Popped into a newsagents today and they had a bike mag I have not heard of. Bought it and I was not happy with my purchase. The content was not up to the usual magazines I read- Ride reports were not there- Bike reports were lacking in content and most of the adverts were for Cars---In a Bike Magazine? It is advertised as the Worlds leading Bike magazine and it is called Bicycling. It is, I presume going by the adverts, a US magazine but all it says is printed in the USA.
Now I don't know if this is a magazine that is rated by your standards but I found it most disappointing. Over here we have a great number of Cycling magazines and the one I prefer at present (For road riding) is one called Cycle Sport. Another is Cycling Plus. Now for mountain bikes There are a couple I could recommend. Singletrack is my favourite and another good one is MBR (Mountain bike rider). MBUK seems to have changed into a "Freeride" form of Mountain bikes so not one I now buy.
Sorry to find fault with one aspect of US riding but I think we have you beat on this side of Cycling enjoyment.
Discuss and pull me to bits but "What is a Good US Bike magazine that is worth reading?"
