Got one of these (steel frame, 32X18 gearing) on Friday, rode it Saturday and Sunday and am now a total convert. Great fun, lung bursting/leg shredding workout and hardly any cleaning/maintenance to worry about! Amazed at what I could get up on it and only really spun out on road sections. Have packed geared mountain bike away for winter happy in the knowledge that the grit stone mud won't be eating its components and costing me a fortune to replace.... save money, get fit, have fun, go singlespeed!
