If you want a different small ring, just buy one. Then you have a 53x39 DA crank set for this price.
Just an FYI if you know what I am talking about, you probably didn't need to read this.

From back when these were on SAC.
They run small like the jerseys. When in doubt size up one from your Pearl Size.

Heads up, I bought a Vittoria tube from a local shop here. I also had these tubes for back up. I noticed that these are the same as the Vittoria tubes??
A buddy of mine is a tech at Canyons bike shop & he said that there are only so many tube factories in the world. So these have to be legit.Also, these do have the long valves on them.
Bottom line, I have used them, they work.

To all 28= 700c normal tubies
The 26 are 650c (tri,womens, etc)
Tubular Tires ("Sew-ups")
Tubular tires are mainly used for racing. A tubular tire has no beads; instead, the two edges of the carcass are sewn together (hence the term "sew-up") with the inner tube inside. Tubulars fit only on special rims, where they are held on by cement.
Tubulars existed in 6 different sizes, but only two of them are readily available these days.
* Full-sized tubulars fit rims of the same diameter as 622 mm (700c) clinchers. This size is sometimes referred to as "28 inch" or "700". It is also, confusingly, sometimes referred to as "27 inch." The "27 inch" designation is inaccurate and obsolete, but you'll sometimes run into it in older printed material.
In clincher tires, there is a real difference between "700c" and "27 inch" sizes, but for tubulars this is a false distinction. Whenever you see mention of "27 inch tubulars" the writer is actually referring to standard full-sized tubulars, as used on most racing bikes.
* "26 inch" or "650" tubulars are smaller, mainly used on time-trial or motorpacing track bikes.
* "24 inch", "22 inch" "20 inch" and "18 inch" tubulars are sizes formerly used for children's racing bikes, but pretty much extinct these days.
Tubulars are also sometimes called "sew-ups" or "tubs" (British usage.)
If you want to sound like an ignorant yahoo, call them "tubies" or "tubeless tires."
The above from Sheldon Brown.
To reduce both air resistance and rolling resistance on the road, tires are lightweight, narrow, and have a thin, smooth tread. They are inflated to a high pressure, typically around 8 bar (820kPa/120psi); track racing tires can be inflated up to c.14 bar. Until recently, most racing bikes used "tubular/single/sew-up" tires which have no beads: they are sewn around the tube and glued to the rim. These tires provide an advantage in weight (lacking the relatively heavy wire bead), rolling resistance, grip and pinch flat protection, but their greatest advantage lies in the ability to use a very lightweight simple box-section rim, rather than the U-shaped clincher rim. A U-shaped clincher rim must use relatively heavier gauge to prevent the tire pressure from spreading the inherently weak U shape and allowing the tire to come off the rim. Advances in tire technology, however, have seen the far more practical (due to greater ease of changeability) clincher (beaded) tire close the gap. Some manufacturers create Tubular-Clincher tires, where the tires are sewn around the tubes and have a bead, but there is some debate as to the effectiveness of a tubular-clincher tire. Proponents believe that it has all the advantages of a tubular tire made to fit a clincher rim, but critics argue that the design includes disadvantages inherent to both systems---the rim weight is still high, the tire is more expensive than a standard clincher tire, and repairing a puncture on a tubular clincher is as inconvenient as it is with a standard tubular tire. However, a particular benefit of the tubular-clincher design is that the risk of pinch flats is very low (like the tubular tire), yet it allows the use of the more popular clincher wheel.

DAM!!!! It doesn't get any better then Sidi shoes!!!

So I ordered these last time they came up. They are quite nice. I to like the long valve for deep dish aero rims. I have not had a flat yet.
Tech tip: If you wrap a thin layer of Teflon tape around the valve before you use these. It will keep these from rattling against the rim.
Also, make sure the valves are tight by twisting the flat portion of the presta valve to the right.

Don't forget that this will require an ultegra BB
BC has them http://www.backcountry.com/store/SHI0071/Shimano-America-Ultegra-Bottom-Bracket.

34 x 50T compacts are actually quite nice for the roads that go up through the mountains.

This is my semi-monthly chime in to let all know that Castelli runs SMALL when in doubt size UP, sometimes 2 sizes!

To all after many returns I have found that these Euro brand products run SMALL! Very SMALL! I am 5'11 & 170lbs. In race shape. (most of the time) I wear a Large & it is PAINTED on. XL if you want air into your sleeves. So if you are in doubt size UP!
Just thought that I would pass some sizing love your way. Returns are easy, just no fun for anyone.

I got mine & it had 700c wheels on it.
Wednesday, July 09 2008, 03:24 PM
Yeah! I'll risk it!

So I got the XXL last time this went up. I was a little worries it would be to big. WRONG! It was like a USA large. Castelli runs tiny.
Thursday, June 12 2008, 10:13 AM
Heads up new ChainLovers. These guys have a bangn' return policy. You no likey, not fit like you thought, you can return'em like a Netflix.
Tuesday, June 10 2008, 02:51 PM
If you wear an XL in PI you wear a XXL in Castelli.
I.M.H.O. for Castelli size up one size for active wear & 2 sizes for casual wear.
This info I have learned after MANY returns to these sites.
Monday, June 09 2008, 09:10 AM
Shipping on these was $20 for me? Where are you shipping to?
Monday, June 09 2008, 08:43 AM
So I am 5'11" & got my Castelli track jacket from the brown Santa Clause. I ordered the XXL as it was the last one thinking it would be way to big, NOT the case. If you are in doubt size up for Castelli active wear & then Size up again if you plan on wearing this sweater to the bar.
