Profile DesignFc25 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.

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.

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.

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.

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

Terrible design, takes more energy getting water out than it is worth. Spent months trying to get used to the thing and making adjustments to see if I could get it to work decently and went with bottles for my 1/2 Ironman because this thing wasn’t useful.

Les attaches ne tiennent pas sur le velo .. acheté en decembre et malheureusement utilisé a l’eté donc plus possible de retourner malgré que l’article ne fonctionne pas … achetez ailleur !

Une des vis a foiré dommage(a force de la changer de positionMais ceci étant et après une bidouille ça marche niquel

Very good for drinking in the tuck but prone to leaking.I bought this to use during a half ironman. It was easy to install and is straightforward to use, enabling you to drink while holding your tucked position on the aero bars. I can't speak for the aerodynamics but it certainly looks the part. The clip to tuck the straw out the way when not drinking is particularly useful otherwise it would be very annoying waving around in front of your face the whole time. It is simple to refill on the go, you can do this one handed so you can keep riding while you pour in drink from a second bottle (I have a bottle cage mounted behind my saddle).The nutrition compartment at the back is a mixed bag. It's quite small and as it's only got an elastic band over the top, the contents try to jump out whenever you hit a bump or rough patch of road. I used a small strip of card over the top and under the elastic to keep my cliff bloc chews from tumbling out, a simple hinged lid would solve this. The only other problem is that it is prone to leaking. The grommet around the straw leaks quite a lot. I spoke to a Profile Design rep at the race expo who stated they were aware of this and a new grommet making a better deal was on its way and would be available as a spare part for a few pence. The bite valve also leaked a bit and although I didn't really notice during the race, afterwards I found my bike covered in drops of sticky energy drink which is again pretty annoying. Hopefully another simple fix will be on its way.All in all, a very stylish solution to drinking on a Tri bike, but the leaks are a real nuisance at this price.

最高の製品だと思います。DHバーもPROFILE DESIGNなので、フィッティングもばっちり。路面が荒くてもびくともしませんでした。ストローも秀逸で、歯で嚙まないと吸えないので漏れもありません。中身が無くなったら、補充用のボトルをそのまま投入口に差し込み、スクイーズすると簡単に補充できました(走行中でも)。やはり、DHバーポジションを崩すことなくスピードを維持したまま、少しづつ定期的に水分補給できるのは大きなメリットがあります。先日の大会で、後半水が無くなってしまい、ランで脱水症状になってしまい痛い目にあいました。なんとかしないと、と思いフロントハイドレーション購入を決意。今となっては、なんでもっと早く導入しなかったんだろう、と思います。中身には、経口補水液を入れています。これも激しいトライアスロンには最適です。足攣りもなくなりましたので、安心してBikeを飛ばし、Runにも繋げられそうです。次の大会が楽しみです。

Not sure if ProDesign fired all their senior engineers, but changing the design so that the unit is held in place with a single rubber band is not a great idea. Without a doubt, a bad investment. We have to hold it in place with own rubber bands. Not at all secure.
