Hi all,   I've experienced for 3 month a 108.9... and after many crackings, it just break out under my feet, leaving me bloody tibiae..  Thus I am aware of your experience, with other freewheel... before buying one.  I know the ENO trial which is the reference for many riders in France... and feedbacks looks good...  I know the Tensile (less expensive)-avaible on tartybikes-  but I didn't hear anything about it...  There is the Monty too... but it seems to be the same manufacturer than the koxx one (108.9).   Thank you for helping me
