This is the first of what is probably going to be a lot of questions in the future as I'm putting together a new tandem from the frame up.
My son finally outgrew the trail-a-bike (he's about to turn 8 and about 65 lbs.)
I have the wheels, seatposts/seats, rear derailleur,V-brake calipers, and fork on the frame already. Cranks, BBs, front derailleur,stem, bars, and Ergo shifters are waiting to be put on.
I have a stoker stem (adjustable) that is 29.8 diameter. Problem is my seatposts are 31.6. Before I start hunting on the internet, is there such a thing as a 31.6 stoker stem? No matter how much I try to spread the stem I cannot get the seatpost through it.
I need to know how many chains to buy for the drive chain and for the timing chain.
I also need to know a good brand of brake/derailleur housing to use and how many sets I need to buy (I've found extra long cables and travel adjusters already).
Any help/advice would be appreciated.
I built a half bike this way but this is not going quite as smoothly.
