Personally, I've taken an allen key and cut it down so that it will reach just long enough to tighten my 17t 32p pinion right down. it's a little awkward the first few times, but imho, unless you run on different tracks that require different gearing, you won't change pinions often, and I didn't want to drill a hole in my gear covers...
