Nope, seat tube mounted chain catcher with an extension. Should have it any day. The BB is press fit so nothing to mount to.
I have a 11-23 on there now. Even with a 34, I can do 30 mph @ 120 rpm (my comfortable max). It is very rare on courses out here (Illinois) that we can go that fast for any length of time. At 100 rpm, I'm still doing 25 mph and this is typical in fast sections.
I plan to try it and if I end up spinning it out very often, I'll change to a 39 and have the quarq re-calibrated.
