I've been a fan of Fix-It Sticks since their first successful Kickstarter a couple of years ago. The little orange tools are simple, versatile, and extremely portable. I find myself using them on a near daily basis for small operations here and there.
The original toolkit came in a small pouch made from a repurposed inner tube. This would presumably be packed in a saddle bag or other storage. Fix It Sticks has recently unveiled another storage option: a nylon bracket that mounts beneath a water bottle cage, leaving the tools easily accessible and allowing you to snap the tools in and out whenever needed.
From a convenience perspective, it's a great little part. From an aero perspective, it may be difficult to find a good spot for this bracket on your tri bike. It's likely to stick out into the wind in most places you'd find a set of bottle bosses. It's probably best suited for use on rear-mounted bottle carriers, where it would sit in the aero wake of the rider (this is why rear-mounted bottles are a good aerodynamic choice in the first place).
