Zefal Bicycle Air Profil Road Frame Pump - Answered Questions & Fixed issues

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.

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.

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.

There is no serial number database for those bikes https://www.google.com/search?q=white+super+chief+bicycle+date+of+manufacture https://www.google.com/search?q=white%27s+super+chief ..

serial number is 12900243GT m one. Can anyone tell me the year?

clean your garage and you will have it. or try bike shops.

If your bicycle doesn't have mechanical gears, the issue might be related to the freewheel or cassette, depending on your bike's specific setup.

Standard WD40 is just a 'quick fix' as it isn't an actual oil unless the can is clearly labelled as "Bike All Condition Lubricant". It'll be best to buy a proper light oil like 3in1, 151 Super oil or an actual chain lube. This 'clickey' noise. Is it random and happening every so often or is it a constant, regular click that changes with the speed your pedalling at? Check for slack in the chain. as you wiggle the chain up and down there should only be about a centimetre of movement in the chain. If it's too slack or too tight it can make strange noises. Check the axle bolts and nuts to make sure they're not loose. Check the wheel is mounted straight. If it's turned left or right the chain will 'skip' as it's slightly missing the cog teeth on the wheel. Use the frame at the rear end of the wheel as reference and measure how far the side of the wheel is from the frame on both sides. It should be about the same both sides.

No, not easily, but you could fix it possibly? https://www.google.com/search?q=edge+491+electromagnetic+bike ..

It is a very standard bike, this manual will do just fine. It has normal caliper brakes. https://images-na.ssl-images-amazon.com/images/I/C1i84aprpSS.pdf https://bikeindex.org/bikes/1022118 https://www.google.com/search?q=Nishiki+Manitoba+manual

You are using the wrong terms although 'pedals' is correct. The 'shaft' is called a 'crank' or a 'crankset'. https://www.google.com/search?q=Nishiki+Tamarack+crankset+and+pedals General Parts https://www.google.com/search?q=Nishiki+Tamarack+parts+website ..

That depends on what you are using it for. Obviously, if you are dirt biking, you should use a dirt bike, and otherwise use a street bike. Start out with what you are going to use the most - dirt (freestyle) or street racing.
