Groschopp offers torque hands on right angle gearboxes to supply a pivoted connection supply between your gearbox and a set, stable anchor stage. The torque arm is used to resist torque developed by the gearbox. Basically, it prevents counter rotation of a shaft mounted velocity reducer (SMSR) during procedure of the application.
Unlike various other torque arms which is often troublesome for some angles, the Arc universal torque arm permits you to always position the axle lever at 90 degrees, giving you the most amount of mechanical advantage. The spline design and style enables you to rotate the torque arm lever to almost any point. That is also useful if your fork condition is just a little trickier than normal! Performs great for front and back hub motors. Protect your dropouts - obtain the Arc arm! Made from precision laser lower 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 little bit of support metal added to a bicycle framework to more securely contain the axle of a powerful hubmotor. But let’s backside up and get some good even more perspective on torque hands in general to learn if they are necessary and why they happen to be so important.

Many people want to convert a typical pedal bicycle into a power bicycle to save lots of money over investing in a retail . This is normally an excellent option for a number of reasons and is remarkably easy to do. Many makers have designed simple change kits that can easily bolt onto a typical bicycle to convert it into a power bicycle. The only problem is that the indegent dude that designed your bicycle planned for it to be used with lightweight bike tires, not giant electrical 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 an electric hubmotor. You see, normal bicycle tires don’t apply much torque to the bike dropouts. Front wheels basically don’t apply any torque, therefore the entrance fork of a bicycle is built to simply hold the wheel in place, certainly not resist its torque although it powers the bike with the power of multiple specialist cyclists.

Rear wheels on typical bicycles traditionally do apply a tiny amount of torque about the dropouts, but not more than the standard axle bolts clamped against the dropouts are designed for.
When you swap in an electric hub motor though, that’s when torque turns into an issue. Small motors of 250 watts or less are often fine. Even the front forks are designed for the low torque of these hubmotors. Once you strat to get up to about 500 watts is when concerns can occur, especially if we’re discussing front forks and even more so when the materials is weaker, as in lightweight aluminum forks.
