The Drongo Posted March 31, 2011 Posted March 31, 2011 I don't know what happened here, so I am not really commenting on Kevin's scenario.But regarding brakes and this is just my opinion.Brakes can get moisture in them, yes even fully sealed systems, and we are not talking a lot.Moisture, condensation, oil and heat don't really work well together.I will conclude by saying this, too many people bleed brakes without getting rid of all the old fluid first.On Avid brakes I actually "suck" all the old fluid out and bleed complete with new brake fluid, this should deal rather well with the dreaded "brake fade" issue.And no, I am not here to debate this to end in this topic, if there are those who feel the need to argue, then create a separate topic on the issue (where I will leave it open to the experts again) 100%
The Drongo Posted March 31, 2011 Posted March 31, 2011 Who, Evans on the Elixir 5's ? Dude. I well understand that these top guys often run 'Blackbox' items not even released to the public, but on most of the pics of their 2011 ride they appear to be Elixirs. Which are pretty good, notwithstanding. So the rotor issue must enter the fray too. But am open to correction here. The initial question is still unanswered. What brakes?
The Drongo Posted March 31, 2011 Posted March 31, 2011 (edited) That's a Scrub rotor ? Riiight. Thanks. Now find me a pic of them brake levers! Composite rotors, wrong pads? - Eish! "Please be aware that sintered, semi-metallic or full metallic pads should never be used with Scrub rotors. Use only organic or resin pads! If you use a brand other than Scrub or Kool-Stop, be sure they are 100% organic. Use of any other pad may compromise performance and/or void any support that we may offer."

What brakes?XX brakes.Reason I asked who you were referring to, I wasn't sure
Weight Weenie Posted March 31, 2011 Posted March 31, 2011 AFIK Kev an Dave can't run Blackbox as they are not part of the SRAM program ? But they would probly have the XX World Cup version which is just the production version, if that is out yet. Or just normal XX Dangle ? Maybe now people will stop giving Sauser moeilikheid about using only 3 disk bolts
The Drongo Posted April 1, 2011 Posted April 1, 2011 XX brakes.Reason I asked who you were referring to, I wasn't sure Cool. So that would include cleansweep rotors then, which in a poor video-shot could look like Scrubs?
Wyatt Earp Posted April 1, 2011 Posted April 1, 2011 Cool. So that would include cleansweep rotors then, which in a poor video-shot could look like Scrubs?XX World Cup, which just has an adjuster added at the lever.The rotors are Scrub/Scrap.One has to wonder how durable magnesium is when it get's machined to almost nothing.
The Drongo Posted April 1, 2011 Posted April 1, 2011 XX World Cup, which just has an adjuster added at the lever.The rotors are Scrub/Scrap.One has to wonder how durable magnesium is when it get's machined to almost nothing. And has ceramic in the mix! Back to Shimano - Ta!
Wyatt Earp Posted April 1, 2011 Posted April 1, 2011 And has ceramic in the mix! Back to Shimano - Ta!Sure but don't use Scrub I have XX brakes, not a day's wort of trouble.Avid Elixir Mag's on my SS, not a day's worth of trouble.
DaLoCo Posted April 1, 2011 Posted April 1, 2011 Sure but don't use Scrub I have XX brakes, not a day's wort of trouble.Avid Elixir Mag's on my SS, not a day's worth of trouble. I would venture that you would check your brakes regularly, but not service them after each ride KE's brakes were serviced after every stage, so he was basically going out on new brakes every day
Wyatt Earp Posted April 1, 2011 Posted April 1, 2011 I would venture that you would check your brakes regularly, but not service them after each ride KE's brakes were serviced after every stage, so he was basically going out on new brakes every day There is no need to service/bled them everyday.I will take a bet that what they mean by service everyday, will just be a general check on pads and adjusting the caliper with the rotor to check for brake drag.
The Drongo Posted April 1, 2011 Posted April 1, 2011 I would venture that you would check your brakes regularly, but not service them after each ride KE's brakes were serviced after every stage, so he was basically going out on new brakes every day Yea. Don't know about bleeding everyday. But scrub rotors apparently require regular pad changes, and new pads don't bed in easy, when they do they don't last too long. As Evans says on his tweet, too far, too fast, too hot. Accident. The price you pay for light vs strong. Titanium - now that be light, and strong - He got some
splat Posted April 19, 2011 Posted April 19, 2011 From Brandon Stewart's Twitter:Dear Sram please can you do something about your XX brakes..... Would be nice!!! about 18 hours ago via ÜberSocial Kevin agrees:Sincerely, collarbone. RT @bsbrandon5: Dear Sram please can you do something about your XX brakes.....

SwissVan Posted April 19, 2011 Posted April 19, 2011 So following this thread with some interest...It appears as if KE was using SRAM XX brakes and had an aluminum disk. 1. Do Avid/ SRAM make an aluminum disk? 2. WTHell was he thinking IF he had alu disks. for evans sakes his old ballie designed the course surely he would have said "Son dont use alu disks on that stage". BTW for those wondering about the new XTR disks, i used and rode all the downhills (that we were allowed to) using XTR 2011 brakes wif stainlees / Alu combo disks and they performed flawlessly.
banna Posted April 19, 2011 Posted April 19, 2011 My suggestion would be to simply put a more robust brake system on your bike for the Epic. The terrain in the Epic these days is really challenging and you're taking a big fat chance using these feather weight parts. Just put something like XT brakes on, and you will go for 700km's without a squeel.
