I've recently got the Trialtech 108 click and I love it ! It has good engagement , it is a fair price , it is pretty loud too. Also the bearings are pretty smooth, and when I ride it I notice this as my freewheel spins for longer than my old freewheel,which is quite a good advantage for me as I have to ride quite far from my house to get to the good places to ride in my area. Hope this helps,
Ellis.
