Groschopp offers torque hands on right position gearboxes to provide a pivoted connection resource between your gearbox and a fixed, stable anchor stage. The torque arm is used to resist torque produced by the gearbox. In other words, it prevents counter rotation of a shaft mounted speed reducer (SMSR) during procedure of the application.
Unlike different torque arms which can be troublesome for some angles, the Arc universal torque arm allows you to always position the axle lever at 90 degrees, giving you the the majority of amount of mechanical advantage. The spline style lets you rotate the torque arm lever to nearly every point. This is also handy if your fork condition is just a little trickier than normal! Performs great for front and backside hub motors. Protect your dropouts – obtain the Arc arm! Created from precision laser slice 6mm stainless steel 316 for remarkable mechanical hardness. Includes washers to carry 
the spline section, hose clamps and fasteners.
A torque arm can be an extra piece of support metal added to a bicycle frame to more securely hold the axle of a powerful hubmotor. But let’s back up and get some good more perspective on torque hands in general to learn if they are necessary and why they are so important.
Many people tend to convert a typical pedal bicycle into a power bicycle to save lots of money over purchasing a retail . This is a great option for a number of reasons and is remarkably simple to do. Many suppliers have designed simple transformation kits that can easily bolt onto a standard bicycle to convert it into an electric bicycle. The only problem is that the poor man that designed your bike planned for it to be utilized with lightweight bike tires, not giant electric hub motors. But don’t get worried, that’s where torque arms can be found in!
Torque arms are there to greatly help your bicycle’s dropouts (the part of the bike that holds onto the axles of the wheels) resist the torque of a power hubmotor. You see, common bicycle wheels don’t apply very much torque to the bicycle dropouts. Front wheels actually don’t apply any torque, so the front fork of a bike is designed to simply hold the wheel in place, not really resist its torque while it powers the bike with the drive of multiple professional cyclists.
Rear wheels on common bicycles traditionally do apply a small amount of torque on the dropouts, but not more than the standard axle bolts clamped against the dropouts can handle.
When you swap within an electric hub motor though, that’s when torque becomes an issue. Small motors of 250 watts or fewer are often fine. Even the front forks can handle the low torque of the hubmotors. Once you strat to get up to about 500 watts is when complications can occur, especially if we’re talking about front forks and much more so when the materials is certainly weaker, as in lightweight aluminum forks.
