We've spent this afternoon building up the 2 Titans that we've had a while and never touched.
The 20" Junior has weighed in at just 7lb excluding the B/B
The 24" has weighed in at 15lb complete but thats with a fairly hefty set of wheels until the 1 1/8ths are repaired, estimate it'll drop down to about 13lb complete once changed.
I'll try and get some pics up later but they're bloody light and look trick
