boemelaar_bob Posted August 4, 2016 Share Hi guysSo I have notices there seems to be a trend to have a smaller rotor on the back wheel than the front I.e. 160mm back; 180mm front.This seems a bit back to front to me. Larger rotor have better heat dispersion and braking power. So why have them on the front...Having larger rotors on the back wheel makes more sense.I use my back brake far more frequently than the front. So my thinking is that I would better benefit from have a larger rotor on the back.Maybe I ride differently to most?I'd like hear your thoughts on this.Thanks Link to comment Share on other sites More sharing options...
Captain Fastbastard Mayhem Posted August 4, 2016 Share Quite simply, the back wheel requires less force to lock, as it's "dragging" through the dirt, and your weight moves from the middle of the bike (during riding) to the front under braking. The front wheel has all the weight pushing it into the dirt, and is where the majority of the braking traction resides. Same concept as braking in a race car or bike - the brake bias is significantly front-biased. Same reason motorbikes generally have 2 rotors on the front vs 1 on the back, and cars have bigger front rotors and calipers. Link to comment Share on other sites More sharing options...

Its not really what you use the most but what stops you....front is the one Link to comment Share on other sites More sharing options...

I'd like hear your thoughts on this. Thanks I ride a 180 front and 160 rear on both my bikes. I also weigh 89kg... The type of riding I enjoy left me a little scared once or twice with a 160 on the front as it overheated and didnt bite much when needing to stop.The 160 is generally fine but Id rather have the 180 than not need it, than need it and not have it. Changed to a 180 and havent had an issue on any downhill section when needing to stop. My front brake gets used more than the back, I actually dont know how much I use my back... I just ride.

Captain Fastbastard Mayhem Posted August 4, 2016 Share As Mayhem said, plus, you should be braking with your front more, as it has more stopping power.Depends if you're predominately using it to stop. Back brake for attenuating speed (moderating it) through more technical / fast areas (just to keep the speed down without weighting the front too much) and front brake to stop.

BaGearA Posted August 4, 2016 Share I weigh 61kg and I also have a 203mm front and 180mm back ......more for unduro riding But i could probably stop faster than my car if I try hard enough Link to comment Share on other sites More sharing options...
Fr33rider Posted August 4, 2016 Share Got guides on my patrol 180mm front and back. I weigh 105kg and haven't had an issue at all. I run sintered pads. Sent from my Nokia 6310i Link to comment Share on other sites More sharing options...
BaGearA Posted August 4, 2016 Share Guides are just on another level, tested a bike with them front and rear 203 and the stopping power is just mindblowing Link to comment Share on other sites More sharing options...
