U*****e 发帖数: 2882 | 1 正考虑上cyclocross bike, 在网上看到这一段说碟闸好。
High quality cyclocross bicycles come with disc brakes . Disc brakes are
effective in muddy conditions because they prevent clogging and use
hydraulic systems instead of cable operated brakes to simplify the bike
frame.
然后下面介绍cyclocross races,说比赛规则禁止使用碟闸。
In order to compete in cyclocross races, there are specific adjustments that
all bikes must adhere to.
* Handlebars must not be more than 50 cm.
* Tires must not be thicker than 35 mm.
* Wheels must have at least 12 spokes.
* Bikes must not weigh less than 15 lbs.
* Disc brakes are forbidden.

这算怎么回事呢? |

, if the race organizers say you cannot, then just get one with regular
brakes. (did you ask them why disc brakes are forbidden?) |

cyclocross bikes have disc brakes. |

t****u 发帖数: 10218 | 6 The disc brake ban was an old stupid UCI rule that has already been lifted.
From this year disc is allowed, and tire width is reduced to 33mm.
Of course if the race is not UCI sanctioned, all things are possible. |
