currently have Dawes Streetlife,good bike but not happy with the low wide space gearing. the bike has shimano sis using a 6 speed 14-28 freewheel,am thinking of upgrading to 8 speed cassette system needing new derailler, shifters and possibly rear wheel,has anyone else gone down this road,I like the bike it has a slimline steel frame which looks more attractive to me than the oversize alloy with horrid welds.
