This ^^^^^^^^^^I think the crossbars still have value for very hard/heavy riders, although the weak M-bars are a couple of decades in the past now.
I do hate it when retailers leave "no longer available" product pages up and Google brings them up at the top of searches. Amazon is one of the worst offenders.
That solves the original wobbly bar issues, but not the OP's requirement for a handgrip for a toddler.It’s easier to just fit a later set of bars, that’s what I ended up doing.
Hi there ElineIf anyone needs one I have one for sale. It’s in Oslo, Norway and I am happy to mail it.
