NotSoBigBen Posted January 28, 2016 Posted January 28, 2016 Unless one is damn close to the front and those few seconds (or could it be minutes ) you may gain from having a lighter bike is the difference between winning or even 'placing' does it make sense to worry about it? * OP it is an interesting topic though - carbon vs alu weight!
Christie Posted January 28, 2016 Posted January 28, 2016 Also consider that with MTB riding there is a lot of acceleration, deceleration and direction changing which are all negatively affected by weight. This translates to additional energy consumption and rider fatigue, but to quantify bike weight and/or wheel weight inertia is beyond my capabilities. So, suffice to say that lighter is better and weight saving on rotational mass is even better, and that is as scientific as I can get But here we are excluding wheels and crank, so no rotating weight , just weight. I suspect on a moderate rolling route with no mountains, like Crater cruise or Pretoria east, 2kg extra wont make much difference. Up the Mamba in Sabie it might, Im just wondering how much. Lets say it is 5 min over 70km - is that worth spending R30 000 for?
Halfdoesyn Posted January 28, 2016 Posted January 28, 2016 It's all about diminishing returns. At the top end of the price scale, you get just a little more (less weight) for a lot more money, where the inverse is true at the bottom end. Find the price/product trade-off that compliments your skill/fitness/application level. But then again, we sometimes buy with our hearts and leave our pro/con list at the shop door...
s14phoenix Posted January 28, 2016 Posted January 28, 2016 I think the OP needs to take a nice picture of his bike so we can look at it. maybe there is something he can do to drop weight for not a lot of money at all...
xnadu Posted January 28, 2016 Posted January 28, 2016 I wont spend R's to get a lighter bike i enjoy just fun ride and im not in the race to win it only to enjoy it as long my bike dont weigh more then 20kg then im happy
Edge_Design Posted January 28, 2016 Posted January 28, 2016 A HT frame is about 10% of the total weight of your bike so changing that is just one small factor in the total weight - your tyres probably weigh more than your frame as an example. Knocking a kg off the current weight will only impact the number of likes you get on a thread like this - it will have little or no impact on your riding enjoyment.
rock Posted January 28, 2016 Posted January 28, 2016 Tyres (as a pair) are the heaviest component of your bike besides the frame/fork. strip your bike, weigh each part on a proper scale and you will be surprised where their is extra weight, especially on 'short cut' cheap OEM parts. Then you can identify he best bang for buck parts to start with to drop weight. Its nice to have a light bike. Regardless if you can lose 2kg on your body. Losing 2kg on your bike is more fun.

There fixed it and I can't see a problem with that if you can afford it?
Bomberman Posted January 28, 2016 Posted January 28, 2016 Easy...Take some sand paper, and sand down the paint on your fork.
arendoog Posted January 28, 2016 Posted January 28, 2016 The best-est strongest carbon can be used to build the lightest frames and not jeopardize strength .Frames like Santa cruz and the like .But those frames are double the price of ordinary carbon .KTM is a standard carbon frame and will be slightly heavier ,so is most of the affordable carbon frames .Then you add all the expensive light gear and you can get a XXL HT frame with Fox kashima and XX 2 x 10 down to 10,5kg .Cost R42000 2 years ago .KTM probably half the price but will last longer and is 1kg heavier
Andro Posted January 28, 2016 Posted January 28, 2016 I have build quite a few bikes. and get questioned about; light vs heavy and cheap vs expensive. My experience is that when building a bike under 9kg for every 100grams = R1000 out of pocket. A lighter bike is therefor more expensive with more expensive parts meaning the shifting ect is smoother = beter ride experience. A person always believe that they have the best car/bike/cycle.... just because they havent driven/rode or dont know of beter. But all and all its also what you willing to fork out and how crazy or passionate you are. Here Im thankfull for Bikehub Classifieds..
DoubleJ Posted January 28, 2016 Author Posted January 28, 2016 My riding ability does not warrant a R40 000 sub 10kg bike. My big worry was the fact that the scale doesn't tell the same story as the specsheet weight number. But I'm very happy with the responses you guys have given thank you. Bike rides like a dream....its even climbing faster the more I train (weird nê)
DoubleJ Posted January 28, 2016 Author Posted January 28, 2016 I've in the meantime added a KCNC 60mm stem and 2 tubeless Maxxis icons. Unfortunately the picture uploaded sideways.
Larry King Posted January 28, 2016 Posted January 28, 2016 Easy...Take some sand paper, and sand down the paint on your fork. whaahahahahahhaha, remember how that was a trend for a while..
Larry King Posted January 28, 2016 Posted January 28, 2016 I've in the meantime added a KCNC 60mm stem and 2 tubeless Maxxis icons. Unfortunately the picture uploaded sideways.Those tyres are dog heavy, what do you weigh?
Andro Posted January 29, 2016 Posted January 29, 2016 do some homework - upgrade as you go. as you have some funds or as parts needs replacement. if you use shimano upgrade to XT - slightly heavier than XTR but more affordable without losing any or very litte performance/weight. Sram... Upgrade to XO - orther than XX...
