ok most people will say that a 203mm rotor have outright power,and to a certain degree this is true but i found that they have more usable torque aswell.

if undecided go 185mm

So would a 203 be suitable for rear brake ?

it would yes but make sure your frame is 203mm compatible.

some frames might not have room for a 203mm rotor and some frames are not warrantied for 203mm rotors.

iv got a 203 on the back and to be honest it just lockes up all the time so it would be better with a 185 or 160

i dont understand how people lock up so much. i have a code on a 203 mm rotor with a floating break, and i rarley lock up. i one finger break. just modulate the break untill your on the verge of locking, and just let it go a bit.

its not that hard

A 203 rotor on a Charge is a mega overkill!
You need something like 180.
Avid BB7's are great!
Good stopping power, very adjustable and cheap compared to a hydraulic disk.
Plus when it comes to servicing you just have to pay a fiver for a new cable compared to paying to get your brake bled.

rotor size does not give you more stopping power, you get a bigger rotor if you brake more because they cool down faster. sam hill rides 165mm rear rotor, he also doesnt ride it all day or use the brakes that much.

203 on the rear isnt needed if you ask me. Just puts extra stress on the frame.
