What minerals are in limestone?
Bikes are usually symmetrical, there is an easy way to find out though if you are worried. Place some tape on the floor and roll your bike forward one revolution of the tire. Measure the distance. Do this for front and back. If they are the same, then your wheels are the same size.
If it's an old bike it will have 27 wheels, and those are getting hard to find new. Front wheels are different from rear wheels as they need different hubs.
primarily calcite, Ca carbonate (CaCO3) but, depending on where it comes from, it will have different amounts of silica, clay, sand, etc.
Mostly Calcium Carbonate, with some Silica.
Calcite Dolomite Aragonite Magnesite Rhodochrosite Siderite Smithsonite Ankerite Cerussite Strontianite Witherite Are all possibilities in a limestone, The first three however, Calcite, Dolomite, and Aragonite are the primary minerals of a limestone. But keep in mind it does not have to include all of these, and may have other non carbonate minerals as well
