Just bought a 2009 Niner Sir 9 with these brakes on them. They need at the very least a good bleed and rear pads. Is it worth putting any work into these or should I just replace? Thanks!
They look ok condition wise. I’d bleed them and see how it goes.
I run a pair and they’re fine . Easy to bleed

They’re good brakes. If they just need a flush, I would run them.

I agree they are good brakes. Store your bike indoors if you reside in a cold climate. The Shimano brake piston O rings are terrible. In the winter mineral oil will leak around the seal and contaminate your pads and rotors. Change the rear pads for new ones. Do a complete bleed of both brakes clean everything with iso and enjoy these brakes. They have good stoping power. Increase rotor size with the adapters if you feel them fading. ST 🙂
