Gear Talk / Tandem crankarm length
« on: February 12, 2004, 08:15:06 pm »
I just bought a used Trek T-100 tandem bike.  I think it's going to be fine for me and my 13-year old daughter next summer on Cycle Montana, but I have two concerns that you more experienced cyclists may be able to help me with.  First, the crankarms are 175 mm.  Is this too long? I am 6 foot, and love the 172.5's on my road bike.  My daughter is less than 5 foot tall, and I worry about "beating her up" on the flats.  Would it make that much difference changing the arm lenghts to 170?  Second, my rear gearing only goes to 28T.  Is this a disaster in the making?  I remember how hard it was to climb Rogers and MacDonald pass last summer on my road bike, and I don't want to needlessly suffer.  Any suggestions?
