If you have to ask, you can't afford to spend the money to acquire that right to this emblem/status. Just like me.

Regarding Pompiere above on gears....there is NO perfect gearing set up despite some riders' obsession with finding it. To get something, you must give something else. Complicated shifting patterns, big jumps between gears, not enough range, much redundancy, etc. Knowing your gear inches in your head is the first step to mastering you cogset...then you can set up a shifting pattern between rings if you really want to maximize your gear jumps. On the other hand, triples and compacts allow you a ring to climb on, a ring to bail out on, a ring to cruise on, a ring for tailwinds and descents, etc.

If your terrain is varied, you might want to change cassettes depending on the kind of demands your ride will have. So much easier these days with lockrings instead of busting a gut to get a freewheel off. Big variations in cassette may also require a chain substitution as well-- to adjust optimally for length needed.
