He he.

Quoted message said:PS: If it's not a terribly rude question, what does your
frame weigh? Is your bottom bracket attachment the
same as on the Dutch Speed Bike?
I haven't weighed it yet, but it's "not too heavy". My gut
feeling is=20 that it weighs in at less than the Street
Machine but obviously doesn't=20 have the bonus of rear
suspension.
The interesting thing is that the weight appears to be
distributed about=20
50:50. The CoG is high enough to mean that a solid brake
with the front=20 wheel can lift the rear of the bike
(There's not much danger of it doing=20 that once all
the camping gear is on it though ;-)).
The bottom bracket attachment is frankly [censored] and in need of
revision.=20 It's based on the same design but uses a
complete shell and two 2mm=20 (thus flexible) steel plates
with four bolt holes. The problem is that=20 the plates have
to be distorted a lot before it generates enough=20 clamping
force to resist the force of the pedals.
I plan to use our milling machine (and a jig) to make a
steel version of=20 the beautiful machined aluminium jobbie
that Dutch Speed provide.
The basic principle is however, the same.
And with regard to cost (Which I forgot to mention) back of
an envelope=20 maths suggests a figure between =A3300 &
=A3350. Probably nearer the latter=
=20
once I've sorted out a new front wheel!
