I finalized a deal for a 2nd hand said to be seldom used Mosso Super Lite Alum Bike with 105 5800 group set, with RS 10 Shimano wheelset. It was revenge deal that I pushed through after the seller of a carbon fiber bike balked on giving a warranty on the carbon fiber integrity (who wont ask for the warranty knowing that carbon fiber has inherent weakness especially if second hand, is old and used hard. The bike was owned by who used to be member of racing club in North America) So it was botched and ditched. It was a P44,000 deal for a bike that was supposed to be 7 kg in weight. (The frame set should be 900 grams)
Fortunately I saw this Mosso bike being sold by by the RBP group for a cousin.
And saw finally got the bike and tried to compute for its weight. For a P26,000 deal,this was what I got:
Frame - Alum 705, ARC 710 Mosso - 1520 grams
Alum Fork 700 grams
STI 105 5800 group set 2549 grams
Seat post Truvativ 325 grams
Seat 300 grams
Wheelset RS 10 1845 grams
Tires Maxxis 200 grams
Drop bar Laplace 290 grams
Stem Laplace 130 grams
Pedal 105 carbon 240 grams
Total weight 8,099 grams
x 2.2 lbs/kg 17.81 lbs
1. This is a light bike considering that most carbon fiber bikes are 16 to 17 lbs. Compared to my botched cf deal, the price difference of P18,000 was for a mere 1.099 kgs or 2.2 lbs or P16.37/ grams
2. In the UK Cycling Magazine there was comparison of Italian bikes features, weight and price:
Colnago CLX Ultegra 7.96 kgs 17.51 lbs 2,799 UK pounds
Pinarello FP Quattro 8.36 kgs 18.39 lbs 2,869 UK pounds
Bianchi Infinito 7.43 kgs 16.346 2,200 UK pounds
Basso Laguna 7.88 kgs 17.336 2,599 UK pounds
Cinelli Saetta 8.20 kgs 18.04 2.579 UK pounds
That carbons might is light is not true here. The Mosso bike is lighter than Pinarello and Cinelli
3. It was suggested that to lighten the bike, I should buy a Fulcrum 7 wheelset. The seller said that he uses a Fulcrum 7 which seemed to be 2 kgs lighter. But the facts do not agree with his claim. Both tip the scales at 1845 grams
4. The opportunity for me to lighten the bike would be to get a carbon fiber fork which should tip the scales at 300 grams:
Opportunities for weight savings
Current weight of alum fork 700 grams less 400 grams if carbon 300 grams lighter
Cost about P3,000
Shimano Group set upgrade 2,549 less 2,445 of Ultegra 104 grams lighter
to Ultegra P15,000
Weight savings 404 grams
Estimated weight of Mosso with the upgrade 7,695 grams
8099 - 404 grams
16.929 lbs
How about Wheelse? An upgrade of about P50,000 would save only 300 grams
Fulcrum 7 weighs 1.8 same as Shimano RS 10 Same for Fulcrum Quattro
Vision Wheelset would weigh as much and cost P18,000
So maybe if I buy a new carbon fiber fork, I would save about 300 grams.
As of now, I have light bike. I am not 40 kph rider and spending more than P50,000 would not make me a faster rider. With the Fuji Carbon bike, I am not a faster rider.
