Fc25 Hydration System with Bite Valve, White, 25oz

It's pretty great. Kind of a pain in the butt to clean, you'll probably want to only put water in this, and keep liquid fuel in regular cage bottles; that's what I did. In keeping with tradition, the strap continues to be a fair hassle. I did get the model with the red silicone strap, and it is marginally easier than the old style velcro strap on the blade style bottles. It's still not something you're going to want to mess with while racing. The refilling flaps are a little too stiff. If you use regular cycling bottle with the push/pull spout, the flaps could close the bottle on you. You'll want to use something much more rigid, like those camelback bottles, or a screw top water bottle (but not those super flimsy ones that are made with plastic so thin they explode when you try to open them). I took the computer mount off of mine, since I only wear a tri watch. Which is really nice, that the mount is optional. I do like using the little bento box for putting things in, like my car keys while on a training ride! I haven't used it for gels (I don't like gels :P )

This thing sounds/looks good in theory, but is a terrible design. First off, the flexible straw is a no go, you look like a nursing home patient with your tongue out hunting for your straw while going down the road, plus you have to bite it to get any fluid out. Next, the storage compartment is useless, both rides I lost my gels, i mean they’re gels, nothing heavy. 3rd, the splash guards are minimally effective and vibrate loose and fall off. But the worst part is the red band that secures the tank to the mount, it is a joke. After it fell off a 2nd time on my ride today I pocketed my gps unit and chucked the rest in a nearby dumpster. Don’t waste your time on this one, use your pockets for nutrition and get a simpler system for your hydration.

The little strap is hard to buckle and popped off. With a little rattling from normal road conditions, it fell off and gave me a flat when I ran it over. I don't like the fastening design.

Folks be careful tightening the bar hardware; doesn’t need to be overly tight or it will strip the housing. Also the orange retaining strap is difficult to fully lock in my set up, but it seems very stable w/o the double locking mechanism. Bit difficult to clean, but I stick with just water and supplement with chews. All that said, bottle setup is exactly what I was looking for in shorter ride hydration. Customer service is stellar, had a question re the bite stem and Profile replied within a day with spot on info. Great product.

Good design but not much of an improvement over the last design. The way the bottle attaches to the holder is still very hard to manipulate. That’s the part that they need to fix.

I like the filler valve. Same as the FC-35 valve.

I was really debating on whether to buy this or not. I really wish a hadn't. The bottle leaked heavily anywhere close to half full no way I was able to fill the thing without soaking by bike and legs with my sports during. Not insulated at all, liquids quickly become warm. Lastly, a month into riding with this thing the screw holding the straw down fell off and now there is a gapping hole on top I'm going to have to find out how to cover if I want to try to continue using it. Maybe worth it for $10, but $80!!! Something that expensive should actually function properly. Just buy the water bottle holder, then you will just need to worry about the quality of your bottle.

This product mounts using zip ties. It does not have the circle mounting clamps as shown in the photos or as told in description.
