You oughta replace your straddle wire whenever you replace your other cables. Don’t let em get all stiff and rusty and kinked. That makes your brake sad and resentful, and they will let you down like that kid in elementary school who said he was investing your lunch money in the futures market but he was really just using it to buy more strawberry scented markers. Remember when you were encouraged to sniff markers? I do! This Centerpull Brake Straddle Wire fits most Diacompe and Old Weinmann Centerpull Brakes. Not for use on Paul Racer brakes. Use a Cantilever Brake Straddle wire for those. Got old Mafac Centerpulls or Cantis? Use a Shift cable as the straddle wire.
