Groschopp offers torque arms on right position gearboxes to supply a pivoted connection source between your gearbox and a set, stable anchor level. The torque arm is used to resist torque developed by the gearbox. Quite simply, it prevents counter rotation of a shaft mounted rate reducer (SMSR) during operation of the application.
Unlike additional torque arms which is often troublesome for a few angles, the Arc universal torque arm permits you to always position the axle lever at 90 degrees, giving you the the majority of amount of mechanical advantage. The spline style allows you to rotate the torque arm lever to nearly every point. This is also convenient if your fork scenario is a little trickier than normal! Functions ideal for front and back hub motors. Protect your dropouts – get the Arc arm! Made from precision laser cut 6mm stainless steel 316 for superb mechanical hardness. Includes washers to carry the spline section, hose clamps and fasteners.
A torque arm can be an extra little bit of support metal put into a bicycle frame to more securely contain the axle of a powerful hubmotor. But let’s back up and get some more perspective on torque arms in general to learn if they are necessary and why they are so important.

Many people choose to convert a typical pedal bicycle into a power bicycle to save lots of money over purchasing a retail . This is normally a great option for numerous reasons and is amazingly easy to do. Many producers have designed Torque Arm china simple transformation kits that may easily bolt onto a standard bike to convert it into a power bicycle. The only problem is that the poor person 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 can be found in!
Torque arms are 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, usual bicycle wheels don’t apply much torque to the bike dropouts. Front wheels truly don’t apply any torque, therefore the front fork of a bicycle is made to simply hold the wheel in place, not really 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 upon the dropouts, but not more than the standard axle bolts clamped against the dropouts are designed for.
When you swap in an electric hub engine though, that’s when torque becomes an issue. Small motors of 250 watts or much less are usually fine. Even entrance forks are designed for the low torque of the hubmotors. Once you strat to get up to about 500 watts is when concerns may appear, especially if we’re talking about front forks and much more so when the material is definitely weaker, as in light weight aluminum forks.
