Dnes som si dal cistit retaz do ultrazvukovej paradnej pracky. Asi ma to zachranilo od problemu, a mozno aj bolestiveho 
No to bude ten dovod preco su tie spojky jednorazove, alias nesmu sa otvarat a znova zatvarat. Aby to nedopadlo hentak.
Otazka je ako dlho pouzivas a rozpajas verzie pre 11sp a viac.
Ja tiez so spojkami nemam dlhodobo ziadny problem, ale nad 9sp som sa este nedostal
Do 9sp boli urcite na opakovane pouzitie, vyssie neviem.
12sp ma v popise toto:
According to the manufacturer, SRAM chain locks are only intended for single use!

“Our 10- and 11-speed PowerLocks are one-time use only, because as they are removed, there’s enough deformation at the interface where the pin clicks into the plate that a second install will not be as secure. The potential failure mode is the PowerLock opening on its own when the chain goes slack. You can hear and feel that on initial install, the PowerLock installs with a loud click, and requires a tool to re-open. But on subsequent installations, it installs silently and with no effort, and can be re-opened by hand.”

Cena rýchlospojky je dosť banálna na to, aby sa riešilo jej viacnásobné použitie... Si skromne myslim teda... 
Tecka Samozrejme mozes ich pouzivat ako ches. Ale to nemeni nic na tom, ze su jednorazove. https://cdn.sram.com/sites/default/files/techdocs/95-2415-004-000_rev_b_cassettes_and_chains.pdf
