After designing a few different torque arms for various bike frames, I have a pretty good grasp on technique and attachment method.
Generally, I like to use 1/4" thick 316 Stainless Steel, as it seems to be strong enough for most applications, and is readily available from my various sources.
To date, I have designed Custom Torque arms for the following Bike Frames, and all are available for sale:
- Genesis V2100 https://www.walmart.com/ip/26-Men-s-Gen ... e/47443504
- Mongoose Dolomite https://www.walmart.com/ip/26-Mongoose- ... d/29741123
- Mongoose Hitch https://www.walmart.com/ip/26-Mongoose- ... d/42248079

For bikes not listed above, I will do my best to design and fabricate a set of custom torque arms for your frame. What I will need is a couple good photos, which I can import into my CAD software, and scale accurately. The best way to do this is to take a high resolution photo, straight on shot of each side of your bike's drop-outs, with a metric scale/ruler near the drop-out slots. (See Example Photos below). The metric ruler helps me to size the photo accurately in CAD. I then will engineer a profile for you to review. It will first be mailed to you as a PDF file for you to print, and model up within your frame. If all looks good, I will add your torque arms to my next batch of parts. This process will generally take 4-6 weeks. Cost for new designs will run about $300 for the first set, and $125 for additional sets of the same design, including shipping.
