Profile Aero Drinks System
in General Chat
I was wondering if anyone knows anywhere you can get a straw for one of the profile aero drinks bottle.
My girlfriend has lost mine after tidying up and I don't really want to buy a whole new system just for the straw.

only £3
to be fair though, brewers plastic tubing tastes god awful for the first few times you use it, but if the drink is flavoured then its ok. i made my own aero-bar bottle arrangement with an sis water bottle, some brewers tube and some plastic discs cut on the office laser cutter. it's not posh but does a job.
Re the aero bottle - there was something advertised in 220 this month (or last) which has the bottle in its notmal place on the frame with a long tube - nivagh are you selling these things?
I'd better make it in red.
There is an online calculator at http://www.efunda.com/formulae/fluids/c ... iction.cfm
I wouldn't recommend rear mounting either, could get a bit annoying if you end up siphoning you drink out and can't stop it.
Aim of game, provide hydration without have to get out of aero position and fiddle with bottle and cage.
Initial plan was to put 500ml bottle on bike in water cage, use hollowed out top of water bottle mouthpiece as output for pillaged bladder pack feeder tube with bite on/off flow system, so after initial priming of tube the bite on/off will stop the liquid flowing back down tube into bottle. Problems, bottle needs to be airtight otherwise air will escape allowing liquid back down tube and meaning it has to be primed every time.
Talking to motorbike fundi, suggested just going the whole hog, do away with water bottle and cage. Buy 5.99 bladder and tube, go to B&Q (other hardware stores available) by carbon fiber and epoxy as per the great http://sheldonbrown.com/rinard/carbonqa.htm. apparantly it's easy to build a small well at bottom of down and seat tube, house £5.99 bladder pack and have feeder tube with bite on/off shutoff system as well. This gets around air tight issue as bladder and tube is designed for this usage, added benefit of have lower center of gravity, and if I going to be bothered to worry about 50mm deep rims when I only avg 35km/h then may as well think aero disruption with regards to bottles.
Essentially I am not going to be winning any IM's or in fact any other distance, but the whole bike thing is a bit of a boy's fiddling thing anyway (not that kind) so if it saves me sitting up, fiddling with bottle out of cage, gulping as much as I can in 1 go because can't be bothered to do the whole operation too many times and then crashing into something because the bottle won't go back into the cage. Then I figure the fun I will have sticking bits of my fingers together with expoxy and carbon will be well worth it.
If anyone has done this before, do let me know as I suspect I am going to get shouted at for spending too much time in the garage with a toy instead of proper housework, or quality time together with the good lady.
I have seen guys with 4 bottles; bottles on the seat tube, down tube and 2 on a behind seat carrier. A long distance event is littered with bottles dropped or 'pinged' from behind seat carriers so yep something to be considered.
How big is the bladder? Considerations; sweat rate average 1l hour, 1l water = 1kg
Anything over 2hours or so and you need to think about refilling if a 2l bag.
My solution on a long distance event - aero bottle between aero bars, concentrated 'syrup' of energy/electrolyte drink in bottle on down tube. Approach feed station one squirt of syrup into empty/depleted aero bottle, pick up water or energy drink (usually v diluted), empty into aero bottle, dump empty bottle.
Good luck and post some pics
