I'm pretty sure I've decided on an Explosif for my next build/restoration! This is great inspiration!
I rode my friends 2006/7 Lava dome recently at a downhill park in Wales and it was so fun to ride, so now I'm on the hunt for a good steel frame to start from.
The Lava Dome had adjustuble dropouts for the rear wheel which seemed pretty cool because you could get 650b wheels in there, and from some research I found the Explosif had a similar feature around the same time, and apparently a better construction than the Lava Dome. So if anyone comes across one, let me know!
