Help- Upgrading bike -What shifters to get?

Hi,
I am upgrading our tandem and will be going to a 10 speed set up. I will be getting Ultegra shifters, my question is do I go with the Ultegra 6603 which I can get for about $200. or do I pay more (about $350) and get the newest Ultegra 6703 shifters. Both sets of shifters would be new. Thanks

Both will probably be reliable and work very well. The main difference then is the shape + ergonomics and the look. Now, that is very personal. Did you try riding bikes with 6603 and 6703? If you are familiar with 6603, you could try to test-ride any new single bike equipped with 6703 and decide on the option that "feels better."

I personally really like the 6703 "trigger" shape and the sleek look of black composite levers with internal routing cables. 6703 also has increased brake cable pull and I heard that it is not necessary to use travel agents when using these levers with v-brakes. Actually, if anybody here has tried running 6703 levers with v-brakes without travel agents, I would love to know your experience. Does it really work?

An option you might want to consider if you want the shape of 6703 but not the higher price are the new 105 levers. They are very similar (identical??) in shape and functionality to Ultegra 6703 and they also have a black-colored option. Co-motion is now using 105 on their Primera and Mocha tandems.

I like the Campag ultrashift. It is good being able to go through more than one gear at a time. Would need a J tek as well if the rest is Shimano.

Thanks for the advise, I think the increased brake pull would be helpful. I will be using a road caliper brake on the rear and on the front an Avid BB-7 disk with a 203 rotor on a carbon Wound Up tandem duo fork.

I just built our new Calfee and used 6703 shifters, I have 6600 series on my road bike and like the cable routing of the redesigned system. The 6703 system shifts extremely well. I had Campy on my last road bike and prefer the Shimano shifting system. Just my preference.

Sorry to hijack the thread a bit, but we are considering to upgrade to Wound Up duo fork and BB-7 disk and we can't decide whether it is worth the money and trouble. Did you retrofitted your tandem with that set up or was it the original specification? If it is a retrofit, did you notice a sizeable improvement in handling/ride quality/braking? Any other details we should know about when pondering this change?

Our new tandem is a older tradition design Calfee Tetra, our old one is a Co-motion Primera, it came with disc brakes but we added the carbon Wound up disk fork. The Calfee has a carbon fork deigned for a road brake caliper. I found the carbon fork to be better in soaking up the road vibrations than the Co-motion steel fork. I really like the
Avid disk brake. We live in the prairies but when we go biking in the Rocky mountains I appreciate the extra stopping power of the disk brake. ( Our first tandem was a Trek T-1000 which did not have disk brakes).

One more up-grade question?
I have decided to go with the Ultegra 6703 shifters. Should I use a Ultegra rear deraileur or go with a Shimano XT so I can use a bigger cassette? I believe that the largest cassette is 28 teeth for Ultegra as opposed to 34 teeth for a XT Deore cassette.

Per Shimano specifications:
Ultegra RD: min sprocket 11T, max sprocket 28T, total capacity 33T (shorter cage) or 39T (longer cage)
XT RD: min sprocket 11T, max sprocket 36T, total capacity 35T (shorter cage) or 43T (longer cage)

If you want triple chaincranks, you would need the longer cage version of Ultegra. Maybe the same applies for XT, depending on your chainrings.

However, I think many people run Ultegra 6700 RD with SRAM 11-32 cassettes. For instance, that is the OEM specification on Co-motion Speedster and on our 2010 Primera. We didn't have any problems with that set-up and are entirely satified with shifting performance.
