I did weigh my canyon, the scales do work and its 20.5lbs with pedals.
Its the bottom of the range Canyon carbon and i have put on another wheelset roval carbon rims with AM classic hubs with XX cassette, changed brakes to some old formula R1 ones i had and swapped the the bars to a ritchey 620mm superlogic 10 degree, Esi Grips and a Cobalt carbon seatpost and selle italia slr 145 saddle.
To lose 1.5lbs in the Autumn i am putting on new cranks instead of the X9, will save approx 250gms there. Lose the front shifter and front mech around 240gms, maybe if i can get rid of the fork matchmaker lockout about 50gms and the stock chain is heavy so that will be replaced when it wears in the next 3 – 4 months
Also change tyres, will save around 150 – 200 gms changing from current set up to specialised storm or Rocket rons if racing. That Rubena Kartos on the front tyre is far from light. Also nearly forgot i need to add the weight of a chain guide at about 50gms..
