OK, it seems the ultegra 10 is leading, but the above post gives me pause...still thinking.

Next question....If I upgrade to 10 speed Ultegra....could I put modern (10 speed) FRONT chainrings on my DA 7400 crankset?? Will this work? Please tell me I can get by with this....or do I have to shell out for a crankset too?? And what about the FD??I wish I could even keep my current chainrings as they are not all that worn, and my FD too.

If the answer is that to do 10 speed I have to get new crankset (and thus, of course BB) and FD. then the cost overrun will likely force me to choose 8 speed, for which I would only need to get brifters/cassette/chain (which, judging by eBay would only be a couple of hundred bucks).

Any probable or definite answers appreciated!
