    Tandem and kids

    I hace a Ventana El Testigo tandem and will be converting it so my 8 year old can be the stoker. The question I have is to what size cranks have you used to accomadate smaller riders? My son is 56" tall, the tandem currently has 175mm cranks. I was thinking 155mm like the ones on his BMX bike, but finding any that size that can accomadate a triple chainring setup is next to impossible, I can find 165mm cranks though. Any thoughts?
    Thanks for your help.

    Jeff, My stokers are my kids, I'm running normal cranks and using shortners.

    My 6 Y.O. daughter and 9 Y.O. son both ride with me and these and fit just fine. I use the same setting for both, at about 165mm and raise the seat for my son.

    Thanks for the response. Im running FSA carbon cranks and were worried about running shorteners with these cranks. I was thinking of buying 2 sets of 165mm cranks or finding some drive side only 165's . Its go to hear that your kids are OK using the 165's

    Not tandem specific but probably super cheap. It says it's a triple and in 145, 155, and 165 lengths.

    If you want to be able to use the tandem for other stokers as well, get a set of daVinci's Super Gucci rear tandem cranks. They have drillings for 130/150/170mm. All you have to do is move the pedals. Doesn't make a wide Q factor like the shorteners do, and lets you use the tandem with other stokers too.
    We have them, or you can get direclty from daVinci. Also happens to be a very nice crankset, too.

    165 work fine, Daughter is 50" tall son is 57/8" Tall (summer, they are both growing like weeds).

    Have fun with the new stokers.
