A gram reduced here and there can accumulates to a KG if you are serious about itĀ
500-600grams reduction is already half a kilo..and that's big. I can't have the ultimate weight saving bike as I am running on Force groupset not the lightest Red.
I read that a carbon cockpit absorbs and provide more comfort on the road (irony that I chose an alu frame now) Safety wise I always have the feeling that carbon handelbar MAY break anytime when I am descending at 70kmh...lol..freak me out everytime just to think about it!
Now gatal2 to have another pair of wheelset..404 fc comes into mind but the need to change the brakepad and adjustment on the brakesĀ seems to put me off. What else is there that is hassle free but would be a significant upgrade over FR0?
of course reducing a bit here and there is going to accumulate up... that is basic maths... but, so does the money being spent... to reduce a kilo of a 10KG bike... easy peasy... but things starts to escalate once it reaches sub 8KG... reducing a kilo from there is going to be EPIC ENORMOUS AMOUNTS OF MONEY....i'd rather have a fat wallet and a fat bike than both thin ones...
Carbon construction on bars and posts as far as i understand is very straight forward... they don't lay different carbon material to change it's characteristics.... primarily because you can't suffer a broken bar while you might be able to risk a broken frame.. a bar that breaks mid ride is going to mean the rider hitting the deck like a sack of potatoes...
it's not like a frame where they might lay UHM carbon plies in certain parts and HM carbon plies or sometimes a sandwich of both in certain parts to make one stiff and one flex a little...even a pina 65hm1k does not mean the whole bike is made out of 65 ton per square centimeter high modules 1k weave plies... it just means majority of it is and some parts are made with lower modulus plies to make it dampen shocks and increase chance of fractures in the carbon plies...but, i'll give it to you that it is less buzzy on the carbon bars though... that is most likely possible...
furthermore, the carbon stuff nowadays are quite safe as long as you are not abusing it and only clamping down bolts with torque wrenches within manufacturer specs... only a big hit to the bar can cause seen or unseen fractures or cracks that might cause breakages when it is exercised during rides... i would say it is quite safe if you really take care of it like not letting the bike fall over and hit the group or knock it against things...i am a natural klutz which is why i stay away from it...
the only wheel that is capable of doing what you want would be the mavic cosmic slr and mavic rsys slr... both has the exalith aluminum rims and the rsys is almost as light as the 303FC tubulars and both are clinchers... the tub versions don't offer much weight savings.. pricey though...still has to adjust pads if you intend to swap wheel...
