our new tandem--and so NOW we need to. . .
we bought a late-90s santana sovereign sunday with fewer than 1500 miles on it. it has been hanging in a garage the past ten years, and is like new. still has the original shimano bar-end shifters, hyperglide 12-32 8-speed cassette, and 54-44-28 triple up front.
--i flipped the captain's stem to get me in a slightly more normal position, but we need to get a couple seatposts that do not have the enormous offset. looks like shims might be needed for a while, until i have the $$ to buy thomsons.
Q1: do shims really work? i'm always a little suspicious.
--now, about the stoker stem: it's as bad as the captain's stem for rise.
Q2: where can i find a non-adjustable no-rise stoker stem?
--i'm a little perplexed about what to do about gearing. on my road bike, i run a 53/39 and 11-25, and my time trial bike, it's 54/42 and 11-23. is there some "tandem" reason [with which i am not familiar] to keep these? i'm going to lock out the little granny up front, and would like to employ a 54-42 or 54/39 with an 11-something.
Q3: will a 9-speed cassette fit on this bike, and work with the bar-ends [which i kinda like]? and will i burn in tandem hell if i DO change the front middle ring?
thanks for any help you might offer. i'll keep trying to post the photo...
