Hmm - found some photos of the 25 - wondering if my saddle is a touch high and if there is a better helmet for me: http://www.kimroy-photography.co.uk/gallery2/main.php?g2_itemId=526481
The Bell Javelin is quite "tall" and the tail doesn't sit on my back but around 1" away
Also put the ride into aerolab - comes out with a CdA of ~0.175 I think. Most other times I have measured it its around 0.200 so I think that shows the effect of even a relatively small amount of passing traffic!
