Groschopp offers torque hands on right position gearboxes to provide a pivoted connection resource between your gearbox and a set, stable anchor level. The torque arm is used to resist torque developed by the gearbox. Put simply, it prevents counter rotation of a shaft attached rate reducer (SMSR) during procedure of the application.
Unlike different torque arms that can be troublesome for a few angles, the Arc universal torque arm allows you to always position the axle lever at 90 degrees, providing you the the majority of amount of mechanical advantage. The spline style lets you rotate the torque arm lever to almost any point. This is also useful if your fork circumstances is a little trickier than normal! Works great for front and back hub motors. Protect your dropouts – acquire the Arc arm! Made from precision laser trim 6mm stainless steel 316 for excellent mechanical hardness. Includes washers to carry the spline section, hose clamps and fasteners.
A torque arm is an extra piece of support metal put into a bicycle framework to more securely contain the axle of a robust hubmotor. But let’s rear up and get some even more perspective on torque arms in general to learn if they are necessary and just why they are so important.

Many people choose to convert a typical pedal bicycle into a power bicycle to save money over purchasing a retail . This is certainly an excellent option for numerous reasons and is amazingly simple to do. Many suppliers have designed simple transformation kits that can easily bolt onto a typical bike to convert it into an electric bicycle. The only problem is that the indegent guy that designed your bike planned for this to be utilized with lightweight bike tires, not giant electrical hub motors. But don’t worry, that’s where torque arms can be found in!
Torque arms is there to greatly help your bicycle’s dropouts (the area of the bike that holds onto the axles of the wheels) resist the torque of a power hubmotor. You see, typical bicycle tires don’t apply much torque to the bicycle dropouts. Front wheels essentially don’t apply any torque, therefore the front side fork of a bicycle is made to simply hold the wheel in place, not resist its torque while it powers the bike with the force of multiple specialist cyclists.

Rear wheels on standard bicycles traditionally do apply a small amount of torque in the dropouts, but not more than the typical axle bolts clamped against the dropouts are designed for.
When you swap in an electric hub engine though, that’s when torque turns into a concern. Small motors of 250 watts or much less are usually fine. Even front forks are designed for the low torque of these hubmotors. Once you strat to get up to about 500 watts is when challenges can occur, especially if we’re talking about front forks and much more so when the material is weaker, as in metal forks.
