Dimension Seat Binder Bolt Assembly (Steel/Alloy) (Black)
Not an item to get excited about, but it helped me a lot! The skewer on my project bike frame - with brazed fittings - could not hold the seat post without sinking. Replacing it with this handsome hardware not only solved the problem, but it made my frame look nicer. There is an elegant cut on the seat tube that can now be seen. Binder bolts were a typical recommendation back in the bad old days when quick release seat posts first became popular and seats were regularly getting stolen. Very happy.
