I wanted lightweight bike with lower gears for cycling holidays and winter use. Rather than going for a mountain bike group set I thought I would try a Sram single ring road group, though I still have a healthy scepticism about it. Getting a low enough gear is not a problem with the 42 tooth inner sprocket but it does compromise the top gear because of the small front chainring. Even getting the parts was a problem as availability is sketchy and I have to thank Paul Hewitt Cycles for obtaining the components for me. However, I wanted to use caliper brakes and nobody, at present, makes a 130mm non disc rear hub to accommodate Sram’s XD cassette, which is needed to get a 10 tooth sprocket, so I have to settle for a 11 tooth.
