Flux Customer Service
I own a pair of last year's Flux Feedbacks and I think overall they're awesome bindings. Supremely comfortable, great flex, and the tool-less adjustments are incredibly nice. Unfortunately I encountered a problem with all of the ratchets. Let me qualify this with the fact that I dry off my equipment and take great care of it.
Anyhow, I'm a lightweight rider and from last year up until I encountered the problem, I've used these bindings 15 times. I ride other decks so they weren't used a ton. Fast forward to 4 weeks ago, I took a trip to Whiteface and Killington and rode pretty hard. In the middle of the day 2 days into my trip, all 4 of my ratchets were "creaky" and very difficult to unlatch. Even when my boot isn't in the binding, all 4 ratchets stick really hard and creak like crazy as I'm unlatching them.
I'm not quite sure how they could break down so quickly, but I e-mailed Flux and got a response the next day asking for my home address for ratchet replacements. I offered to send in my ratchets so they could inspect them to improve their product in the event they were defective, but they didn't think that was necessary.
The new ratchets they sent me are the ones on the RK45s/TT30/SE30s. I'm confident these ratchets won't break down. We'll see. I'll post back in this thread at the end of the season. So I've had a great experience with Flux, and they clearly stand behind their products. I offered up a ton of information but they didn't really question me, they were just concerned that I was taken care of.
