|If so, please let me know. Thanks.

|carbon stays would be next to impossible as you'd have issues from the canti mounts and from stay flex from the canti's. Carbon is best used for small vibration reduction (road chatter) and IMHO wouldn't be the right material for rear triangles in cx. far too much abuse. I personally think a steel fork, though heavier would provide more 'suspension' if this is what you think. If you want a carbon/alu combo cx bike. Alan of Italy (mfr of former world champ and more experience in such materials and cx than anyone) makes bikes that are reversed. Carbon main triangle with Alu stays, plus carbon fork. Cyclocrossworld has them on sale. This would be the best option for an exotic.
from your previous posts I'd suggest a custom steel rig from either Steelman, IF, Soulcraft or Kelly (who makes full sus cx rig)

|You don't have the site of this Alan company which makes the Carbon triangle frame you're talking about?
I like the idea. Thanks for the info.

|Carbon is as flexy or stiff as the designer wants it to be. It's all about how you lay down the fibres.
There are heaps of full carbon fibre mountain bikes that have no issues with canti bosses / stay flex or any of the other issues you describe. I dare say an average mountain bike gets more abuse than an average crosser.
You just need to engineer the carbon fibre to be as stiff and strong as the application demands. There is no reason you couldn't have a complete carbon cross bike if you wanted it.

|Refering to Interbike 2002, Cyclocross world reported: "Framebuilding supplier Nova Cycle shows off a carbon seatstay setup with cyclocross cantilevers. They were not seen on the floor, but no doubt they will be used by one of the many 'cross builders in the biz."|

|Looks like IRD is going to give it a go next year too!
Check out the press release on Taylor

|if you are asking if anyone makes a aluminum cross bike with carbon stays, check out www.jadecycles.com. they just started advertising their bikes on rec.bicycles.marketplace.
from anecdotal reports from my friends, carbon stays have better benefits in larger sizes. in the smallest sizes they seem to have no benefit at all (not even lighter weight, carbon-stayed aluminum bikes are heavier than plain aluminum).

|I thought Aegis used to make a full carbon 'cross bike.
That may have been two or three years ago so you may have to do some research. Also, I don't know if they are still in business.
Anyone else recall this?
FWIW, I'd just go with aluminum. Light, stiff, cheap to replace if needed.

|you are all right. Yes Aegis still does. and yes MTB's are made of full carbon, TREK makes them and trust me I understand Carbon lay-up. I still see no reason for it in cx other than weight savings. carbon's 'dampening' effects are best for hi frequency vibration (road chatter) and not for the type of hit's experienced in cx. to make CF function as so would create uncontrollable rebound. Those CF beam seat tri bikes made an MTB version and it tended to eject it riders during rebound.
I agree with pdg60 ALU or steel.
