I read Cycling Plus occasionally, Australian Cyclist..as said above its free with the membership, and Bicycling Australia regularly.
Cycling Plus is not a bad read, but not much good for products in that the prices are in British pounds, and its written for Brits.
Australian Cyclist is pretty general, and mainly for non racing or non roadie types..commuting and touring.
I think Bicycling Australia covers lots of what you are looking for.
Product reviews though, depending on what magazine or writer perhaps, may not always be accurate. Some writers or magazines will rate the worst product as value for what you are spending, or similar language; in other words if something being reviewed is no good you have to read between the lines to find out.
An example is a pair of road shoes I bought a few years ago..sure they were cheap..and I read a review of them claiming they were good value for the price. Well, they were rubbish...wouldn't be good value for free.
I'm a bit careful about product reviews..depends on who is writing them.
