Thank you for the advice. To answer Expatriate's question - there really isn't anything I don't like about the bike - I just want to like it more. This is my first tandem, so can only compare to my road bikes in terms of potential upgrades.
To answer Steve's question - I want it to be faster, just as comfortable and possibly more attractive.
The wheels feel heavy (and definitely don't have that "bling factor") but I'm not sure that I need to spend ~$700 on the Bontrager wheels I am seeing on eBay. So am curious to see if anyone has any other suggestions.
We are a light team - about 290 lbs - what spoke count/tire width could we get away with?
Suspension seat post is an idea - however, the wife didn't like the one she tried and isn't complaining (too much) with a standard post.
How about new tires - I have 700x28 Conti 2000 on the front and a MetroCity something on the back.
Finally what c/f fork is in my price range? Most of the replies said that I could get one within my budget.
Again, thanks for all the advice.
