Would you really feel the weight difference between...

a Kuota kharma and say a planet X sl pro carbon?
I think the frame weights on meduim frames are 1260 Vs 1120, making a difference of 140g's.
I've never really ridden road bikes before so I dont know how to pedict the difference in performance. I mean, I doi have asperations of doing some really long rides but I'm no pro or anything.
I really like the look of the Kharma, but made a 'looks' mistake with my mountin bike and dont want to make the same mistake again!
What do you think lads?

I'm always reminded of the Robert Millar maxim, "it's a lot easier to lose a pound off you than it is off the bike".
I doubt you'd notice any difference between those two. With the money you've saved on the Planet-X you could invest that in lighter components.0 -
Hahaha Yeah I like that quote :P
Although I think the Kharma is slighty more expense so i'd be paying abit more for the heavier one :?There is nothing more unequal, than the equal treatment of unequals!0 -
A full water bottle weighs 500 grams: based on the way my bike 'feels', I have absolutely no idea whether my water bottles are empty or full, when I'm riding. In my case, that is an undetectable frame weight variation of 1kg range.
Maybe I'm an insensitive lug, but I suspect there are a few princesses troubled by peas in cycing.0 -
Cool - I just read a review where it was good but they called it a bit of a 'porker'. I think I'm happy to take a wizz before I go out and cancle out the difference

Careful, you'll trigger the "love / hate" Planet X debate that rages like wildfire every few days. I've got a Planet X titanium Pro Road, and my son has an SL Pro Carbon. We're both very happy with them. As balthazar says, most people would't bat an eyelid at adding a full water bottle or two to their bike without complaining about the feel. There's a good chance that if you're asking this question, you'd be just as happy with the PX as you would the Kharma - but you may find one far more attractive than the other, which might tip the balance."The only absolute statement is that everything is relative" - anon0

Oh I know... I had a few beers before daring to whisper the name "Planet X" on here hahaa
But the plot thikens slightly, apparently its not the frame that adds the weight but the components compared to other bikes in the Karmhas price range. Apparently a 4lb difference which sounds more substancial:

To be onest I do fancy a "*P@#£T X", for the price, but then liked the look of the Kharma...
Hmmmm?!There is nothing more unequal, than the equal treatment of unequals!0 -
Hey, does anyone know the lightest bike in the £1K ish price range?There is nothing more unequal, than the equal treatment of unequals!0

the Boardman Team Carbon must be up there
For bang-for-buck (love those yanks 8) ) it's up there with the P-X. The P-X probably gets the nod for spec due to the 6700 Ultegra gruppo.Facts are meaningless, you can use facts to prove anything that's remotely true! - Homer0 -
Its going to happen isnt it... All answers seem to point to the planet! There is nothing more unequal, than the equal treatment of unequals!0

A bit more than £1K but a pinch lighter than the Boardman, the Radon RCS 5.0.tonyeynon wrote:Hey, does anyone know the lightest bike in the £1K ish price range?
Carbon Monocoque with Ultegra and Shimano WH-RS10 wheels, 7.8 kg without pedals, about £1150 plus £50 shipping charge.0 -
Can you get the Radons in the UK?0

I have the Kharma - I went for the bling over the weight saving - that I could have got on the boardman, or planet x. As todays bikes go the kharma is quite heavy. .....But guess what it doesn't feel heavy at all, I can't imagine a bike being much lighter than my kharma.
I have heard suggested that frame weight is an overated stat - and that things like wheel weight have more bearing on performance. Me ? - I have a bit more weight around my middle to shift, before I worry about 500g on the frame !0 -

Hmmmm?!
Not just saying this because I have the kuota - but that review is highly suspect. I trawled the web and the same magazine - describes the kuota kebel as 'super light' - in fact its only 50g lighter than the kharma. Dig a little more and you will find the boardman weight quoted heavier than in that review.
I disagree totally with the conclusions of that review - in my experience the Kharma climbs a treat - if it has a weakness - it isn't that stiff in comparison to my alu pinarello - however my average speeds are better on the kuota, and I enjoy riding it more. a few tips to pass on
Mine is a 2009 kharma, I upgraded to 2009 ultegra for only an extra £90
The continental sports tyres that come with kharma, aren't great - try and get a good price of pro race 3's or attaks - this really made a difference to performance of the bike
if you want the reduced weight and stiffness - the kebel probably won't cost much more - if anything !
I spent a while, asking shops for best deals on kuota's -PM me if you want details of the shops that offered me good deals0 -

You're right. Frame weight is an overrated stat. People make far too much of it when most of us (myself included) have a bit of a spare tyre anyway
One bike might be 1kg lighter but a rider will only have to ride about 1% harder (not too difficult). The question we then have to ask is whether we can really quantify feeling 1% more knackered at the end of a ride/race.
As far as I can see the same goes for wheel weight too. I read somewhere (by a wheel manufacturer oddly enough :roll: ) that wheel weight/inertia counts for twice the weight of the frame/forks/bars. Complete bollox I'm afraid (the torque needed to overcome wheel inertia counts for about 1% of the total torque needed to accelerate a bike).0 -
Re: the bike I'd go for the Kharma.
I've now seen both in the flesh and whilst the PX is nice the Kharma in my LBS looks abolutely stunning.0 -
That's an allusion to one of the more long-lived cycling myths. A pound off the wheels is worth two off the frame... etc.kingrollo wrote:I have heard suggested that frame weight is an overated stat - and that things like wheel weight have more bearing on performance.
You can prove to yourself how little effort it takes to accelerate wheels, by spinning them in your hand. Next time you take a wheel off your bike, spin it as fast as you can with your thumbs. Thats 0-20 mph (ish) in about 1 second, far faster than you'll ever accelerate pedalling your bike. And you did it with your thumbs. Now imagine how little resistance this presents to your two legs.0 -
Never buy a bike by it's weight. Choose by quality and the way it makes you feel - cycling is a tactile and aesthetic experience - not a numbers game.0

On the kouta website the kharma in the mainly white paint job with naked carbon and red highlights is stunning. I've never seen it like taht in the shops and didn't even realise you could get it in other paint jobs. I may have got the kharma if i'd seen it like hat at he bike shop i went to, but they never even mentioned it was available like that!?!Bianchi. There are no alternatives only compromises!
I RIDE A KONA CADABRA -would you like to come and have a play with my magic link?0 -

its a new paint job for 2010 - agree it looks the part though0 -
Just realised that since I last rode "properly" I'm carrying an extra 56 pounds in body weight. My bike is an old steel 653 frame and heavy by todays standards at around 22lb so I'm actually carrying the equivalent of 2.5 fully laden bikes around my stomach. With that in mind I don't think a couple of hundred grammes on a frame weight won't make any difference! 0
