Speedfill Hydration System

Is anybody using this for long course and what is your take on it ?

I currently use 2 behind the seat and 2 on down/seat tubes.

  • I used it for IMWI last year. I put all of the infinit I needed for the entire day in it and it worked great. The one modification I made is I did not use the straw holder that had it sticking up in the air. Instead I tucked it between my arms in the aero bars and only lifted it to drink, since having the straw in the air all day is not very aero.

    For water I just used an aero bottle and refilled it at aid stations.
  • @Matt - is there any course you wouldn't use the speedfill? Thinking a hilly HIM perhaps; weight of a full system etc. Also, you mentioned aerobottle, on the frame or horizontal between the bars?
  • @Matt,

    Have you used an Aerodrink in the past? Do you really think there is a tangible benefit of a frame mounted system like this, either in terms of aero or functional convience, over that of a forward aero-bottle system like Aerodrink?

    The aerodynamics certainly aren't there quite yet, but I'm curious when when/if we'll see something converging the type of aero nosecones used on the Shiv and the new Trinity Advanced with functional hydration systems.

     

     

  • The nice thing about the speedfill is that it is soo easy to refil and no sloshing liquid all over your handlebars and arms. As for weight, IF you use the nutrition/fluids provided by the race then you only need a small amount in the speedfill to start and then you just keep adding nutrition as you hit aid stations.

    For IMWis I had the speedfill for my water only and a profile bottle between my aerobars with my Carbopro in it. I had 1200 cals there and slipped a baggie over the top (popping the straw through the baggie) to hold the yellow mesh and carbopro in the bottle with zero mess during the ride. Then I only added enough water to my speedfil during the race as I saw need for. Therefore I didn't carry any extra weight on the bike in the way of fluids.

  • At most the speedfil adds 24oz of liquid and a few grams for the bottle of weight. Hardly anything if you ask me. Plus the fact that I never stopped once during the entire ride easily makes up for that, compared to folks that stop at special needs to get another bottle.  Also, I had zero risk of dropping or missing a bottle with my nutrition, it was filled and ready to go before the race started.

    I used the speedfil in addition to an aero drink last year and the combo worked great.  My bike had a round headtube and I felt the aerodrink at lest didn't make things anyworse and it is easy to fill and use.

    That said, I don't plan to use an aerodrink this year for two reasons:  my ne bike has a aero headtube already so blocking it doesn't make sense and more importantly the aerodrink hits the top of my front wheel.  I'm planning to use a horizontal bottle between the aerobars instead, which is what I trained with all of last year.



    As far as aero benifits goe, without a wind tunnel we will never know, so all I can do is use common sense. Therefore I get as much out of the wind as possible, i.e. no straws sticking up, no extra bottles, nothing on the back of my seat post, etc. All these little details are probably only worth seconds over the entire day, but to me seconds mean something.

     

  • Makes sense to me Matt - now, anyone got any deals on the thing?! Kinda pricey for a bottle n' a bit of tubing isn't it? Putting a price on effective hydration! Yikes! :-)
  • @ Matt - how did you monitor how many calories per hour you were getting? I put all my infinit in a clear bottle and draw a few lines on it. That way I know how much I should've drank from the bottle every 14 miles. Seems like it would be hard to do that with the speedfil.
  • @Branan - I simply took two sips every 15 minutes and chased it with as much water as I wanted. I started this 30 minutes into the ride and my goal was to finish the infinit 30 minutes before I finished the bike. It took me a little bit of trial and error to figure it out, but that is what the race rehearsals are for.

    @David - i don't know of any deals, I got mine from either trisports.com or all3sports.com last year when they had a 15% off coupon.
  • The Speedfill may be a moot point for me anyway come to think of it, I ride a Felt B12, as with the rest of the Felt B-series I only have a bottle mount point on my seat tube rather than on my down tube. I'm not sure if you could place a speedfill on your seat tube, but every picture I see is down tube mounted.

    I currently ride with an X-lab carbon wing behind my seat where I can carry two bottles and my aerodrink up front. IMWI will be my first Iron distance race, but I have had no problems in HIM with carrying a single fuel bottle (last year it was Perpetuem/HEED mix, this year thinking about going with EFS) and then water in my aerodrink. I would top off my Aerodrink with fresh water at aid stations and immediatley dump the empty. If I really wanted I could always pick up up to two extra bottles from the aid station to store in the empty spots behind my seat or on the downtube.

    All that being said, the aerodrink splashing all over me bugs the crap out of me. I only made the mistake of putting anything other than water in there once, giant sticky mess.

  • splashing is a huge annoyance with the aerobar systems.  I've gone to the bontrager one for that reason.  Need to put some sort of bite valve on the straw, but spash from the fill hole is a non-issue with it.

     

  • I have never had splashing issue with the PD aero bottle other than when it is completely full. I just put the yellow sponge in sideways so it stays in place and then the black cap on top.

    At each aid station I take a gulp or two of water first, then put the rest in the bottle and take a gulp from it. This way it isn't completely full and I don't get splashed.
  • @Mike - I've been looking at the Bonty aero system - is there a way to mount the holder (vertically) higher up, such as Lieto does/did? It that way you keep the headtube area clean & the bottle vertical between your arms.
    OK, from a newbie perspective, what does concern me is nutters grabbing bottles at the feed stations, think I'd rather stay as clear as posible unless I have to. i.e. reason why I'm not keen on the horizontal bottle idea, simple as it is. Again, newbie perspective so may be a load of rubbish! :-)

    @ Trevor - I have only mounts on the seat tube also - not sure if the speedfill would work; perhaps but may act as a windbreak!
  • I've never liked the aerobottles between my bars - seems to give me stomach problems.

    I usuall use 2 bottles of water behind my seat and one bottle of concentrated Infinit on my downtube.  This year I'm going to try the speedfil for water, and a bottle horizontal between my aerobars.  I know most people do it the other way around, but I figured with a clear bottle for the infinit I can monitor how much I'm getting.  Plus I don't have to get the infinit out of the speedfil.  Just a thought.

  • @ Trevor...I ride a p2k, so same brazeons...contacted the Speedfill people and they have an adaptor for bikes that only have brazeons on the seat tube.  I am going to give it a try...  Dave

  • Here we go, the speedfill seat-tube adapter kit.

    Thinking also that if I'm going to be lugging liquid around I'd much rather it was low & central on the bike - may sound silly but perhaps not when you seat is 82cm from BB high! Good to keep that centre of gravity low especially for my UK 70.3 'twisty-road fest' in June!

  • @Matt - I'm back around at this again(!) - mainly due to researching more about on bike nutrition - think I'll definitely go with a speedfill for full IM however wondered what you felt about using it for HIM, especially a hilly one? Thinking about lugging too much weight around again - maybe that's a silly perspective to have? Guess i don't need to fill the speedfill to max in any case, just have enough drink for the HIM distance.
    How aero is it, any pics of your bike with the unit attached?
    Thanks Matt!

    I only use the speedfil for IM and the 2 IM Race Simulations.  I agree, for me it was a little overkill for a HIM.... I just use an aero shapped bottle on my downtube for HIM.

    Here are a few pictures from IMWI last year:

     

  • Thanks Matt - looks good - I'll wait until to I start my IM training & just rock tow 750ml bottles for now, 1 horizontal on the bars.

    Ingenious use of the seat post Matt, good tip - also, do you get a good FM signal on that FD cable? :-)
  • I just got the Speedfil but haven't ridden with it yet. The Speedfil is 40 oz, correct? My usual practice has been to ride with two 20 oz bottles so it's even for me.

    I'm not quite sure how I'm going to use this - if I'm going to put Infinit in the Speedfil or carry a concentrated feed bottle. I have three months to experiment!
  • Matt- Tell me about everything around your seatpost!

    Matt- Tell me about everything around your seatpost!





     

    There isn't much there.  One tube of the fix-a-flat stuff in the front and then my race number to hold it to the seat post.  IT creates a decently aero shape though with a round leading edge, the round smoothing out the transition, and then the back edge of the seatpost being a good trailing edge.

    The idea came from StinkyHelmet. 

    @David...funny, but I actually left the FD cable long on purepose because then I can bend it back and out of the way and not get hit in the leg with it.  Plus I mess with my cabling and position way too much and a little extra cable is always good to have.  I could have went a little shorter and will next time around.

  • Matt,

    What is that below your seat in front of the seatpost?

    V
  • I have the speedfill system and 2 bottles behind the seat, you can argue the weight if you want, but for my slow butt, the nutrition control outweighs the weight gain. Essentially its like carrying 4 bottles of fluid.

    The Fix- a-flat stuff ....

     

  • @Matt: Where do you mount your Edge.. With the Profill bertween the bars I am having a tough time with a location that I can see it and not have it interfere with something else? Dave
  • I used three different setups last year:

    • Computer on the stem, horizontal bottle on the bars - worked well, but I had to look
    • horizontal bottle on the stem/bars, computer on PD computer mount up front
    • PD aero bottle, computer on PD computer mount up front (race setup)

    This year I'm almost positive I will only use the horizontal bottle in both training and racing.  I'm also going to try and put the computer on the stem and bottle on the bars as I am now much better at feeling how many watts I am pushing.  last year I didn't trust myself and wanted the numbers right in my face.

    Here are some pictures I was able to dig up...

  • @Matt-

    I like the bent straw in PD. Very clever!

    I run a Cervelo, so I also have a supposedly nice front end of the bike and I wonder about the PD Bottle. That said, the whole convenience of just leaning down and drinking seems to be great. I'd be willing to experiment with a horizontal-mounted bottle like you have, but do you run into a lot more awkwardness in taking the bottle off, drinking from it, and putting it back than it's worth? Maybe I'm wrong, but it seems like it would be a lot easier to remain in position drinking out of the PD than any time you have to hold a bottle in your hand. How have you found it? I know you won't have data, but you must have impressions.

    My setup has been calories in a traditional bottle on the down tube and water in the PD. Water picked up on course and squeezed into the PD. You must do the reverse, refilling the Speedfill.
  • My general problem is that on such a small bike I simply don't have enough realestate to put all the crap!! Fairly positive the speedfill won't fit my frame (the Arundle bottle barely does) and my aerobars just aren't quite long enough for the PD bottle and the PT computer. I'm going to play with using my Garmin 310XT on my wrist this summer to see how that works out. And although I have a really nice aero front end too on the Felt B2, I'd rather avoid messing up the air behind me with a rear mount system. So PD up front is likely where I'll end up.

    Matt- do you recall where you got your bento box? The one I have won't fit on the Felt with the aero fork and the inner-frame routed cabling. Looks like you might have the same issue with a standard bento box- so where did you find one that fit?
  • @William - it's completely personal preference on what is easier. The horizontal bottle was a little weird at first, but I got used to it quickly and it is REALLY easy to swap at aidstations without splashing, spilling, or crashing. The argon did not have a very areo leading edge so my assumption (very big one) was the profile bottle actually helped. The Orbea Ordu I'm riding this year does have a aero headtube and therefore I'm sticking with the horizontal bottle. All in all, it we are probably spliting hairs here and your race number in the wind will probably have just as much drag as the difference in the setups. Try both and see what you like more.

    @Nemo - it's the fuelbult aero bento box. You can get it right from their website and I think P even posted a discount in the wiki. the reason i like it is that the zipper is on top were as most bento boxes had velcro on the sides that cut my knees up.
