![]() ![]() These cranks are popular with people, and the market offers a large variety of models and brands. ![]() Therefore, you can find a decent three-piece crank at a budget-friendly price. 3-piece cranks, the three-piece cranks are easily available. Some benefits of 3-piece cranks include: 1. What Are The Advantages of 3-Piece Crank? Notably, they can use a wide range of pedals and bottom brackets. What Is A 3-Piece Crank?Īs the name suggests, a 3-piece crankset has three elements, a spindle, and two separate crank arms. Luckily, the 3-piece crank is easy to replace the spindle. Non- Replaceable Spindleīy any chance, if your 2-piece crank spindle breaks, you will need to buy a new set. So, the 2-piece crank has few designs, sizes, and it is scarce in the market. The 3-piece crank has been in the market for a long time compared to the 2-piece crank, which is new. The formation of the 2-piece crank makes it challenging to eliminate both crank arms since one of them is machine-pressed into the spindle. Alternatively, the other option will be to find a second-hand spare in the market. If your crank cracks or breaks, you must purchase a new crankset. Notably, the 2-piece crank tends to have a higher price rate depending on the brand and model. Which will be stiffer? Drawbacks of a 2-Piece Crank 1. 3-piece crank installed to its perfection. However, this has been a debating issue of 2-piece vs. In reality, the 2-piece cranks are stiffer because the spindle comes as part of the crank arms making the power transfer stronger during pedaling. The attached crank arm adjusts comfortability because it is also used to handle the spindle through the bottom bracket.Īlso, 2-piece cranks are easier to install because the crank arm is welded to the spindle while hydraulically pressed, requiring minor adjustment. Besides, if the added weight were near the front or rear, it would have much impact. It’s also critical to state that heavier cranks aren’t so much of a disadvantage as one may assume due to the position of the weight – at the bikes’ middle. For example, the GANOPPER Square Taper Crankset only weighs 499g (1.1 lbs.) and is compatible with single, double, and triple chainrings. Moreover, less weight results from the pinch bolt on the arm, pre-attached to the spindle. This depends majorly on crank models.īut generally, 2-piece cranks are not heavyweight due to the powerful hollow spindle and larger diameter. It is essential to understand that most 2-piece cranks are more lightweight than 3-piece cranks. What Are The Benefits of 2-Piece Cranks? 1. The 2-piece crankset has a broader bearing positioning with enhanced rigidity and efficiently supplied pedaling force. Moreover, there are precision bearings whose function is to simplify installation and does not require high maintenance. The 2-piece crank has two distinct parts, a free crank arm plus a crank arm with a spindle attached to it.Īlso, the two-piece crankset has an integrated crank arm and a bottom bracket used to increase rigidity with less weight. This is true, especially on mountain bikes, acting just like a stock on beginner budget bikes. With the invention of massive cassettes, 3-piece cranks may somehow be regarded to as an antique form of technology. ![]() However, some bikers still prefer their 2-piece regardless of the additional weight and reasonable reserves. Presently, they rule over the trails.Įven though they are still a favorite for some MTB riders, their gearing choices have totaled the vast ratios succeeded by 11- and 12-speed cassettes from the I cranksets. This way, it brought them into the territory of enduro and cross-country riders. However, innovative work by SRAM to launch the 11- and 12-speed cassettes extended the gear ratios attainable with I piece crank upfront. One-piece cranks are famous to the gravity riders who spent almost all their time downhill and didn’t require a wide gear variety. We have three different types of cranks you can use in an engine:
