Take foot clearance into account if you are angling it rearward. If you are adding rivnut bosses to a fork, make sure to carefully consider what angle you want the cage to be oriented, as well as how it will interact with other components and luggage, such as a rack.
Simply hold the cage against the fork or downtube and mark the three holes with a Sharpie.

As long as you have a drill, the biggest investment is the actual rivet nut tool. However, there are also zinc-plated carbon steel options that might work even better with a chromoly frame.įortunately, there aren’t too many things you need to make this happen, aside from a standard power drill and a few odds and ends. After a bit of research, I chose to use stainless steel rivet nuts as they won’t corrode when in contact with Chromoly steel like aluminum inserts would. Rivnuts come in several types of metal as well. To match the threading of a standard bottle boss, you need the M5 x 0.80 size rivnuts. “Rivnuts,” also known as rivet nuts or threaded rivet inserts, come in all shapes and sizes.

Alternatively, look into have a frame builder braze on threaded water bottle bosses, or there are many other ways to mount bags and cages-stay tuned for a full list. In the end, it’s much cheaper than buying a new fork. Unless I was expecting to haul an extremely heavy load, or to encounter massive drops and jumps, I personally wouldn’t hesitate to do this with any production steel MTB frame. That said, steel MTB forks/frames are built to carry a lot of weight, and to withstand very rugged circumstances. So, if you are interested in drilling holes in a perfectly good steel frame, here’s how it went and what we used to make it happen.īefore we go on, are you sure you want to drill holes in your frame? Be aware that rivnuts require rather larges holes (~7mm) and some folks suggest that they might weaken the frame. it’s more about how I did it and what I’d do differently if I were to do it again. Now that we have another related post in the works, I thought I’d finally dig up my notes and photos to share what I learned. The rivnut on the middle-right is partially compressed next to others left uncompressed.
