Can Bicycle Spokes Be Shortened?

Yes, bicycle spokes can be shortened, though it is not a standard practice and depends on various factors. Specialty engineering services can certainly accomplish this task, but whether it is practical or necessary is another matter that requires consideration.

Replacing a 36 Hole Solid Hub with a Larger Fixed Hub

When considering the replacement of a 36 hole solid hub with a larger fixed hub, one must address the question of whether new spokes are required. The answer often points to the necessity of acquiring new spokes, especially if you are experiencing the same scenario.

Practical Considerations

Practically, cutting and using the same number of spokes as the original setup is not a viable option. There are several spoke patterns available, each with its own spoke length. However, these patterns often do not utilize the same number of spokes as the original. Additionally, a 36-hole rim might not be compatible with all possible spoke patterns. Therefore, it is advisable to use a different number of spokes and a different pattern to match the new hub size.

Wheel Size Considerations

The term 'larger size wheel' is ambiguous. Are you switching between a 700 and a 27-inch wheel, or are you merely changing to a wider rim? Bicycle spokes come in various lengths, and you can easily find the right size at a bicycle shop. It is important to ensure the spokes you use are compatible with the new hub and rim configuration.

Reliability and Safety Concerns

It is generally not advisable to rebuild a wheel with old spokes, even if you are considering cutting and threading them. Old spokes can have unknown durability and may not provide the reliability you need in your cycling setup. Many bike shops can cut and thread spokes, but it is crucial to ensure they meet the necessary standards for strength and reliability.

Threader Tool Issues

While spoke threader tools exist, they come with their own challenges. First, spoke threads are extruded, not cut, which means using a threader tool can compromise the spoke's strength. Second, extruded spokes all stop at the same point, which is beneficial when building a wheel. Threading spokes may negate this consistency. Additionally, used spokes are often not suitable for rethreading due to potential fatigue, which can lead to breakage.

Solution: Buying New Spokes

The best course of action is to buy new spokes in the correct size. This ensures that your new hub and rim setup will be reliable, safe, and perform optimally. While it might seem more expensive, the peace of mind and performance benefits are well worth the investment.
