Since everyone is talking about brakes, let me ask if this sounds reasonable. Note that we do not do any kind of mountain riding with the tandem as both my stoker/daughter and I much prefer climbing on single bikes. So there are no painfully slow uphills, or screaming fast downhills. In 2005 CDale went to Avid BB7 with 8" discs front and rear. Given how we intend to ride, is swapping both out to linear pulls like the Avid Single Digit 7 a reasonable swap? It seems from comments that there is plenty of braking power from the linear pulls. What do everyone think. Please note that this would also subtract over a pound of weight off the bike for very little money.
