。前轮的点点还没有磨平。
光滑了不是就没有grip or traction了吗？请问大家怎么看是不是该换外胎啦？ | t********t

发帖数: 91 | 3 From our beloved Sheldon Brown:
Bicycle tires for on-road use have no need of any sort of tread features; in
fact, the best road tires are perfectly smooth, with no tread at all!
Unfortunately, most people assume that a smooth tire will be slippery, so
this type of tire is difficult to sell to unsophisticated cyclists. Most
tire makers cater to this by putting a very fine pattern on their tires,
mainly for cosmetic and marketing reasons.
