I had some hack bikeshop work on my Radrover and had re do the work done on my brakes, Anyway, The guy was so heavy handed he overtightened the brake cable on the caliper adjustment and frayed the cable, (along with other shoddy work)
Do I have to buy this cable from Rad: https://bit.ly/3BuVhQc
Or can I just go to amazon (https://amzn.to/3zNVPjb),
Thanks, Paul
