Salsa Lip-Lock Seatpost Collar

This is just one of those things that you lump in to the cost of buying a new bike, along with a Thomson post and and whatever saddle you prefer to ride. Even top end bikes usually come with some glorified pipe clamp with a junk bolt threaded directly into low quality aluminum. Strippedloose seat binder tops the list of unlikely equipment failures that I hear from DNF'd racers all the time. Get your saddle where you want it and then KEEP IT THERE. The steel nut-insert in this makes it about infinity percent better than most stock binders and the bolt is a nice big hex size that you will never strip. It's like one gram heavier... do it.

Tightened it down to 4NM and have not had a problem. The seats stays in place and doesn't move. Great product

Perfect fit. No more slip. Well machined part.
