Topic kinda directed to the Tarty staff on here, what grinding discs do you use for a medium sharp grind? Or what grinding disc/grind would be most suitable for TNN Lgms? I recently got a back wheel off my mate - swapped, and it had a tarty grind he previously got a few months ago. It was in need for a fresh grind sooner than later but it still worked ace with TNNs. I gave my rim a fresh grind with a stone cutting disc, attempting to give it a medium sharp grind. It's good but thought it would be a bit better. The bite is ace, it sounds kinda like Stan Shaw's brake where he's riding that quarry in the rain. A loud high pitched sharp squeak. It's just lacking the hold. Or I might just being paranoid about the whole situation aha. help.
