We set out to solve the issue of Axle Spin Out, and can say that our V5, V6, and V7 Arms are the best torque arms ever designed for hub motors with axle flats. V5 Torque Arm - Eyelets Our V5 installs front or rear on any frame with fender eyelets. The versatile press-fit insert is made of specially hardened 17-4 steel . Need to fix a flat? All of our torque arms simply detach by loosening one bolt. The V6 installs front or rear adapting to frames that lack fender eyelets. The Arm is fastened to your frame via the Frame Clamp and two hose clamps. Just like the V5, the V6 uses press-fit Axle Insert made of specially hardened 17-4 steel . The V7 installs front or rear and exerts up to 2000lbs of clamping force to secure the axle in place. The Arm is fastened to your frame via the Frame Clamp and two hose clamps. The V7 uses two grade 12.9 bolts and specially hardened 17-4 steel for the clamp making it the ultimate Torque Arm for regen capable motors. Review: Very heavy duty, bolt sketches me out, and hose clamps sturdy but I hate em - Well grin tech makes a lot of quality stuff. This thing is pretty up to snuff. It came pretty snug to my axle, though I am not sure of the exact science behind torque arms because it's not exactly a perfect fit up and down, it's a "universal" Installation was difficult with the hose clamps. I decided to cut them shorter which was a big mistake. I was sweating like crazy, grunting because of this little fateful decision, don't do what I did. The shrink wrap didn't stay, I wouldn't put it on there I am little sketched out by the bolt and lock nut that holds it all together I used an 11mm socket and 7/16 wrench which comes out to roughly 11.10 mm. It's all that I had but it worked. I am not sure how this bolt is going to not slide. I want to get a tac from a welder on that bolt. Other than that it seems really high quality steel. I just have to pray to God my flat prevention plan (FPP) is going to be solid because I just got 7 flats in a row on the motor wheel and I can't get another one without going balastic. So just so ya know if you have more than one of these it's a pain in the ass to get the wheel off! Try patching a flat with the motor on! 😂 Just crossing my fingers hoping this thing keeps my wheel in Review: Torque arms that really work, and fit the axle. - If you are building an E-bike these are the torque arms you want. They are nice and thick, are well made and fit snugly on the hubmotor axle. I've tried others and most were loose on the axle. These torque arms work well, just order the correct ones, front or rear and enjoy your E-bike without having to worry about the axle twisting out. Tip, make sure you preload it against the rotation of the axle and use thread locker. Yes I do reccomend these torque arms! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00K57N9II | | Auto Part Orientation | Front | | Auto Part Position | Front | | Automotive Fit Type | Universal Fit | | Best Sellers Rank | #565,121 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #1,558 in Adult Electric Bicycles | | Brand | Grin Technologies | | Brand Name | Grin Technologies | | Color | Stainless Steel | | Customer Reviews | 4.4 out of 5 stars 78 Reviews | | Fit Type | Universal Fit | | Manufacturer | Grin Technologies Ltd | | Manufacturer Part Number | COMINSO5JUL42056 | | Material | Stainless | | Material Type | Stainless | | Orientation | Front | | UPC | 628461000232 | ## Product Details - **Brand:** Grin Technologies - **Fit Type:** Universal Fit - **Auto Part Position:** Front - **Material:** Stainless - **Orientation:** Front ## Images ![Universal Ebike Torque Arm For Front Hub Motors.

My tire fell off in traffic** A: It's possible to fit on both the left and right sides if your motor has cable exiting the side of the axle. But if the wire exits the end of the axle, then to fit one on the wire side you'll need to cut off and reattach the electrical connectors as they won't usually fit through the cutout of the torque arm plate. **Q: Would this work on a rear hub motor? Or is there on specific for rear** A: This is not recommended for a rear installation. The geometry of the plates was put together with a front fork in mind. Have a look at this option for rear motors: https://www.amazon.com/Grin-Technologies-Universal-Electric-ebikes/dp/B00K60C67Y?ref_=bl_dp_s_web_9287828011 **Q: Is this a pair for both sides or just one?** A: It is a pair. It has several adjustments to make seeing on side and behind easy. **Q: I have a 1500 w front hum motor. Will it work for this set up?** A: If you have a hub motor with M14 axle diameter that is machined to 10mm on the flats, then it will work with power levels up to 1500 watts pretty well. But I wouldn't be comfortable putting that much power through an M12 axle which doesn't have nearly as much bite against spinout. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very heavy duty, bolt sketches me out, and hose clamps sturdy but I hate em *by M***N on April 17, 2022* Well grin tech makes a lot of quality stuff.

I think it is too expensive for the little bit of stainless steel you get but it actually does what it is supposed to. I'm sure the sting of the price will fade in time but this thing looks like it will last forever. ## Frequently Bought Together - Grin Technologies Universal Ebike Torque Arm For Front Hub Motors.
