different length crank arms (170 & 175) – problems?
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?

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.
ta but tandem cranks need specific drillings as stoker cranks need rings on both sides.birney29 wrote:
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.
Again ta but needs to be 4-bolt as I have the rings and everything ready to goPosted 4 years agoweekendworrier wrote:
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 armPosted 4 years ago
