Need a new crankset for my tandem as the current one is welded to the BB and won't come off. Found a bargain set up on Ebay so ordered all four arms and they arrived today
Been a bit of a dope and not checked, three of the arms are 175mm so captain's cranks will match. but the stoker will have 170mm arm on the drive side and 175 on the other side
Has anyone done this? Will it be noticeable, or shall I just fit and forget? Does anyone have a right hand side square taper 175mm 4 bolt crank arm in the parts bin?

You'll have poor bunnyhop constantly walking around in circles if you do that to her!
bump for the morning crowd in case anyone has something useful to say 8)
Insoles in one foot?
Not quite what you asked for, but I have a pair of four bolt HTII 170mm crank arms sitting on the parts box that you can have for very little.
Failing that, what you need is an orthopedic shoe.
I have a square taper Shimano crankset that I am looking to sell. Right crank arm included! Used, but in good condition.
It is the black version of the shimano 2300. 175mmm crank length.
Will send you the crank arm for £10 or the entire set for £15.

ta but tandem cranks need specific drillings as stoker cranks need rings on both sides.

Again ta but needs to be 4-bolt as I have the rings and everything ready to go
lbs for a 4bolt ST drive side 175 crank.
or stick a note in the WTDs here
Willing to bet if you said nothing the stoker would never notice. Once they're aware it would feel instantly wrong.
I'd be worried about knee/hip problems with having legs spinning different circles.
Could you not just get a new BB and then use all 4 new arms?

the new arms are different lengths
the old arms were isis drive, and one is knackered
I could use new square taper at the front and old isis at the back, but would prefer square taper all round
will search out a 175mm arm
I'd totally avoid different length cranks. a friend of mine rode different length cranks without realising, for a few months & now he has serious knee issues.
sorry, should have read more carefully - thought the welded on one was the problem 🙁

this is what I was afraid of, even though it won't be used every ride.
thanks all
