So how many people do you think will run out and buy Tacx Cermic Pulleys tomorrow...

I saw the story last night and went ahead and placed an order... because it's derailleur pulleys that are keeping me from riding like Sven.

right.....

I'm running out and buying an ultegra seatpost today! What's up with the 140 stem? That just seems like it would handle weird. Oh well, doesn't look like it's hurting him at all

Other things to notice:
He only uses the bottom pulley
It is replaced every race( like a lot of things on his bike)

I tried these(on the road). They work great(only on the bottom because the top doesn't float enough for great shifting...not bad, but not great).Until they get wet....then the ceramic balls eat the steel race....then they no work so good.
But I think everyone should go buy some right now.......

I wonder if the Enduro pulleys would do the same thing, with the ceramic chewing up the races.

Most of the euro pros run long stems..especially on the road.
Got to dig that seat post......goes to show you that being a weight weenie ain't all it's cracked up to be. I have a C50 cross....mine weighs about a pound less...hasn't put me on any podiums

That's a Colnago deal. He's (Ernesto Colnago) a weird cat and likes long stems on bikes, he WILL NOT make a frame to you're specs, you ride what he thinks you should be on. Johan Musseuw hated him for that when he was on Mapei. When he swithed to Domo, he made a dig at Colnago about this and how Merckx made him a bike that actually worked correctly.

OK...I did a search...guess you haven't posted any pics of your C50 Cross. So let's see it...how about a couple pics.

Yes....I was surprised when I saw the weight of his rig at 17.9lbs. I was expecting less...especially with the carbon Spookys.:p

120 stem.. Where did you guys read 130? I think it's neat how "common" his bike is.. Didn't say anything about all Ti bolts or any other super trick components. Very interesting.. 5'11" and 156lbs though is crazy! I'd like to weigh just 170! (now I'm 200) :eek:

The one 140mm measurement was under one of the pictures, but is listed as a more reasonable 120 in the component breakout.

I'm about 6'3" and weigh 170... like I said I should be just one ceramic derailleur pulley away from WC contention.... right.

Mine haven't...

Most people who talk sh*t about ceramics don't have them...

I have the Enduro BB and pulleys and the drivetrain is WAAAAY smoother. The BB spins almost as freely as an old Campy spindle BB...

I'm aware of some pro peloton guys riding silly long stems (I think pozzato runs a 140, as does bettini) but seems like it would throw you pretty weird on a quasi off road machine. 120 makes more sense.

...that's what I weighed a few years ago when I was riding a ton. Last winter I Nordic skied a ton...end result: 171lbs. Wasn't so great on climbs last summer. :(

Most people who talk sh*t about ceramics don't have them...Nobody here is talking sh*t. This is an issue that Enduro brings up to raise questions about their competitors (so I guess Enduro is talking sh*t). Its a legitimate question.

Among SRAM's new offerings this year are some products that integrate ceramic hybrid bearings. While a step in the right direction, we would have expected the engineers at SRAM to know a little bit more about bearing materials. Take, for example, their new ceramic hybrid derailleur pulleys...

SRAM's choice for the bearing race material is stainless steel. To understand why stainless is not well suited for for this application, one need only keep in mind one of the main reasons for using ceramic balls in the first place: superior hardness. Ceramic balls are more than twice as hard as steel balls. This increase in hardness results in longer bearing life and less ball deflection. The idea of "hybrid" bearings is to get the best match possible between a ceramic ball and a non-ceramic race. This is why Enduro Ceramic Hybrid bearings use a specially treated chromium steel (52100) for our races. Here are the hardness numbers in Rockwell C-Scale:

Ceramic Ball (SI3N4) ............... 75-85 Hardness
Stainless Race ........................ 58-60 Hardness
52100 Race ............................ 62-64 Hardness

While a 2-6 point difference between the stainless and chromium steel may not sound like a lot, the hardness scale is exponential, and this difference translates into a 15-20% increase in bearing life.

Since one of the main reasons to upgrade bearings is to reduce friction, ball and race compatibility is critical. The grain structure of stainless steel will not allow it to take as fine a polish as our treated chromium steel races.

Our jockey wheels weigh in at 9 grams for the top pully and 10 grams for the lower pulley including our anodized dust covers. The SRAM pulleys come in at 12 grams each. http://www.enduroforkseals.com/id188.html

I think having a longer stem would actually make the handling more stable?

I don't think 2cm is radically different in any event. Since most lines top out at 130, 140 just seems that much more pro.

There is something very understated and correct about Nys' rig.

Starting with a black Colnago frame certainly doesn't hurt.

It's nice that there's not a whole lot of funky widgets or "made by my uncle, back in the shed" silly parts. Just straight up good frame and quality components. I mean, it is the best, but it's all pretty much off the shelf, no?

I was surprised, too, that he didn't have whole lot of fancy parts, but he still has some nice wheels. As I recall, does he have 4 or 5 bikes for each race and something like 20 wheels that he brings to every race?

Go to a World cup.
There are about 40 riders.....
There are over 150 bikes for those 40 riders.......
There are over 300 very trick wheelsets for those riders.
When you watch a mechanic trying to push 4 bikes and carry 10 wheelsets(mostthat are not available...or out of the average Joe's price range) to the pits....it makes it look like the rider has the easy job.
The bikes....while they often have very working man's stuff( like Sven's Ultegra seat post)...are often one-off frames...or wheels...or tires...or components...or any combination of above.
I get Wood ( with a capital W) walking around the paddock area.
