Groschopp offers torque arms on right position gearboxes to provide a pivoted connection resource between the gearbox and a set, stable anchor stage. The torque arm is used to resist torque developed by the gearbox. Put simply, it prevents counter rotation of a shaft installed rate reducer (SMSR) during operation of the application.
Unlike different torque arms which may be troublesome for a few angles, the Arc universal torque arm enables you to always position the axle lever at 90 degrees, giving you the many amount of mechanical advantage. The spline design allows you to rotate the torque arm lever to almost any point. That is also useful if your fork scenario is a little trickier than normal! Functions great for front and backside hub motors. Protect your dropouts – obtain the Arc arm! Created from precision laser trim 6mm stainless 316 for excellent mechanical hardness. Includes washers to hold the spline section, hose clamps and fasteners.
A torque arm is an extra little bit of support metal put into a bicycle frame to more securely hold the axle of a powerful hubmotor. But let’s rear up and get some more perspective on torque hands in general to learn when they are necessary and just why they will be so important.
Many people decide to convert a typical pedal bicycle into a power bicycle to save money over investing in a Torque Arm china retail . This is definitely a great option for numerous reasons and is surprisingly easy to do. Many manufacturers have designed simple transformation kits that can simply bolt onto a typical bicycle to convert it into an electric bicycle. The only trouble is that the poor man that designed your bicycle planned for this 
to be used with lightweight bike tires, not giant electrical hub motors. But don’t get worried, that’s where torque arms come in!
Torque arms is there to 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, ordinary bicycle wheels don’t apply much torque to the bicycle dropouts. Front wheels actually don’t apply any torque, therefore the the front fork of a bicycle is built to simply hold the wheel in place, not really resist its torque while it powers the bike with the push of multiple specialist cyclists.
Rear wheels on normal bicycles traditionally do apply a little amount of torque about the dropouts, but not more than the typical axle bolts clamped against the dropouts can handle.
When you swap within an electric hub electric motor though, that’s when torque turns into a concern. Small motors of 250 watts or a smaller amount are often fine. Even the front forks can handle the low torque of these hubmotors. Once you start getting up to about 500 watts is when complications may appear, especially if we’re discussing front forks and even more so when the material is usually weaker, as in lightweight aluminum forks.
