Mash / Cinelli Vigorelli

I feel I need to overtighten the hub bolts in order to keep the correct chain tension. In that sense I am affraid of damaging the dropouts that's why I thought about installing the MKS tug chain tensioner. Can you guys give your poit of view if u would install this device in a Mash?

Tusen takk :)

Replaced it with the Phil Wood Dome, the allen bolt have little surface area to sufficently grip the track end.
