Did a trial fit of the 2x2 Cycles rack and mountain bike to the Strom today.
The carrier is an older design so I need to find a welder to modify it so it'll take modern through-axles, but it seemed to fit the old MTB OK (it needs a 15mm piece of tubing welding to it instead of the current mount). I might also modify the base plate to make it narrower so I can move it further forward in between the grab rails.
It was too windy for me to bother trying to ride with it, and it rained quite a bit after the photo was taken, but I'll post a proper review once I've been out on it.
If you look closely, the front wheel of the strom is just off the ground so I best avoid using the centre stand when the old MTB is on the back.
