Groschopp offers torque arms on right position gearboxes to provide a pivoted connection resource between your gearbox and a set, stable anchor stage. The torque arm is utilized to resist torque produced by the gearbox. Put simply, it prevents counter rotation of a shaft mounted acceleration reducer (SMSR) during operation of the application.
Unlike 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 design enables you to rotate the torque arm lever to almost any point. This is also helpful if your fork scenario is just a little trickier than normal! Performs great for front and rear hub motors. Protect your dropouts – get the Arc arm! Created from precision laser trim 6mm stainless 316 for remarkable mechanical hardness. Includes washers to carry the spline section, hose clamps and fasteners.

torque arm can be an extra piece 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 good even more perspective on torque hands in general to learn when they are necessary and why they are so important.
Many people decide to convert a standard pedal bicycle into a power bicycle to save money over investing in a retail . This is normally an excellent option for numerous reasons and is amazingly simple to do. Many producers have designed simple alteration kits that may easily bolt onto a typical bike to convert it into an electric bicycle. The only issue is that the indegent dude that designed your bicycle planned for this to be used with lightweight bike tires, not giant electric hub motors. But don’t be anxious, that’s where torque arms can be found 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, usual bicycle wheels don’t apply very much torque to the bike dropouts. Front wheels actually don’t apply any torque, so the front fork of a bike is built to simply hold the wheel in place, not resist its torque while it powers the bike with the drive of multiple professional cyclists.
Rear wheels on common bicycles traditionally do apply a tiny amount of torque about the dropouts, however, not more than the standard axle bolts clamped against the dropouts can handle.
When you swap within an electric hub electric motor though, that’s when torque becomes a concern. Small motors of 250 watts or a smaller amount are usually 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 challenges may appear, especially if we’re talking about front forks and even more so when the material is weaker, as in aluminium forks.
