Spoke nipples aren’t reverse threaded, but when you’re turning them, it seems that way because you’re turning them from the bottom, not the top like you would a regular nut or bolt. … To avoid this, always loosen every other spoke the same amount you tighten the others.
Which way do bike spokes turn?
Note that the spokes have nut-like devices at the rim called nipples. When viewed from above, nipples are turned clockwise with the spoke wrench to tighten spoke tension and counterclockwise to loosen it. To ensure that you turn the nipple the correct way, always rotate the wheel to bring the nipple to the top first.
What thread is a bicycle spoke?
According to the Park Tool website, the typical 2mm spoke has a 2.2mmx56TPI thread. This converts to a 2.2mmx0.
What tension should my spokes be?
The recommended tension for spokes in bicycle wheels can be as low as 80 Kilograms force (Kfg) and as high as 230 Kilograms force. As a rule of thumb, it is best to set tension as high as the weakest link in the system will allow, which for a bicycle wheel is usually the rim.
Can you over tighten bike spokes?
It is rare for spokes to be too tight, but it is very common for them to be too loose. … In this situation, tightening just the loose spokes will cause the wheel to bend even more, in the same direction. Instead, the rim should be bent back into shape first.
Can you tighten spokes with pliers?
Registered. I carry a small locking pliers. A very helpful tool anyway. Good for spoke nipples, just takes a bit of care not to crush them while tightening.
Are loose spokes dangerous?
Never ride with a loose spoke. The friction created will cause the rider to burst into flames and may even cause the Earth to slip off it’s axis.
What is nominal thread size?
Thread sizes are given in nominal sizes, not in the actual measurement. The exact measurement is slightly below the named or nominal size. For example, a 6mm bolt may measure 5.8mm or 5.9mm, but it is called 6mm bolt. It is also common to use “M” before the bolt size, such as M6 for a 6mm bolt.
How do you measure spoke nipples?
The best method to determine the correct spoke wrench size is to use a caliper and measure the nipple across the wrench flats. It is important to know that the diameter, or so called “gauge”, of the spoke does not determine the spoke wrench size.
How much does it cost to tighten spokes?
To make sure you tighten the right amount we suggest using a spoke torque wrench set at about 48 inch-pounds. To make sure you tighten the right way, follow this pattern: Start at the rim lock and tighten the first spoke. Then skip two nipples and tighten the third.
How true should a bike wheel be?
3 Answers. If your wheel is trued (lateral movement) to within 0.5mm it is considered good. Same 0.5mm tolerance for the roundness of the wheel. … And finally the wheel will go out of true with use especially during the first few rides, so check it after a couple of months.
Why do spokes come loose?
Since the spokes of a properly built wheel are under a high level of tension, there is no “play” in the threads. … For the spokes to loosen, the load would have to deform the rim enough to relieve the spoke of all tension so that the nipple can turn.
What is truing a wheel?
The typical bicycle wheel is composed of a rim suspended with tensioned spokes around a center hub. … Changes to spoke tension will pull on the rim and affect its true. This process is called “truing”. Truing is occasionally needed to keep the rim running straight as it spins between the brake pads.
