there is a little switch looking thing that has to be lifted up from the pump then insert the valve into the bike pump and then puch the switch/lever back down and start pumping then to take off lift lever and quickly take pump off valve otherwise you will lose air you just put into tire
After a call to the customer service people who were more confused than I was, I figured out how to mount the bracket to the handle bar. Believe it or not the Zefal guys did not have an instruction manual on the product they sell. So here is how it works...
You have to run the hard plastic strap around the handle bar and push it into a gap between the plastic nut . It's such a small gap that you will have award time finding it. Once you tighten the plastic nut the strap will advance slowly until the end will come appear on the other side. That's all there is to it.
Now why the heck could they not put a picture of this on the box? Perhaps job security for the Zefal guys?
Linda,
I was having problems with the installation also, but my husband finally figured it out. Just start the end of the strap at the screw, as you tighten the screw with the Allen wrench it will thread the end thru and will get tighter around the post of the bike. It works perfectly and now I can use the GPS on my iPhone to record my rides. Hope this helps!
Place the end of the air hose nozzle from the pump on the tire valve. Flip the lever on the side of the air nozzle straight up to lock the nozzle to the tire valve.
Hold the cylinder in one hand. Grab the end of the pump by its handle. If the handle flips up, flip it up and turn it sideways and let the handle slip into your palm. The stem of the handle should be extended between your middle finger and your ring finger.
Pull the handle straight out. You will hear a slight hiss as the air is pulled into the bottom cylinder and air is expelled out down the hose at the same time.
Push down on the handle to expel the air into the hose from the bottom of the cylinder. Continue pushing and pulling up on the handle as you hold the pump in your hands until the tire is firm to the touch. Remove the air nozzle from the tire valve.
Place a tire-pressure gauge on the valve to check the pressure. Continue pumping and checking the tire to inflate it to the recommended pressure that is marked on the side of the tire.
You don't have to "set the pressure", that knob is just for your own reference.
Most problems of this sort are due to not getting a good seal with the tire nozzle. Here are some steps to help you along.
1. put the bike on a flat surface 2. spin the wheel so the nozzle is facing upward 3. put the pump end on the nozzle with the lever down (this is a common mistake as older pumps had to start with the lever up) 4. Push the end down on the nozzle and pull the lever up 5. If you hear air escaping, then hold the pump end on the nozzle for the first few pumps. 6. pump it up till its a bit hard but be careful you can pop it.

The needle part for blowing up basketballs and the like simply unscrews from the bike tire part. Depending on the type of tire you have, you might have to get an adapter. If it looks like your car tire stem, it's called a Schraeder valve, and you should be all set. If it is thinner and has a tip that you unscrew, it is called a Presta valve, and you may or may not need an adapter depending on your pump.
If it is a dedicated presta pump, there should be a threaded cap on the head where it attaches to the valve stem - it has a hole through it to allow the stem through. Tighten that stem slightly and it should compress the rubber enough to hold on. But don't tighten too much or it will be hard to get off.
The head holds on with a rubber donut under that cap. By tightening the cap, the donut gets compressed and closes the hole tighter.
Let's hope you didn't force it and snap the plastic point off.
Most Zefal pumps come with a reversible head that can adapt to either Presta or Schreader (like on cars). You unscrew the barrel at the working end of the valve, carefully tap out the rubber cylinder and the plastic internal piece behind it.
Insert the plastic piece in either of two ways. Pointy part Out (for Schrader) or just a round opening Out (for Presta). Rotate the rubber piece correspondingly to show the large opening for Schrader or the smaller opening for Presta and place it inside the valve over the plastic piece. Screw the knurled barrel on tightly.
If your pump is not double sided (which the one in the picture looks like) the rubber valve can be reversed very easily by unscrewing the outer cap where you usually insert the valve and turning the little rubber valve around before screwing the outer cap back on.
yea! i remember toeclips and straps and tightening them at 50kmh just before the sprint... bit dodgy. it's just that they really can become stuck as there is a beartrap system that locks on to the leather strap and they are outdated by the new spd's and cleat lock systems. You can of course use them but check the pedal width to make sure your knees are not pronated outward from the frame as all new systems have a narrower bottom bracket. The Spd's will be fine as will Candy's, i use both
Below is an online video on how to adjust your gears. Your issue could be a number of things:
- cable is seized or full of gunk- make sure that it is cleaned out and lubed before you try to adjust your deraileur.
- check the two lockout screws on the deraileur - one handles the high and other handles the low gear. Their purpose is to make sure the chain doent fall into the spokes as well as the frame when reaching the extreme ends of the shift.
