At least you will save the weight of the Specialized alloy shim which makes the weight penalty a bit less.don't know how many grams the shim weights, but probably 10-15g. Syntace has a smaller 1 1/8" To 1" Stem Adapter with a claimed weight of 13g, but this one doesn't have any weight saving holes in the sides so the weight is probaly about the same as for the larger Specialized shim with holes in the sides: http://www.syntace.com/index.cfm?pid=3&pk=523

Claimed weight for the Specialized S-WORKS Pro-Set Stem is 150 g including the alloy shim.
How close are the real weights to Specialized's claimed weights?

You can buy the three different Specialized 1¼'' stem models at this German webshop:

I'm not sure about full compatibility of specialized stems with canyon's fork. We have all heard a story here about a stem that was correctly torqued and fork's steerer tube cracked cause the stem's force was applied on a smaller area when compared with ritchey and syntace stems. I woldn't take the risk of trying specialized stem.

How much do they charge for that stem?


It was 85 EUR. And then they wanted something like 80 EUR for postage to Australia :shock: . But I managed to get it for about 90 EUR all in after a bit of negotiating by email.

How many headset spacers does Canyon ship their bikes with? Or does that depend on the body measurments you tell them while ordering?Of course you can't add extra spacers if the fork has been cut down.

Reasonable weight (160, but I'm not clear if that includes the shim, so possibly lighter for the 1-1/4 application). S-works will drop about 10 grams. Also, if you watch E-bay long enough, you can find a white one, as I did! The white only comes stock on a couple models and is not available through the website. But its hot and worth the wait.. if you're into the white stem thing.

The white stem is available through their website now: http://www.specialized.com/us/en/bc/SBCEqProduct.jsp?spid=41846&menuItemId=9305&eid=5135
Do you us your white Specialized stem on a 1¼'' Canyon?

Nope. Plain old boring 1-1/8" Kona Jake the Snake. I needed more drop on my cx bike and was looking for silver or white stems in -17 110mm. Found this and it has worked out well. I also recently picked up a 120mm -17 Ritchey wet white to get really close to my road position during winter and fire road rides. However, I must say, I think the shim setup may reduce stiffness, and it really complicates having spacers on top of the stem. I had to find another -16 shim, cut off the solid metal lip, and use that as a mirrored spacer on top of the stem before I could add a regular 5mm spacer and top cap. The ritchey setup is stiffer and simpler.

But again, all that is using this stem with the shim on a 1-1/8". 1-1/4" use should be simple, and maybe stiffer.

Have any of you tried the Specialized stem? I just bought one based on the recommendation here and there is no way that is 1.25. It's way too big. I bought the exact stem shown in the picture on the previous page, and was really excited to finally get more drop only to discover it didn't fit.

Maybe I'm doing something wrong here but I doubt it. The Pro Set stem is (according to me) larger than 1.25".

BTW the 120mm stem weighed around 146g and the shim was 18g. Not too bad.

1¼'' - 1⅛'' = ⅛'' = 3,2 mm

This should be the wall thickness of both sides of the shim combined. So only 1,6 mm of wall thickness on avarage for the shim.

The shim does look thicker than that, but it's har to tell from the picture and the tickness isn't constant all the way around, that's the whole point of the shim after all, to make angle adjustable.
So you might be right the ID of the Specialzied stem is ment for bigger than a 1¼'' shim.

Maybe you can get a machine shop to fabricate a shim to fit the Specialized stem, with an inner diameter of 1¼'' instead of 1⅛''.
Or maybe you can fabricate your own from a beeer can or something thicker than that.
Or maybe you can use a USE shim with an inner diameter of 31.6 mm (very close to 1¼''):

Canyon has got Ritchey WCS stems in -17 degrees now, so no need to use the Specialized stem. Just check my signature.

Any updates here? I wish Thomson would do a 1 1/4" X2 :(

Just about every 2012 giant road and mtb is coming with a 1.25" steerer tube and giant says aftermarket offerings from the major stem manufacturers will be making their way into the aftermarket this fall or sooner. Nice side effect for you Canyon owners.
