I had stability issues with my old XLab torpedo 400 carbon mount... I ordered the Zipp Vuka Alumnia BTA mount but that didnt work either (my aero bars are oval shaped)...

Gave Glen's a try and it worked perfectly.. Funny how the big company's design fails and a small designer makes a great product!

I also combined it with TriSport's BTA modification bracket so that I could orient an XLab torpedo with the cage closer to the stem.



End result:
