Overall Product Rating 5 / 5
Very useful, but read the text

I recommend this product
ConsNeeded plenty of elbow grease!
ProsCheapest solution for short tandem cranks
Very useful thing, made the back of my tandem suitable for a 9 year old.

As it says on the information, they do need serious modification to work with alloy cranks, but it is possible if you're confident working with metal and take your time.

Thanks!
