All the M-Trax Titaniums I've seen have a model name like Ti-1000 or Ti-2000. This looks to be just badged as a "500" - which was the naming used for the full steel frames.
proof if proof were needed.
it has Titanium main tubes with cromo rear triangle
i appologise for the poor pics of the special products card that came with it.
batteries were running low, i'll get better ones when they've done charging.
