Can I ask where you got your handlebars? They look just like what I need for my home built beastie.
I do like the bike – Kinetics had one secondhand a while ago and I was sorely tempted!
The handlebars are a standard set from velo orange (I think they call them 'Left Bank' handlebars) with an extension to lengthen the bars and get them closer to the seat. They are flared slightly, so the bars are quite wide at the end and provide plenty of clearance for my legs. The extension was made from the original aerobike handlebar / fairing frame. It includes an internal tube to join two sections of handlebar together, and an external bracket to hold it in place.
Interesting to see the price for the kinetics one - from some adverts that a friend found from the 1990's this model cost £1,450 new.
