Groschopp offers torque hands on right angle gearboxes to provide a pivoted connection resource between the gearbox and a fixed, stable anchor point. The torque arm is employed to resist torque developed by the gearbox. Basically, it prevents counter rotation of a shaft installed velocity reducer (SMSR) during operation of the application.
Unlike various other 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, providing you the most amount of mechanical advantage. The spline style permits you to rotate the torque arm lever to nearly every point. This is also convenient if your fork circumstances is a little trickier than normal! Performs great for front and backside hub motors. Protect your dropouts – get the Arc arm! Created from precision laser slice 6mm stainless steel 316 for superb mechanical hardness. Includes washers to carry the spline section, hose clamps and fasteners.
A torque arm is an extra little bit of support metal added to a bicycle body to more securely contain the axle of a robust hubmotor. But let’s returning up and get some even more perspective on torque hands generally speaking to learn if they are necessary and why they are so important.

Many people decide to convert a typical pedal bicycle into a power bicycle to save lots of money over purchasing a retail . This is an excellent option for several reasons and is surprisingly simple to do. Many makers have designed simple change kits that can certainly bolt onto a standard bicycle to convert it into an electric bicycle. The only issue is that the indegent guy that designed your bicycle planned for it to be utilized with lightweight bike wheels, not giant electric hub motors. But don’t get worried, that’s where torque arms come in!
Torque arms are there to help your bicycle’s dropouts (the area of the bike that holds onto the axles of the wheels) resist the torque of an electric hubmotor. You see, common bicycle tires don’t apply much torque to the bicycle dropouts. Front wheels basically don’t apply any torque, so the front side fork of a bike was created to simply hold the wheel in place, not really resist its torque while it powers the bike with the force of multiple specialist cyclists.

Rear wheels on regular bicycles traditionally do apply a tiny amount of torque in the dropouts, however, not more than the typical axle bolts clamped against the dropouts can handle.
When you swap in an electric hub engine though, that’s when torque becomes a concern. Small motors of 250 watts or less are generally 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 concerns can occur, especially if we’re talking about front forks and even more so when the material is definitely weaker, as in light weight aluminum forks.
