Amanda, I'm not familiar with that particular light, but most have some adjustability in the mounting bracket. For some, it's obvious- new o-ring thingy or whatever. For others, not so much- my Tri-Newt actually requires some minor disassembly and reassembly to make it fit larger bars. Any chance that it can be adjusted or that the company sells a bigger bracket? I hope that you can get it to work!

Oh, and big thumbs-up for the MiNewt too Those Li-ion batteries have awesome run times
