Best brakes for 29er marathon races
Moderator: Moderator Team
Hi,
I do consider racing the Grand Raid in Swiss, wich contains 5060 pos alti meters, so every gram might count………. But, regarding the alti meters, I will need proper brakes, since I will use them hard over that day.
At this moment, I do have the 2012 Shimano XTR BR-M985, race – 160mm floating discs.
Would you guys recommend me some other brakes, weight wise and braking power ?
Anyone with tire recommendations for this event ?
Thanks in advance,
Ced

Depending on the descending, length/gradient etc. i *might* go up a size on the front disc.
Doesn't even have to be a permanent fit, i've experimented with running 160/140, 160/160 and 180/160 and it's only 10 minutes to swap both ends and tweak. (Given that you have the same disc and adaptor type of course)

I have done Grand Raid and Salzkammergut 200km this year with R1 (swissstop organic pads) 160/140mm rotor, Pythons 2.0".
I felt good on downhills, but, next time I will take something wider, like Maxxis Ikon 2.2 for stability

I have tried 160mm on the front for XC racing in the flats of East anglia and got brake fade with Hope mono mini's and disc with alu carrier. Now granted brake tech has moved on but I would not want to run 160mm rotors on the front for serious fast descents that are long. 180mm rotors are must and would be fine with your setup.

What is the actual disc that you are using? This can make a big difference. For example, a 160mm Ice Tech disc will probably provide better performance than most Swiss cheese'd 180mm rotors. If you're not already using something like the Shimano disc, keeping your already good brakes and swapping to a different disc of the same size (with a pad change to suit I guess) seems to be an easy and cheap way of getting better performance. It's easy to switch back to a light disc for flat rides too, especially if someone has more than one set of wheels.
Hi,
Worth to try, but the GR I will defenitly need the 180mm disc.
I was in that area this summer with my 2x 160mm Ice tech rotors on green Swiss top pads.........
Especially the big amount of descending on 1 day without the opportunity to swap brake pads ;o(
Tx for tips and idea's
