Since launching the bmxultra.com Reverse Look Up Gear Calculator a week ago we’ve refined it to make it easier to use and added Decimal gears as a display option (this was done an ode to @Snapongreen).

The original online Gear Calculator has also had an update. We’ve added the Answer Carve 20 x 1 1/8″ and 20 x 1 3/8″ options as requested by a bunch of people recently. A big thanks to John Sawyer at Answer for providing the details to make this possible.

It looks like we’re going to be busy adding Decimal gears to this calculator too some time in the near future, keep your eyes out for that one.
