics, or even Shimanos but none so far for American Classic's newest 420 Aero 3 wheelset. I hope that this photo will reach more users who are considering the new wheels.

This is not a review of the wheelset as this is just acquired with zero mileage so far. I hope to do a better review after a few thousand miles.

But for the shallow side of things, a weigh in is a must to get that gear acquisition high that justifies that load of cash you just blew.

Some more photos!


The new 3 group spoke pattern of the 420 Aero 3 is pretty sweet. More balanced looking compared to the previous style of last generation of 420 Aeros.


At this point, I'm glad I picked this wheelset over the Fulcrum Racing Quattro LG.


This wheelset looks perfect with the 24mm Continental Grand Prix 4000 S II.


Prior to wheelset change, this bike weighed a quite reasonable 8.42 kilograms as seen in my previous blog entry. Before the frame change, my Cannondale CAAD8 bike weighed 8.98 kilograms.

The weight of my bike prior to wheelset change. Take note that my bike was squeaky clean when weighed.

New weight with the 420 Aero 3 installed. 
That is a total of 760 grams difference! I always thought that my RS11s were light. Now they felt like stone wheels they used in the Flintstones cartoons. My next blog entry will be weighing the Shimano RS11.

Cannondale CAAD8 Frame Set Weight

Out with the old and in with the new. Relatively new, that is. 

I have to do some unloading to give way to some "greening" on this side of the fence. A shift from aluminum alloy to carbon fiber frame material should fuel that cycling fire.

Check out my previous blog entry when I acquired the Giant TCR Composite.

First to go is the "old" 2015 Cannondale CAAD8 frameset. The tag at the bottom indicates probably the production date, dated 2014. This is not really that old. The TCR is a 2013 model, probably made in 2012.

In a ceremonious eve of its releasing, I decided to clean, wax, and buff the frame set then weigh it.

For comparison between my frames, this entry has the weights of the Giant TCR Composite frame and fork.

Enough of the blabbering!

Cannondale CAAD8 frame - 1575 grams
These are the parts installed at the time of weighing.
  • SM-BBR60 Bottom Bracket
  • Seat Post Clamp/Collar
  • Shimano FD Clamp

Cannondale CAAD8 Fork - 569 grams
Crazy how this manages to weigh over 550 grams. The new CAAD12 Hi-Mod fork weighs only 280 grams! 20 grams lighter than the regular CAAD12 forks.

Cannondale CAAD8 Weight

Together, without the bb and clamps, the Cannondale CAAD8 frame set weighs a little over 2 kilos. Its funny how you get perturbed while staring at the quantitative side of cycling when all worries go away with just one stroke of the crank.

Unveiling of Bike

I present to you the beta version of the bike. Still in test mode/break-in period. There are many things that needed to be changed here such as the bar tapes and wheelset. But that will come in later.

2013 Giant TCR Composite

Here it is built! I can't wait to take this for a spin tonight.


8.42 kilos is a good start. I'm 1.6 kilos away from reaching the UCI limit. 


She's now home.

Check out my previous entry for frame weight values.

2013 Giant TCR Composite Frameset Weight (Size M)

To all those who are wondering how a Giant TCR Composite size M weighs, this is it.

My educated guess is that it does not weigh any less than the latest aluminum alloy offerings currently out there.

For comparison, let us compare the Giant TCR Composite frameset with Cannondale's CAAD12. Out of all the aluminum frames out there, the CAAD12 is probably the lightest made. A dip through the murky waters of the internet will give you the published weights of the CAAD12. For our reference, here are the weights:


  • Frame: 1098g
  • Fork: 300g
  • Hi-Mod Fork (for Dura Ace models): 280g

source: http://www.bikeradar.com/road/gear/category/bikes/road/product/review-cannondale-caad12-105-49861/


That is a scary 280 grams of fork there. It won't win bike of the year without rigorous testing from the designer and manufacturer side. Onward to the photos! Please take note that the small digital weighing scale may give inaccurate figures as I have no means to calibrate it.

The bearings at the bottom of the head tube are included here. Also included are the Dropouts, Braze-on clamps, and

Fork:

Seat Post:

The clamp part at the top of the post is very heavy. Probably comprising 80% of the weight. For the seat post, the weight is 250 grams.



Clamp:

The clamp weighs 24 grams


Other things that went with the frame:

Like I'm going to use that much spacers!


Recap for the Giant TCR Composite Frameset:

  • Frame: 1,187 g
  • Fork: 396 g
  • Seat Post: 250 g
  • Seat Post Collar: 24 g
Frame and Fork weighs 1,583 grams.
The entire thing totals to a weight of 1,857 grams.

I went to the LBS to have this weighed by a more accurate measuring tool.

For the entire thing, it said 1.92 kg. My digital scale is off by 63 grams! Maybe because of the loads of wax I put in before I went to the LBS. Nevermind the weight. As long as it is shiny!

2013 Giant TCR Composite Frameset

My latest secret acquisition is a 2013 Giant TCR Composite Frameset in White Purple Silver colors. I believe Giant made this line of frames until 2014. You will see no TCR Composites in 2015. Please don't tell my wife about this.

This bike sleeps on the bed.

This is going to be my first time to the Giant brand and carbon fiber composite material. I can't wait to have this weighed and built. I tried to compare this side by side to my Cannondale CAAD8 size 54 and they are basically the same size. The noticeable difference is that the seat tube angle of the TCR is way slanted to the back. The initial thought is that the TCR's geometry is more relaxed than the CAAD8.

I love the colors. Time to save up for those deep carbon wheels.

I love the way Giant played with the livery. This is what attracted me to this frameset. While the purple may not be desirable of most of cyclists out there, I think it goes well with white. It blends quite nicely as opposed to a strong blue (TCR Composite 1) that gives a more contrasting look. The absence of "Giant" brand name on every tube is also a big plus. I'd say this is subtle.

I took all these photos before my wife got home. Like those murderer masterminds you see in the movies, you had to plan where to hide the body before the police arrives. Our flat here is not really agriculture material with no nonsense rooms. I decided to hide it in the Balcony where she least visits.

That very same afternoon, for some inexplicable reason she went out there and decided to read her book. Probably the first time she did this. I just stood there at the adjacent room, looking through the window seeing her sitting down while the big bike frame is just behind her. She didn't notice, I thought to myself. The white paint of the wall matches the frame color very well and since the color scheme is not too contrasting, it basically hid itself as if it knew we were in this together.

Until now she doesn't know anything. But it is inevitable that she will know. Especially when my previous bike frame is Black!

Giant TCR Composite
Maybe knowing the size of my frame can help you visualize what I'm talking about.

I have to get this weighed at the shop tomorrow. Stay tuned. If only I know how to swap frames, then I could have done this by tonight. For now, my hunt begins for a bargain Pressfit bottom bracket.

The overall frame finish is generally smooth but not as smooth as I expected it to be, after all this is not Giant's highest end offering. There are some areas that is visually "turbulent" such as the seat stay bridge, connections within the main triangle, and the fork.

Internet literature around this frame only states that this is made from T-600 carbon fiber. No other details from Giant were presented and I can only speculate that this bike frame was built from standard modulus carbon fiber on everything. Since Giant makes carbon fiber composite bikes for major brands (Colnago being one of them. Source: http://www.canadiancyclist.com/races12/taiwan/parttwo/index.htm), can fairly say that they won't produce rubbish bikes.

Aside from the huge huge discount they offered me, the store where I got this gave me five years warranty. While this is a 2013 model bike, my warranty ends on 2021. How cool is that? Join me hand in hand as I gather strength to say this: I will not upgrade until then.
