Show Me Why Disc Brakes Are Awesome? Ryan Trebon Goes First

Yeah, disc brakes make total sense for cyclocross.

If you saw the race today, and the two manimals who led it all day on cantis, not to mention the laceration injuries resulting in the fields of junior men, elite women, and elite men, you'd just suck it up and realize this disc movement is just a marketing hoax.

If you feel you need disc brakes because your family made the great decision of raising you in Trondheim or Fairbanks or Helsinki or Duluth, then yes, commute to your frozen heart's content and use that as your frozen-yet-modulates defense. Otherwise, it has no practicality in elite racing.

Crazy, horrific injuries. Wonder how much Avid and Shimano will donate to UCI this year "for continued improvement on quality and safety" to keep these junk products rolling off the lines?

Just a flesh wound.

KlingOn 02-02-14 05:18 PM

Hugo Pigeon of France in the Junior Men also slipped on a bridge run-up and caught himself on the rear wheel of the rider in front of him and completely sliced through the webbing on his left hand.

What would convince you, an open jugular wound with the commentators chanting "Al'ahm d'il Allah?"

Wouldn't that be "Al'ahm d'il disco!"?

I thought cross races were supposed to be tough. Sorta' like modern day rollerballers.

Trebon says it was a chainring, not a disc rotor:

Does anybody remember a couple years ago when Luca Damiani got a nasty one?

I guess we should outlaw double-ring chainsets?

SS all the way! I mean, we need to see some real suffering. This is CX, after all.

Carbon belt drive.

This reminds me of being excited when I moved up from Little League to Babe Ruth baseball because I was then allowed to wear cleats with the flat metal spikes on the bottom.

Don't let the facts get in the way of some perfectly fine retrogrouching!

Good point! Disc brakes aren't need for 'cross! (seriously, that is my opinion)

None of this stuff is needed. I know a lot of vintage motorcycle racers who purposely limit themselves to tech that was old 40 years ago. But racing strengthens the breed, and at high levels,should be the testing ground for all sorts of cutting edge unobtainium. In the bicycle world, 20 year old tech is considered too cutting edge for some. Which strikes me as crazy.

bigfred 02-04-14 12:48 PM

Quick, someone post a link to the list of mtb xc fatalities and serious injuries as a consequence of their use of disc brakes.

Surely once the cross officials see that, they'll realize just how un/safe disc brakes truly are.

Well that's true in general about elite racing and technology. In the case of disc brakes which are more technologically advanced (or so we're told) I think you can make the case that they are overkill in some arenas. Despite their technology and advantages they just aren't needed in some areas of competition and the weight, aerodynamic, and complication penalties aren't worth it. Aren't most elite European road racers sticking with calipers?

I race cross and I don't see discs offering a huge advantage there either. You aren't going particularly fast, you just need to slow down not stop, you aren't applying the brakes for long stints where fade would become an issue, and yeah you're dismounting and remounting alot and carrying the bike so who needs a pair of spinning saw blades next to them?

No road racers are using them. But there is no way to know if they are better or not, because the UCI discourages innovation. And you may not see a huge advantage, but if they offer .1% advantage, that's enough to make a difference.

Niloc 02-04-14 01:10 PM

I guess I'm not sure that they offer any advantage to a road racer, or what they do is offset by the disadvantages, so net zero gain.

The point is there is no way to find out because they are illegal.

In light of the facts, I think the OP should be fixed:

Yeah, double chainrings make total sense for cyclocross.

If you saw the race today, and the two manimals who led it all day on singlespeeds, not to mention the laceration injuries resulting in the fields of junior men, elite women, and elite men, you'd just suck it up and realize this double chainring movement is just a marketing hoax.

If you feel you need double chainrings because your family made the great decision of raising you in Trondheim or Fairbanks or Helsinki or Duluth, then yes, commute to your frozen heart's content and use that as your frozen-yet-modulates defense. Otherwise, it has no practicality in elite racing.

Crazy, horrific injuries. Wonder how much Avid and Shimano will donate to UCI this year "for continued improvement on quality and safety" to keep these junk products rolling off the lines?

:D

Done worse than that when I was trying to just eat and live indoors for a while ..

Chainsaws are even better .. no fame and sports celebrity involved. :rolleyes:





seems most people posting here commute on them bikes anyhow or that gravel grinder tripping.

I note the Pros , like Nys that get paid to just appear,
and the whole kit they show up with is Sponsored ,
are OK with Cantilever brakes .

albeit they are carbon fiber too . ..

Andy_K 02-04-14 03:03 PM

Double chainrings are fine. You just need to make sure you keep the chain on the big ring so the teeth aren't exposed. Check the pics on CX Magazine's site. Nys and Stybar were constantly on the big ring. The Americans, who clearly aren't as safety conscious, are pictured using their small rings.

fietsbob 02-04-14 04:58 PM

some riders are in a habit of getting off on the right side.. so I suppose they're Left-handed .


single ring with 2 chainguards is also quite traditional ..

One of these for the OP and any other soccer players that find their way to cross.

I think they are good for mtb applications where you're gaining some serious downhill momentum. Otherwise I don't think they are necessary.

bingo! I agree, they make a lot of sense for mountain biking. Also heavy cargo bikes and other applications. 'Cross not so much. You are trying to go fast dammit and there aren't any sustained steep descents. You are off the brakes way before they could overheat or fade.

For fast lightly loaded road applications (like racing) calipers do just fine and are a lot lighter, more aerodynamic, and simpler than discs. Remember calipers are disc brakes, the disc being the rim. Most of the guys in the groups rides I've done are on calipers. I remember one guy had discs and they made a lot of racket, he said he's adjusted them, had the shop work on them, but basically when he rides in the wet they pick up grit and then scrape. Color me unimpressed.

If Avid and Shimano gave me 15.000€ I'd say it was a chain ring, too.

Must've been one of those one-tooth, perfect clean slice chain rings.

Seriously? You can debate 'till you're blue in the face whether or not they give an advantage (the answer; probably a slight one on occasion, probably a slight disadvantage on occasion), but this is bordering on paranoia.

On a side note, does the Trebon injury mean I need to change up my singlespeed rig...I use a triple crank (with the chainrings intact) since it sometimes switches to a geared bike :lol:
