I have tried twenty niner riding,it used to be called a hybrid (falls over laughing) I had a claud butler reynolds 531 frame with full campag and whilst it was a v.nice bike,it was a road bike with flat bars and slightly nobby tyres. Bike design has moved but backwards as there are only so many types of bike.The hybrid of today is now the ""29er"" of today.Notice how it has less letters than Hybrid,another example of lazy language de-generation :!: In about 25 years we will just be grunting at each other (pretty much what hoody wearing chavs do now) to be human in the modern world.
