Guessing those go under the gloves? Do these really provide armour, or just support?
As far as I’m aware, the idea of wrist protection is to prevent the wrist from being bent backwards rather than to provide armour against impacts. I use some Dainese wrist guards whilst snowboarding that have helped me avoid injury in many nasty falls! They are quite old though and don’t look like the current ones, more like these only the protective strip is a lot chunkier. They need to go on under roomy gloves though, which could be more of a problem for cycling. I’d have thought that these, along with some decent gloves (with gauntlets if you’re being really serious!) would provide all the protection you’ll need.
EDIT: something like the 661 wrist-wrap might be more appropriate for cycling though, as it goes over the glove apparently (see above!) as long as it offers the same level of protection!
