If you're like myself and are cautious about the weight of your bike, then one of the brakes which should be high on your to buy list have got to be a set of Formulas!

Well we figured the one listed weight of 277grams for the Formula brakes is all great to know but in a real world setup you might want some more information well that's what I've been doing today.The listed weight of 277grams is for a front 160mm post mount brake setup i.e. a front brake, rotor and bolts and the two bolts to mount your brake to your post mount forks (i.e. just 2 bolts). But what if you want to have 180mm rotors and the relative mounts, or if you want to upgrade your brakes with IRA/FSC.

First up here are the weights of THE ONE's and R1's front and rear (no bolts/kits etc).

THE ONE front:

THE ONE rear (226g):
R1 front (180g):
R1 rear (194g):
Now I bet one of the main things putting you off getting your brakes upgraded with IRA (instant reach adjust) and FCS (feeling control system) is the worry of extra weight. Well I took the hassle of weighing our already customised R1?s and THE ONE?s for you and they weigh a whole 15g extra per brake (approx): THE ONE front (224g):
THE ONE rear (240g):
R1 front (196g):
R1 rear (208g):
Obviously this isn't quite a scientific investigation as these are all different brake systems I've not gone through the trouble of using the same brakes and changing them as I'm going along so when you buy your own set the weight might indeed be different. Now you might want to be purchasing some upgrades for your brakes to make them that little bit lighter, these being Carbon levers and Aluminium rotor bolts? guess what I weighed them too! Steel Rotor Bolts (10g):
Titanium Rotor Bolts (6g):
Aluminium Lever Blade (18g):
Carbon Lever Blade (8g): So these are the individual weights I thought I?d save some effort with the maths and do some weigh ins of some standard builds for front and rear: R1 Front with 180mm rotor and HW kit (362g):
R1 Front with 180mm rotor and HW kit with Titanium bolts (340g):
R1 Rear with 160mm rotor no hardware kit as most race bikes have post mount (304g):
R1 Rear with 160mm rotor no hardware kit with Titanium bolts (294g):
So the lightest possible break setup you could have with 180mm and 160mm rotors front and rear is 340g (for the rear) + 294g (for the front) minus 20g for upgrading to carbon levers (8g meaning 10g lighter per lever) gives a whole build of 614g which will be lighter again if you were to put 160mm rotors on the front and obviously you'll run shorter length hoses on your bike.
