Password Recovery Procedure
1.Press Break(CTRL+Break) on the terminal keyboard within 60 seconds of power up in order to put the router into ROMmon.
2.hostname> confreg 0x2142This step bypasses the startup configuration where the passwords are stored.
3.hostname> reset
The router reboots, but ignores the saved configuration.
4.Type no after each setup question, or press Ctrl-C in order to skip the initial setup procedure.
5.hostname> enable
6.hostname# configure memory or copy startup-config running-config
in order to copy the NVRAM into memory.
Warning: Do not type copy running-config startup-config or write. These commands erase your startup configuration.
7.Type show running-config.
The show running-config command shows the configuration of the router. In this configuration, the shutdown command appears under all interfaces, which indicates all interfaces are currently shut down. In addition, the passwords (enable password, enable secret, vty, console passwords) are in either an encrypted or unencrypted format. You can reuse unencrypted passwords. You must change encrypted passwords to a new password.
8.hostname(config)# configure terminal
9.hostname(config)# enable secret 00000
10.Issue the no shutdown command on every interface that you use.
11.hostname(config)# config-register 0x2102
12.hostname# write memory or copy running-config startup-config

Park Tool 變速器吊耳校正規
今兒個來介紹這個
官方連結：Park Tool Derailleur Hanger Alignment Gauge
後變速器是一個平行四邊形的結構，原則上不管在哪個檔位，導輪都應該平行於飛輪。(紅線B)
後變速器是固定在吊耳(勾爪)上的，所以當變速器遭受外力撞擊的時候，吊耳很容易走針，然後就是變速調到死就是不準，或是有異音。
在8、9速的時代因為每片飛輪的間距大，遇到吊耳變形用六角扳手插進去喬一喬，目視檢測多半能搞定。不過現在飛輪一多，越來越精密，靠校正規會比較實際。尤其現在的吊耳多半是鋁合金，不小心喬過頭就斷給你看。
