frames are lighter than carbon.
Parts that make most impact on weight;
After being in the bikers world for more than a decade, more or less I now know how to have a lighter bike. Some measures are cost effective. Some are not. The biggest weight contributors, they more or less make up 25% of the bike weight are:
1. Frame and fork - from 1.5 kg to 2.5 kg
2. Group set: from 2.00 to 3 kg
3. Wheel set from 1.3 to 2 kg+
With regards to other parts: stem, head set, bars, gains can be minimal. So for you to aspire for lighter bike, think again....
1. Frame and fork:
Alum frame + alum fork 1.4 kg say Mosso and fork .5 = 1.9 kg
Alum frame + carbon fork 1.4 kg say Mosso and carbon fork .4 = 1.8 kg
1.1 kg say CAD 12 and carbon fork .280 = 1.380 kg
With the new CAAD12, Cannondale seems to be throwing down the gauntlet to the competition in high-grade alloy. The numbers are compelling: the frame weighs just 1098g, which is 52g lighter than the CAAD10, while the fork – based on Cannondale's new EVO design – weighs a mere 300g. More expensive CAAD12 models get the HM fork, a scarily light 280g.
Carbon frame + carbon fork 1.1 kg + .4 kg = 1.5 kg
Superlite carbon frame + carbon fork 900 gms. + 400 kg = 1.3 kg
Take note:
1. That carbon is not necessarily lighter or sturdier; some alum are lighter than carbon and lasts longer and dont disintegrate on impact. Such is the strength of brands like Cannondale. Alum frame that is lighter than carbon
2. Carbon fork gain is limited to only 100 grams. It has something to do with the steerer
2. Wheel set:
Generic wheel set local - 2.2 kg
RS 10 - 1.845
RS 11 - 1.750
Fulcrum 7 - 1.845
Fulcrum Quattro 350 mm - 1,700
Zipp - 1,300
Campagnolo Bora 2 - 1,300
1. Most of the entry level wheel set are from 1.8 kg to 2.2 kg. The 1.5 kg weight is in the territory of carbon fiber.
2. Sometimes the wheel sets are heavier for being aero say 500 mm. But experts say that at 35 to 40 kph aero counts. Being slick can save you up to 50 watts of power and that means a lot in racing. Weight give you momentum and inertia to move forward. For a 200 grams difference the price difference is staggering P30 up to 150t. Only millionaires and riders with sponsors can afford it.
3. Group sets:
at mere 2,000 grams same as Campy Rekord and SRAM red
The lightest group sets are SRAM red, Campagnolo Rekord and Durace. Around 2.000 kg total weight
SRAM and Campy would cost just about even P120 to P130t (may nagbebenta sa Toyota Shaw P80t only paluugi) at sa Sabak P30t only for SRAM red)
Ultegra 6800 and 8000 weigh about 2,550 grams, 6800 is sells for P17 k, 8000 for P30k
Shimano 105 is 2,700 grams is availablefor P13,000 only. For 4,000 difference the difference in weight is 200 grams. Ultegra 6800 is value for money and is slightly lighter than 8000 GS.
The value for money:
1. Cannondale frame say CAAD 10 to 12 with carbon frame
2. GS Ultegra 6800
3. Wheelset - fulcrum quattro (lalabas daw si Christy ng tig P15,000 soon)
2. Analysis of weight of my Current bikes:
Estimated weight:
1. Fuji SL 10 super light:
Frame - 700 grams
Carbon Fork - 400 grams
Campy GS 2,000 grams
Cosmic Wheelset 1,400 grams
ITM drop bar 400 grams
Ritchey Seat post cf 300 grams
Selle Italia saddle 300 grams
Exustar cf pedals 88 grams
ITM stem cf 200 grams
Conti Tires 500 grams
TOTAL 6,288 grams = 13.833 lbs
Estimated price P200,000+
2. Mosso 710 Alum bike with 105 group set:
Frame - 1,400 grams
Fork 500 grams
105 GS 2,750 grams
Wheel set RS 10 1,845 grams
Truvativ seat post 400 grams
Leopard saddle 500 grams
Laplace drop bar 400 grams
Laplace stem 350 grams
105 pedals 300 grams
Maxxis tires 600 grams
TOTAL 9,045 grams = 19.899 lbs almost 20 lbs
lighter than most bikes which weight 23 lbs
As you can see, there will be difficulty in upgrading the bike
3. Freccia Celeste (Current weight)
Frame 1,234 grams
Carbon fork 400 grams
Wheel set generic 2,000 grams
Ultegra 6600 2,800 grams
Saddle Selle 300 grams
ABR stem 400 grams
Alum Seat post 400 grams
Alum drop bar 350 grams
Pedal exustar 400 grams
Conti tires 500 grams
TOTAL 8,784 grams = 19.324
Planned upgrade for Freccia Celeste
Drop bar Toseek 230 grams (-120 grams)
Stem CF 200 grams (-200 grans)
Quatrro Wheelset 1,700 grams (-300 grams)
CF seat post 200 grams (-200 grams)
WEIGHT SAVINGS (-820 grams)
Net weight 7.964 grams 17,520
If we buy Ultegra 6800 less 100 grams
Net weight 7,864 = 17,300.
Buying a 1,500 grams wheel set will save another 200 grams but will set us back by say 23,000 php
Total expenses for upgrade:
Toseek cf parts - 3,500
Wheelset 15,000
Repaint + decals 2,000
Total 20,500/800 grams savings = 25,00/gram
More weight savings:
Upgrade to 6,800
From 2,800 grams to only 2,557 grams 243 grams at cost of P17,000/243 = P69.95/gram
7,864 - 243 = 7,621 grams = 16,766 lbs
I can even make the bike lighter by buying a Campagnolo Bora 2 carbon wheelset P23,000
Weight 1,300 grams - savings vs Quattro - 400 grams
7,864 - 400 grams = 7,464 grams = 16.420.00 lbs
Cost/gram saved = P57.50
Great option:
Toseek parts 4,200.
Bora Wheelset 23,000
Repaint 2,200
No more quattro upgrade
7,964 grams - 400 grams = 7,564 grams x 2.2 16,640
Of course, light bikes do not make you a fast biker, a fast biker makes the light bikes go faster.
Upgrade your bike, upgrade your ride too -practice sprint, TT, fast pedaling, developing strength by going uphill on heavy gears. Race at times with colleague. Practice long rides, bust your lungs from time to time, race with kapadyak. The more you will be proud of your bike, and enjoy your passion
