I've been using a Dawes Super Galaxy for the past 7 years, having probably covered in excess of 30,000 miles on it. This was to replace a Dawes Horizon which had been used for about 4 years, only being replaced due to a tube shearing in half.
Dawes replaced the frame within a week and gave me an upgrade to a Super Galaxy.
I deffo recommend then as a touring / commuting bike
