Cynic Al, I do find you post basically assuming everyone is a numpty and new to bikes a bit tiresome, but thanks for your opinion. In my opinion I will be able to tell differences. I bought my scale based on back to back riding several similar bikes on the same demo loop at the same HR (tyres weren’t changed but I did have the same psi and they were all Ralph’s or Ron’s anyway).
I can tell the difference between my braccianos, rs21s and cosmics on the same bike with all the same kit. They all ride different and there is a noticeable difference in comfort, stiffness and speed.
With regards to the wheels I’m looking to test, it’s the top end mavics/fulcrum/zipp. Basically I want one set that are light for big climbing days, maybe a zero/sls/202 and one set for flatter faster days probably 404/c50.
Reading the reviews everyone has their opinion and rather than shelling out serious money without testing a product (would you recommend buying a bike without trying it?) I’d rather have a go in the real world on the real roads I ride,
Understand it would be expensive to do, but bike brands seem to do it, for similar priced products.
