The new push-rims have been fitted and they are really good! I went to our local cycle shop and “borrowed” his worktop to swap the rims over…and a little bit of persuasion with a hammer!
My wife says the rims are better as they are a bigger diameter, and the flatter edge is great for her to propel herself forward, but also better to stop. The grippy coating is really useful in this respect. And they are not that much heavier than her old rims.
