Conrad at Sandman has emailed back (quickly once again) and has now seen this thread. It gave him “a bit of a fright” and he has asked me to let those who emailed and got no reply to email back (sales@sandmanbikes.com) and he will deal with it asap.
The problem appears to be that he has been travelling a lot recently with no interweb access, which combined with an over-zealous spam filter has meant that many enquiries have just disappeared. Apart from a week at Christmas he will now be home for the next 3-4 months.
He will also be getting the website and web-shopping facility up and running by January with online ordering options on frame size, colour, racks, bottle mounts etc.
Effective t/tube lengths on all models will be as follows :-
S: 580mm
M: 595
L: 610
XL: 625
