1. If you wanna go fast, you need these
Braided lines on an old bike will dramatically improve how the brakes feel. Toss in a rebuild kit for your calipers and master. Get some DOT 5.1 fluid. You'll end up needing just one finger to slow down after seeing the highway patrol hiding under the overpass.
Spiegler lines are a great brand. Sure, you can get them from other retailers, but then how are you gonna rack up that sweet, sweet STG cash? STG also had more color combos available than the others I found, with no extra charge. Lead time was maybe a day before shipment.
Get those old rubber lines outta there. Replace them with these. They'll brake better and look better.
