Am looking to buy a buy a bike and am currently doing about 20 miles a week commuting to and from work and about 4 miles on a Sunday cycling with my lad. Have been cycling for about 20 years (mostly UK, but also including 9 years on mainland Spain and 4 months on the South of France), so know a little of what I want and don't want. It needs to be straight handled, weigh less than 12.5kg, tyres width 1.9, not sure about suspension, I am 6ft and 13 stone. Can pay up to £600. Any ideas what would be a good one to get please? Would probably go to Evans at Crawley to get it.
