Have a nice day
I really thought the Trek 820 was steel, not aluminum. The current 820 model is high-ten steel according to Trek's website, but I don't know about older models. Have you checked it with a magnet?zeytin said:build up the Alum Trek rigid MTB as touring/all-around bike
Did you replace the rear wheel as well as the front? If it has the stock rear it's probably a pretty cheap freewheel (non-cassette) hub with a bend-prone axle. That was a weak spot on my Trek 3700, which has about the same componentry as an 820 but with an aluminum frame instead of steel.
