Hi guys,

My Juicy 7's have been sold on the bay and the K24's in my basket

Decided on 200 rotor for the front and debating whether to go 180 or 200 on the back - there is £2 difference for the bigger rotor.

I do aggro XC mainly with some steep downhill.

a 180mm on the rear will be harder to lock up right? but won't cool as fast? I want a lot of modulation and control and hate grabby brakes.

Or is 200mm too big up front too?

Thanks guys

200 front 180 rear and works rgeat!

That's the setup I'm running with my K24s, works amazing. My bike is a hair over 38lbs right now, I think if It was a little heavier I would prolly bump up to a 200 rear. Regardless, the K24s are awesome brakes!! I'm getting a second set for my Slalom bike.

Get The One if you want to run smaller rotors.

Thanks guys,

i'm 13.5 stone / 189 pounds

180 on the back sounds good then. Would there be *any* advantage to 180mm up front ? apart from saving 30grams in weight.

I'd stay with a 200 front, the 30 g isn't worth saving in this case.

What width tires are you running? If you are running 2.3 in the front and rear, 180/160 should be fine. If you are running 2.5, 200/180's are good.

I am running 180/160 on my Kona Dawg with a 2.5/2.3 tire combination. This set up is gear specifically for Downieville, with long rough straightaways.

personally i say go with 200/3 front and back. the weight is a non issue and they have more power if you need it. one things that i have always given formula credit to is that their brake can modulate like no other so don't worry about them being too grabby.

that being said i use 160mm on the xc bike front and back. currently i have the same on the all mountain bike but that is soon to change to 200mm front and back for those long ass downhill i encounter time to time.

Thanks for advice guys

Running conti Vertical Pros which are 2.3 (but more like 2.1 in reality) bike is a Santa Cruz Heckler weighing in at 30.5 lbs.

Ive ran 160 Hayes on the back and heated them up real quick hence went to the extreme and swapped for 203mm Avids. On the rear I find I can lock up the wheel a bit too easily sometimes, on the front well I don't use the front brake as much as I should on downhills. oster_oops:

I'm thinking if 180mm makes it harder to lock the wheel up front and gives slightly better control/modulation that could be the way to go, especially with my 2.3 tyres?
