fbmbmx Posted April 8, 2013 Report Share Posted April 8, 2013 Well I have noticed alot of people are really caught up on the weight of there bikes. My question is at a "normal" level of riding how important is it ? For example people are spending £120 on handlebars just to save 100grams. Would you notice the difference of 100 grams as a "normal" rider? Also say you'r bike was 9.9kg and you were used to riding it but then didn't ride for say a month and then rode the same geo bike which weighs 9.3kg would you notice the different and be able to do more? Would it effect you'r ability ? Harry Quote Link to comment Share on other sites More sharing options...
FamilyBiker Posted April 8, 2013 Report Share Posted April 8, 2013 i think a "training bike" should be heavier,to resist all the abuse,thats for normal riders too imo. my bike has 11,56kg,and thats more than light enough. if you ride comps,you´d get even higher when using a light bike,and youre used to the heavy one i think but i got no evidence and just one bike,so its just an opinion Quote Link to comment Share on other sites More sharing options...
trialsiain Posted April 8, 2013 Report Share Posted April 8, 2013 I just put metal bars on and a different front tyre which was 200g heavier and i didnt notice a difference at all Quote Link to comment Share on other sites More sharing options...
fbmbmx Posted April 8, 2013 Author Report Share Posted April 8, 2013 just the info i'm looking for. I think it is all big deal over nothing. Fair enough if you are in comps and then ever little helps like in motorbike racing when chasing hundredths of seconds! The things i think will make a difference is tyres and maybe rims as rotational mass is magnified hugely Quote Link to comment Share on other sites More sharing options...
Jake. Posted April 8, 2013 Report Share Posted April 8, 2013 I've got another bike now which is 11.5kg and my Limey is 8.7kg. Should make quite a bit of difference when I hop back on the limey once getting used to this GU. Quote Link to comment Share on other sites More sharing options...
matthew_coggan Posted April 8, 2013 Report Share Posted April 8, 2013 I just put lighter tyres, tubes, bars and pedals on mine saveing about 300g and it made a difference especally with the front end, but frame geo makes more difference.

FamilyBiker Posted April 8, 2013 Report Share Posted April 8, 2013 (edited) The things i think will make a difference is tyres and maybe rims as rotational mass is magnified hugely thats exaggerated in trials.youd hardly get noticeable centrifugal forces from riding trials i think. for example if your 24" rim and tyre,lets take the spokes out of the calculation,have 1kg.just hypothetic. youd have to get a rotating speed of 5 per second to get a resistance of 10kg angainst directional change. thats approx.35km/h i dont ride trials in such speeds lol Edited April 8, 2013 by FamilyBiker Quote Link to comment Share on other sites More sharing options...

But how much of that is "in you'r head" as you know it is lighter? is there proof in the riding?thats exaggerated in trials.youd hardly get noticeable centrifugal forces from riding trials i think. for example if your 24" rim and tyre,lets take the spokes out of the calculation,have 1kg.just hypothetic. youd have to get a rotating speed by 5 per second to get a resistance of 10kg angainst directional change. thats approx.35km/h i dont ride trials in such speeds lol thats exaggerated in trials.youd hardly get noticeable centrifugal forces from riding trials i think. for example if your 24" rim and tyre,lets take the spokes out of the calculation,have 1kg.just hypothetic. youd have to get a rotating speed by 5 per second to get a resistance of 10kg angainst directional change. thats approx.35km/h i dont ride trials in such speeds lol Yes I though that as soon as a posted but I think it may still come into effect a little with wheel acceleration (when kicking the pedals). I know it will be on a very very very small level but there would still be a bigger gain loosing 100g of you'r tires than say you'r bars ?

matthew_coggan Posted April 8, 2013 Report Share Posted April 8, 2013 Well some of it could be in the head, but the front especally felt lighter and I could do bigger stuff, so prob abit of both but if it improves your rideing thats what matters, you just have to say to yourself how much your willing to spend to save grams, as ability and practice is what matters to be honest.

Greetings Posted April 8, 2013 Report Share Posted April 8, 2013 Also say you'r bike was 9.9kg and you were used to riding it but then didn't ride for say a month and then rode the same geo bike which weighs 9.3kg would you notice the different and be able to do more? Would it effect you'r ability ? In my case, reducing weight from 10.5 to around 8.8 over a period of a few months improved my riding during the first ride after saving weight. Then it no longer benefited my riding since I was probably subconsciously using less strength during moves rather than going higher. So to answer your question - no, I don't think it will benefit you. You will notice a difference on natural though because you'll be able to ride for longer. 1 Quote Link to comment Share on other sites More sharing options...
Azarathal Posted April 9, 2013 Report Share Posted April 9, 2013 I barely notices changes that much, didn't notice any difference in feel between sl forks and trialtech, nor between changing my kenda kinetics (1150g each) to my fat Albert rear (600ish) and small block front (500ish). I don't even notice any difference between adding a few stem stackers at all Quote Link to comment Share on other sites More sharing options...
AkuskaUK Posted April 9, 2013 Report Share Posted April 9, 2013 I've always thought of it as more of a bragging tool... "My bike is lighter than yours so it's better". Some people are like that and some are not. Quote Link to comment Share on other sites More sharing options...
315r Posted April 9, 2013 Report Share Posted April 9, 2013 The most important thing to save weigh is to not tire you at long sections at competitions. obviously, in a normal riding, one kilogram above or below don't make difference. You provably can feel it, but not improve your riding 1 Quote Link to comment Share on other sites More sharing options...
