I think this cable is phenomenal. It�s very durable. Doesn�t really stretch. A lot gives smooth accurate shifting all the time. Very happy with this product.
New cables are always nice but these seem smoother than stock Shimano cables and they definitely last longer. I had about 3000 miles on the rear derailleur cable and thought it was getting frayed since my downshifting was sluggish but it turns out the new cassette I installed was apparently a different width - I went from 11-30 to 11-32. The cable still looked like it was in good shape, not sure how much longer it would have lasted but the Shimano cables typically last about 3K it seems so I'm impressed with these, I feel like paying the few extra dollars is worth it.
