I'd like to share this discussion I found on the net. Don't get me wrong, I'm not implying which one is better as I have both alu and carbon bike (honestly I can't feel much differences between them). Some of the replies had a good and valid points. Perhaps it can help those beginners out there who are seeking their first road bike and unsure between alu or carbon frame.Â
ahh there's many more in that discussion..you can read more here:
http://forums.roadbikereview.com/bikes-fra...-do-276830.htmlMy take? Whatever it is, just get the first roadbike new. Be it alu or carbon or bamboo or whatever.
i do agree with you on the first bike... if you have money like our taiko here... get a carbon.. else stick with a cheap bike as i always refer to the first bike as an experimental bike where you find your feet and learn things about the bike and develop your set of criteria for a perfect bike for yourself... not always the greatest is the best... if you don't feel right sitting on a great bike, you don't feel the best...
secondly, the argument would be quite complicated without taking into account on entry level and high end ones from both ends of the frame material... of course, some high end aluminum frames might be as good as entry or even mid range carbon hence not feeling much difference (not saying your mirinda sucks lar, but you understand what you get for RM7k right)
but with carbon, you get better lifespan off the frame (with the exception of crash damages), lighter weight, better stiffness, vertical compliance if designed properly...the list is endless.. all that comes with none other the less, a hefty price....with new development in carbon layup schedules, pre-preg carbon cloth or custom weaved carbon tubes like Time or BMC, top secret epoxy resins, internal ribbing, again top secret carbon curing time and shit like that.. they will continue babbling bullshit into your ears until the nasa composites expert loses their jobs...
carbon in bicycle building is still way off from industries like aerospace and formula 1... hence, which is why specialize went to mclaren to allow them to analyze their carbon layups with their FEA softwares and Cervelo has Don Guichard to head their technologies and development department...
even the carbon cloth that is used in bicycle industries is still some way off the ones used in aerospace and formula 1... those are closely guarded secrets still and it is most prolly to costly to use for production...
aluminum would be the defacto standard in cheap bikes as it is cheap and workmanship is lesser...and a more reliable material to build bikes around despite some less interesting characteristics...if not, our cars would all be made from carbon by now...

give me your email address. i'll send you the flyer. it's 350, not 300. sorry.
but you need to have a bike first, i think.
ei....no side income... need i remind you of company policies?

u need to go back to the engineering aspect la. alu has definite fatigue lifespan. not with carbon. carbon has no fatigue life. coz fatigue can be calculated only on metal material. but that doesn't mean carbon is better. carbon quality depends on who manufactures them and the grade of carbon cloth and resin, etc. that argument about aluminum engine and aircraft is complete BS. the kind of loads applied onto a bicycle frame and onto aircraft and engine block are completely different. even the purpose also different.
promo for our shop la. but nobody interested. malaysians rich i guess, don't want free stuff.
the use of aluminum in cars like engine blocks and radiators are different... those components are not subjected to torsional stresses... if they put it into areas like suspension linkages and arms, then those might start to show signs of fatigue as compared to conventional heavier steel parts...
there is also a higher chance that we feel fatigue in parts like our frames because it is responsible for transferring our power output and more importantly, power that we generate...we don't feel the effects of power being sapped from the car because we are only stepping on the gas pedal and the relation and linkage from the pedal to how well power is being transferred is not there as compared to the bike...
they are afraid that you have smelly armpits...
