I have not used my Venge Vias S works bike shod with Cosmic wheel set Kenda tires, SRAM red groupset (which is light) for a while More than a year Because 1. The bike is not that strong it feels
vague compared to Shimno brakes (VV has built in V brakes) 2. There is a clanking noise at the rear chain stay which is rather annoying. I bought this bike from a Globe Electronic Engineer from Batangas who used the money to buy a Bianchi Nakatawad ng mga P12,000 sa original buying price niya sa BN. Now I know why. he disposed. it. Because of the internal brake cables at the handlebar and steerer, the cables are likely to get kinks and not function well.... He was obviously troubled by the braking efficiency.... The external bikes and external cabling works better.
When the bike news featured again the bike of Peter Sagan, a Venge S works, I decided I must bring out my S works again. First I had to do something with the brakes Many mechanics from the area, including the Cainta area. Some hope from #Dante of Lifecycle at Greenhills, Mechanics of Jay Gotangco at Calumpang, and Jun of Christy's.
As stop gap measures:
1. I adjusted the front brake adjustment so that the pads are closer. It worked. Lumakas na preno. Sa
rear, hinatak ko ang cable much tighter para mas dikit ang pads to brake line. It worked too. Maybe
the brake efficiency is now 75% instead of 50% before.
2. As for the unwanted sound at the rear stays:
1. I cut a plastic tube about 3/8 in diameter 2 inches long into two wrappped the RD cable entry into the rear stay so that it is not loose;
2. From the BB side, I cut a length of the same plastic tube wrapped the metal spaghetti cable of teh
RD cable so that the clanking against the tube could be dampened. Nabawasan na kalampag.
So you see, you do not have to bring all your problems to the mechanic or hope for a high cost solution like bringing the bike to Missing Link or Bikezilla (where the repairs may cost me a thousand)
I am happy now with my S works bike. Naitravel ko na nang Morong. Maasahan na

Many are now carbon fiber basher because of Geraint Thomas crash at Tour de France

Geraint Thomas defending champion crashes
G. Thomas bike breaks as he lands on another biker
From Cycling weekly
Many saw the picture of Pinarello Dogma f10 which broke into two at Stage 8 of Tour de France. Geraint Thomas quickly remounted and joined the Peloton. and the accident did not cause any change in the GC
classification of Thomas the defending champion.
Now there are many controversies and speculations regarding the accident and carbon fiber (in particular)
1. That the race directors car ran over the bike? (This is incorrect look at the picture)
2. That the Pinarello frameset is made in China.
3. That in general, for most bikers, Carbon fiber is not a nice material and subject to breakage and frequent purchase.
Now let me advance some of my comments:
1. Carbon fiber is a very strong material 3x stronger than stelel and 3x lighter. However high modulus bikes stiffer bikes are easily subject to breakage especially if subjected to strong impact. On the other hand, this behavior of the material absorbs most of the impact, saving the biker rider from injuries and/or tauma.
2. The advantages of carbon fiber:
1. Light (saves on watts of the rider)
2. Can be made more aero dynamic (saves on watts too); can easily be shaped and moulded
as they are manfacured
3. Is more attractive being made of modern, space age materials like space craft, air craft, formula
cars,..
3. In the race, generally the lighter carbon fiber bikes have less material (and consequently more prone
to breakage) HM carbon fiber means they are brittle. Pinarello uses 1100 toray, one of the highest
rating and we can conclude that it is more brittle, but stronger with lesser materials...
4. If a car ran over this about 3,000 to 4,000 lbs and may be at moderate speed, then naturally, the
bike frame would break.
You may have your opinions about the carbon fiber built bikes but the ones I had: a Fuji SL 10 (5 years), a Pinarello F10 (1.5 years), and S Works Venge Vias (2 years old) are still well built and strong. Go ahead with your comments. but may be you cant afford to have one...And the comments may be just sour graping... He
