Im several years gone from riding so Im just coming up to speed on things like tires. So the Trailmax is not such a good choice for this terrain, it sounds like?. More like a 50/50 hoop is the better choice. Also being a native northwesterner Im also more familiar with hypo, rather than hyper thermia. (I did recognize it once in a sport bike dude that came into a bar I was at. He was wearing a track suit sort of affair on a 90 degree day. ). Sounds like in addition to the "normal" precautions/gear - go early. Spend some time learning about hyperthermia. Be prepared to back out or take more than a day (camp) so you arent pushing yourself into danger zones. Ive generally done day rides in the past and Ive set myself an alarm at which time I am to turn around, no questions. Just thinking out loud. Its stuff for me to consider because I love the desert that I have passed through on pavement. A grand adventure for sure, gents!
