I have great Combi stroller which is almost perfect but the handles are a little short for my husband, who's 6'2". Does anyone know where I can find extenders to make the handlebars longer? Please don't tell me to buy a new stroller. My husband only pushes it 10% of the time so its not worth changing it to another model which may have other problems. But it'll still be nice if he can push it without arching his back all the time.
