PRECISION PRO Drive Side Maintenance Kit

Glad they make a replacement, but shouldn’t be necessary. My drive side battery cover is cracking despite being extremely careful when changing the battery not to over tighten. At least mine lasted almost 3 years before completely falling apart where others have had issues much sooner.

I am writing same as everyone else to help and protect people looking at buying these power meters, it is really a great product just wish that the drive side cover could last longer mine as broken into pieces and now I am left looking around for a spare cover which is super difficult to find. I am stuck now and at the mercy of your response on what I need to do now ! DURA ACE 9100

Two units broke in one year.

Exactly the same way as specified in the other replies.

Shame for a product this expensive...

These battery covers (right side) are pretty poor to be honest, although I'm gonna have to buy ANOTHER!
I've got two dual meters(ultegra & 105), and I'm careful using cleaning products around them when cleaning my bikes, yet that's two that have disintegrated while changing batteries. Even one of the cases has cracked.

Love 4iiii products otherwise.

Within 2 battery replacements the cap disintegrated. Replacement is sold out. Bad product for this price!
