I know some will say this product is dumb because you have a bike and actually ride it hard, it will get scratched at some point. However, this was a GREAT purchase for my new carbon gravel frame. I searched every other option because I thought I could find something better and cheaper and ended up buying this in the end. It's a great product, very easy to install, and you can barely see it on my new Alchemy Lycos frame. Cleans easy and was actually quite fun to put on. Lots of options for install and would put on my next new bike too.
SRAM front and rear derailleurs don't come with batteries most of the time. I converted my TT bike from mechanical to wireless shifting and needed one more battery to complete the set up. It's nice that these are standard and can be moved between bikes so you don't need to have a bunch of them. I have another one on my AXS XPLR dropper post that I move to the TT Bike when I'm going to ride it now, or back when I'm using the gravel bike.
I works. I rotate it in with my other two batteries on the bike, so have only used it for one cycle. It is a little expensive for such a small battery and just in case spare battery. Wireless shifting is so much better. I have it for my 2x12 SRAM rival wireless. During the season of 2023 I was on two different rides where another rider had to cut their ride short due to a dead SRAM derailler battery. I can't remember that last time a cable broke on a ride However it did happen to me a couple of years ago, but was able to mod it to get me home.
Very expensive for a battery, but this is the price most anywhere! But now to the review. Could you get by with only the two? Sure......if your rear goes out you can swap the front which is needed less and one can have a gear range to finish a ride. However, having both derailleurs working with a spare or even two is best for very long rides. Hold do they hold a charge and perform? Well, my usual 20 mile rides daily I get up to 7-8 rides of changing the rear anywhere from 180-250 times. The front, I get longer on but only change typical 10 times per ride. This kind of shows the battery life to those wondering. I see a lot of post on broken connectors and tabs??? I wonder sometimes if people change in haste by "monkey fisting" these things rather than taking your time which in all reality is like 5 seconds to change out??? So are they worth it? Yes......unfortunately you have to drop $60 on something SRAM has to produce these at maybe $5 each and in all reality should only be like $20 tops!
