I’ve an epiphany for the last 3yrs. I can’t say I’ve noticed this flex that some here say the frame gives. Its a solid lightweight bike that handles everything that I’ve ever asked of it. As for warranty issues?? apart from the old style rocker that snapped and was replaced in a 3day turnaround .. the frame as been solid.

Cheers for all the advice, guys. It's led me to a purchase: Ventana el Ciclon with DHX5 air. Ex demo, looks as new, black dust colour, big saving on new price. I'm sure any of the others would have been suitable, but the Ventana came up at the right price at the right time.
I'll post a ride report in due time (be around 2 weeks before it is built up).
