I bought this in 145cm and it came with a size medium strap. The grip comes with one of those old school (now new school?) thumb support thingies that you can attach if you want to use it. There is a small hole in the grip for attaching that thingie. I was worried that the hole might be an annoyance, as it's right there on the grip, but it doesn't seem to hinder use. If you don't wear gloves though it might abrade your thumb. Might be better for you just to buy a replacement grip instead of a whole pole.
