## Questions & Answers

**Q: Can this be used on a rockshox monarch debonair?**
A: I don't think so, page 33 of the SRAM service guide states you can use 15W oil around the top of the air can as a lubricant, but recommends using 3WT or 7WT in the service. Perhaps ask the guys at TF Tuned, they're normally very knowledgeable and get back to pretty quickly. http://www.tftuned.com/contact-us

### ⭐⭐⭐⭐⭐ On time

Quality stuff

### ⭐⭐⭐⭐⭐ Good official product
*by A***Y on 30 June 2025*

Cheapest I could find, I bought for rockshox forks so can’t go wrong

### ⭐⭐⭐⭐⭐ It's oily - it does what it's supposed to perfectly
*by S***E on 25 June 2025*

I actually got this as an alternative to forkboost for lubing the stanchions on my cheap air fork. For this purpose I'd get a lighter weight oil next time but for what this is and the price of it I can't complain. I would imagine it's perfect for it's intended purpose of going inside the fork instead of external lubing like I'm using it. 5/5 good quality suspension oil - maybe get something lighter or less viscous for oiling stanchions
