Here are my standard Secret Handshake tips for water bottle juggling:
Firstly, if you cannot ride no-handed (road bike only!) it may be that your position on the bike is unbalanced to begin with (cue “bike fit” discussion here). Being balanced on the bike is crucial for everything let alone drinking. For tri bikes it is always best to use a front hydration system with a straw.
Being able to perform simple functions single or no handed is a little bit like patting your head and rubbing your stomach; being able to dig that gel out of your rear pocket without going into a ditch is a good thing. Advanced fun like Putting on a Rain Jacket without Stopping, or unwrapping that slightly brown banana is also a good thing. Safety first, so practicing in the grass is a good way to start.
Oftentimes we ladies are on smaller frames - let’s say 51cm and smaller? Bottle cages that allow you to pull it out to the side, rather than ‘up’ is helpful. Xlab, Topeak, Arundel and a number of other brands make these and offer either Left or Right side open options.
Use “regular” size 21oz/500ml water bottles, not the extra tall ones (750ml or larger than 22oz). You will not die without those 6oz of fluid, but you should have two bottle cages anyway and not rely upon a single 750ml bottle for your needs. Rule of thumb is 600ml of fluid per hour at temperatures up to 75degrees. Add 100ml per hour over 75degrees. This is an old school rule but I am old school…
Lets assume, though, that you are balanced, how to do this eloquently? Especially on smaller frames.
Pro tip#1: Pull from the seat tube cage position, not the down tube cage. I may have to post a video, but to briefely describe how to do this:
Left hand on tops of bar - not on the shifter hoods
Take Right hand and palm down, “backhand” the water bottle and pull straight up and to the right side of the top tube. Dont pull sideways. You are reaching between your knee/leg, running your forearm against the top tube back towards the seat tube…
When you’ve pulled the bottle up enough rotate your wrist so that you have turned the nozzle upside down - bring up to your face and drink!
Practice in the hallway or on a trainer - you should be able to do this without looking down, and keeping your feet moving. Practice practice so that it becomes without thinking. without rubbing head and patting belly…you know, like riding a bike!
