The Birch Crossover Drop 5 I13 is a yellow birch wood bat offered in 29, 30, 31 and 32 inch sizes, with a cupped barrel end at drop 5. The page describes a tapered knob and standard handle with a longer extended barrel, and a 90 day limited warranty against manufacturers defect.
| Model code | I13 |
|---|---|
| Wood | BirchWhat this meansSofter than maple and more forgiving of mis-hits; hardens with use. A good choice for a first wood bat and for younger players. |
| Wood grade | Finest Grade Yellow Birch |
| Drop | 5What this meansDrop is length minus weight: a 30 in, 20 oz bat is a -10. A bigger drop number means a lighter bat for its length. Younger players use -10 to -13; USSSA 13U is usually capped at -5; high school and college are -3. Tip: Check the drop your league allows before you look at anything else. |
| Barrel | longer extended barrelWhat this meansA big barrel (about 2.56 in and up) gives the most hitting surface. Its size does not decide the balance: some big-barrel bats are balanced. |
| Handle | standard handleWhat this meansAbout 0.93 to 0.96 in. The usual choice: enough whip, enough strength. Tip: Most players never need to think about this one. |
| Knob | TaperedWhat this meansA cone-shaped transition from handle to knob, somewhere between standard and flared. |
| Lengths | 29, 30, 31, 32 in |
| Barrel end | Cupped |
| Finishes | Gloss black barrel; gloss grey handle |
| Warranty | 90 Day Limited Warranty against manufacturers defect |
| Availability | In stock |
