To Upgrade or Not to upgrade ?

The Question is: Wheels how much will I benefit from an extra R5000 "investment" in lighter more Aero Wheels?

 

Ok let’s start with my current stats

9.5 kg Bike Total Weight

92kg Rider (and full of muscle .. well mostly)

 

Wheels Tires Tubes and Cassette come in at 3.1 kg

Roughly 2.1kg’s of which is the Wheels

900g Front Wheel

1100g Rear Wheel

700g Tires

250g Cassette

150g Tubes I guess

 

For roughly R4000 I can get a Slightly Aero 30mm deep wheel at 1560g for the set.

anyone care to share the benefits of the light rims ? what kind of difference can one expect from the 500g less weight ?

Also got my eye on race tires at 350g for the pair J

Total cost R5000 = Weight saving of 850g

or is that a waste of money ?

 

Hello Juddy.

 

Firstly its your money, and how you spend it, you must be happy with.

 

Having said that, some of these posts are really humourous.

 

Cycling is about specific power or power to weight ratio.

 

Lets say you produce 300W of (average) power (example average rider)

 

power 300 W and riding weight 101.5 Kg = 2.95 W/Kg (the higher the number, the better)

 

you want to save 500gm ?

 

power 300 W and riding weight 101 Kg = 2.97 W/Kg the higher the number, the better

less than 1% improvement

 

My suggestion, lose 10 Kg ....

 

power 300 W and riding weight 91.5 Kg = 3.27 W/Kg the higher the number, the better

this is 11% improvement.
