Wanted R3000si Crown Race

[rooney]

I have an R3000si fork, but no crown race. These had a proprietary Cannondale race that is nearly impossible to get any information on. I don't even know what it looks like. The most info I've gotten so far is an image of a page that accompanied a crown race kit from a FB group.

If anyone has one, or a lead, please let me know. Thanks!

Do you have the frame and the rest of the headset? The SI frames used 36/45 degree bearings. Since the crown race only contacts the bearing on the bevel, I would think any 1 1/8" crown race with the correct angle would work. FSA, Cane Creek and others made these headsets. Lots of Cannondales came with FSA headsets, some with Campagnolo. This Cane Creek race should work if you have everything else.

I should have included photos of the fork. The odd thing about this is the bevel where the steerer meets the fork crown. It makes most crown races useless.

That's interesting. I have a CAAD6 that I assume has a carbon steerer but I would have to check to be sure. Also interesting to see that it's a Time fork. I thought that all the Time forks predated the SI era.

Again, do you have the frame? If so it would make tracking down the age much easier. I've spent a lot of time looking through old catalogs and haven't located that fork.

The bottom of the IS-3I race does have a chamfer. It appears to be 45 degree and about 2 mm wide.

The fork is from a CAAD 5 R3000si, so 2002ish. I bought it without knowing it required a proprietary crown race. I don't have the frame. To my knowledge, the rest of the headset is standard, integrated 45/45 Campy style with only the crown race being different.

Do you think the chamfer on the IS-3I is to small to work?

I think the fork came from a 2003 R3000. They dropped the SI from the model name that year. I have a 2002 R3000SI. I can pull the fork if seeing the crown race is going to help.

If you look at the 2001 catalog, page 35, the R3000si matches this fork pretty closely. This one is a single color instead of the fade in the catalog, but googling "2001 Cannondale R3000si" yields results with a single color blue fork.

As for the IS-3I, I couldn't say. I did a little googling last night about the IS-3I, but couldn't find posts about anyone using one on an SI fork. But I also didn't do an exhaustive search and I was a bit tired when i was looking. The measurement at the flat part of the steerer, just above the angled portion, is 30mm. Above that shoulder is 29.5mm. The measurement at the base of the angled portion is 32mm. The angled portion seems to be 3mm tall, as does the 30mm diameter section above. I don't know if any of that information is helpful.

Did you look at the 2003 catalog? The R3000 was available in black with yellow/gold decals that year. Looks to match the colors on your fork.

I will try to remember to measure the Cane Creek race more accurately.

Today I went through my forks and found a Time fork that had an even more pronounced radius at the crown. It has an aluminum steerer. It's a new fork, never installed but I don't recall any of the purchase details. So it kind of seems that this might have been a Time trait, which makes me think headsets other than Cannondale exist.

The photos I posted don't show it well but this fork is blue and looks like an exact match for the 2001 model. This isn't mine, but it captures the color accurately.

OK. I thought it looked like black with gold decals. The catalog says the headset was a Record Hiddenset. I'll look to see if I have one. But that doesn't rule out a special crown race. It sounds like the bevel of the IS-3I is a bit too small to clear the radius on the fork. I suspect the radius was the source of people's problems mentioned in the service bulletin - getting the race seated properly was likely harder to do compared to seating it on a flat surface.

I have a NOS Time fork with AL steerer that has an even more pronounced radius at the crown. Someone must have made races for these forks. I would try talking to someone at Cane Creek.
