Groschopp offers torque hands on right angle gearboxes to provide a pivoted connection origin between your gearbox and a fixed, stable anchor level. The torque arm can be used to resist torque produced by the gearbox. In other words, it prevents counter rotation of a shaft attached swiftness reducer (SMSR) during procedure 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, giving you the the majority of amount of mechanical advantage. The spline design and style enables you to rotate the torque arm lever to nearly every point. This is also helpful if your fork problem is just a little trickier than normal! Performs ideal for front and back hub motors. Protect your dropouts – get the Arc arm! Made from precision laser slice 6mm stainless steel 316 for good 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 framework to more securely contain the axle of a robust hubmotor. But let’s back up and get some more perspective on torque arms generally speaking to learn if they are necessary and just why they are so important.

Many people decide to convert a typical pedal bicycle into a power bicycle to save money over investing in a retail . This can be an excellent option for several reasons and is amazingly simple to do. Many producers have designed simple transformation kits that can simply bolt onto a standard bicycle to convert it into an electric bicycle. The only trouble is that the indegent person that designed your bike planned for it to be used with lightweight bike wheels, not giant electrical hub motors. But don’t be anxious, 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, ordinary bicycle wheels don’t apply very much torque to the bicycle dropouts. Front wheels in fact don’t apply any torque, therefore the the front fork of a bicycle is built to simply hold the wheel in place, certainly not resist its torque while it powers the bike with the power of multiple specialist cyclists.

Rear wheels on typical bicycles traditionally do apply a little amount of torque in the dropouts, however, 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 an issue. Small motors of 250 watts or less 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 challenges may appear, especially if we’re discussing front forks and even more so when the material can be weaker, as in lightweight aluminum forks.
