I do think I need to move the seat back (in lieu of a longer captain stem) but am concerned that with the eccentric where it is i will be to far behind pedal center. Is it reasonable to roll the eccentric and remove a link?
Bike is an X/S
I am 5'11" but with monkey arms that give me a 6'4" reach
Our RT2 is a L/S so not too different from yours. The stoker bars are 46cm center to center and the captain's are 44cm. The longer stem solved any problems we might have had with with stoker bar contacting captain. My suggestion would be:
1. Leave the eccentric alone. First set up the proper position for your knees to pedals. Either use the plumb line method or, better yet, carefully measure your single bike and transfer the measures to the tandem.
2. After getting (1) right then transfer the measured relationship of bars to saddle from your single to the tandem. You may need to replace stem or add or subtract spacers, stem rise etc. On ours we were lucky that it came out right the first time.
Although not a fit issue we had the LBS put Specialized bar fat under the tape on the bars and like the shock absorbtion it provides. Stock Gatorskins were OK, but we really like the GP4X better. Good luck on a great Bike!
