The 450 Deluxe is a another great addition to the Fidlock family. It fits on my Scalpel under the shock where most other bottles will not fit. The dirt cap cover is fantastic and the bottles new shape makes it even easier to center and click in and out. Awesome product!
First ride with the Fidlock and I took it up to Curt Gowdy State Park in WY. It stayed put even on the gnarliest descents. I never worried about it falling off and it didn't get in the way. I've been looking for a solution since purchasing my Santa Cruz Hightower LT in 2018 and finally found this setup. So far, it is the only one that does not rub the shock. I am going to try the next bottle up. My only con is that the bottle cap/lid seems a little flimsy. Other than that, I am happy and hopefully will be purchasing additional bottles.
