Road Bike Weights

[ti guy]

What is considered a "light" road bike in both carbon and ally.. what is average and what is considered too heavy..? any thoughts on this?

 

or maybe i should be asking is 8.4kg too heavy for an ally bike?

 

AX Lightness frame and parts, Campy Super Record drivetrain + Pedals = 5.2kg

Cannondale Supersix Evo Ultimate.

 

AT just 695g for the frame, 1g lighter than Cervelo's new RC5A, coincidence? I think not.

 

Anyhow, this bike weighs in at 4.9kg assembled.

 

It comes with 2 spiders, one 110bcd and one 130bcd as the bike comes standard with a compact crank to save weight.

 

 

 

The only downside is that it costs R112 000

My new favourite bike. I wonder what my missus will think if I sell my car and get one.

Go for it!

 

Alternatively, you could get the RC5A, also very light.

 

Theres one at John O'Connor Cycles if you're interested.

R170k.

 

But the Cannondale will always be best!

ALWAYS.

Use psychology. Ride a good old farmgate. If you do badly in a race, you can blame the bike; if you do well, you can say it's despite the bike.

Pretty sure i'm right in that the lightest "racing" bike needs to be 6.8kg according to UCI rules. Just use that as the guideline against your measurement. If ur bike is 8kg, its cheaper to drop the body weight, more fun and i guess the morally correct thing to do? Other just pay it away.... not going to help on the big climbs if your bike weighs 8kg or 5kg... rather train harder and drop the weight!!!

Morally correct? WTF has morals got to do with the price and weight of your bike?

But the lighter the bikes they higher-end they are, the stiffer they are which results in a better power output/power loss ratio = faster climbing, so like uhh?

Wheels and drivetrain are where it matters most imho. Your bike can be too light, especially riding into windy conditions. I rode in a DC tandem team recently where there was a tandem that weighed just over 11Kg (unbelievable but true), and they used a lot of energy to keep up on downhills and into the wind.

Quite a few of the PRO riders bikes are under 6.8kg's and the mechanics add some weight to the bikes.

JA/nee imagine that.. let's gooi a powermeter on there to make it legal... hence some pros riding alu bars

Hence all cannondale team riders' bikes come equipped with a powermeter and a piece of lead dropped into the seat tube.

Can that perhaps be an urban road legend?

Too many people focus on bike weight and not overall weight. I bet very few people know the weight of their shoes or helmet - both of which can cut 100g without laying out too much moola.

 

Likewise round the waist - in many cases the easiest way to lose overall weight.

 

That said - a superlight bike has diddly squat to do with how fast you are - if you love weight weenie bikes and can afford exotica it's perfectly acceptable.

is that really true, surely the cross section has way more to do with it than a few kgs here and there.

 

i wouldn't know myself, i have four bikes and heaviest one is actually the roadbike(13kg ocr3 - there's nothing wrong with sora, baby)

No, that is not an urban legend, but the weights are not £dropped" into the seat tube. They actually fit into the feame. Different weights for different wheelsets to always have the bike exactly 6,8kg
