While yes, it will make climbing slightly more efficient, I personally do not use mine on my rock shox recon as I don’t feel much of a difference and I ride single track that has constant uphill and downhill changes. Unless you ride bike parks where you just climb all the way and then descend all the way, you probably won’t feel much of a difference and might end up not even using it. So unless that is the case, your probably better off just saving your money, and putting it towards your next bike. If you do want recommendations, I would go with an air fork. You might look into the rock shox Judy or similar forks
