Fortunately, it wasn’t off by much, but it tweaked the alignment ever so slightly and caused the cage to twist. In the end, once the cage was bolted in place, I realized that one of the bosses was misaligned along its cylindrical axis. Even after I created a small pilot hole for each boss, the bigger drill bit shifted to the side a little. In short, I found that a standard power drill was difficult to align on the cylindrical steel tube the bit tended to drift around the tube. To be clear, I thought of creating a drill guide after the fact. And if you’re adding mounts to the downtube, hold a cage and bottle in place to check for adequate tire clearance. 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.

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.
