Finally had a chance today to do some mid-speed runs (30-40mph) over a heavily corrugated/mogul heavy trail. Much more corrugated than anything I've experienced in Death Valley for sure. After a half mile or so section, I took the surface temps of my shocks (twin tubes in front and monotubes in rear). Before getting to the temps, I gotta say I'm really happy I made the switch from 705 valving to the 701 valving (50701 shocks). The rear is SOOO much more controlled now on the rough trails. Yea I can feel more on road but the trade off was worth it for the off road control.

Anyways back to the shock temps.

Always heard that monotube shocks cool off quicker than twintubes. Made sense due to how they are constructed differently but never got to test it till now. Did a mogul heavy trail today and got my rear IMS monotubes up to 235f. Front twintubes were around 155f. Both temps were surface temps so actual fluid temps were likely higher.

After taking a short 6 - 8 min break, the twin tubes dropped to 140f while the IMS monotubes dropped to 175-180f. With these numbers in mind, I'll eventually switch the fronts to IMS when my current ones fail!
