Short review on the IXS Flow's.
I have done 3 rides in them so far, a 40km rail trail ride and 2 x 30km rides with a mixture of rail trail and single track. The last ride was rail trail, road climb (inverness road if anyone knows it) and around 15km of single track with a good mix of fast descending sketchy stuff and techy peddally stuff. Temps on the last 2 rides were around the high 30's.
Firstly be wary of the sizing. The Flow's only come in small, medium and large. I have fairly large legs
(50cm @ 10cm above centre of knee) and they felt a little tight when I first put them on. The first ride they were a little uncomfortable for the first 15 minutes until they had been adjusted a few times and the right spot was found for them to sit, as well as the right amount of tension for the velcro strap. Once this was sorted they turned out to be quite comfortable. One thing I was surprised at was how cool they were when under way as they have little holes all through the cap that allow quite a bit of air flow that can be felt on your knees.
So far I have been impressed with these pads. They never move, stay quite cool and they are getting more and more comfortable as they break in. They still feel a smidge tight around the quads but I have no problem pulling them on before every ride. I haven't stacked in them yet so I will have to follow this up when the inevitable happens.
cheers.
