I have heard the tsack height is a bit more than most others. However, I really like the size of the platform. Apparently, it is one of the largest out there for clipless road pedals.
Also, the weight is very attractive for the price.
I may just give them a shot for the heck of it, unless there is a known problem with them.
Lectron, everytime you make a post, I always have to click on your pic of the Airborne. Kind of hard not to. If I was to build a Ti bike, it would probably be very similar to your setup.
