Mavic SLR轮组有自己的调整机制，官方话就是QRM。轮组附件里就有调整工具，但是为何要调整，要如何调整，包括我和许多用SLR轮组的车友可能都不是很清楚，现在结合TW网友的网文在这里说说，要不然等轮组烂掉可能都还不清楚这个调整时怎么回事。

　　先看看原厂的说明

　　1.1 free play adjustment

　　Hub play must always be gauged with the wheel fitted and tightened in the frame or fork. Tightening the quick release skewer significantly increases the lateral pressure

　　exerted on the bearings. Therefore:

　　? if there is play in a wheel not fitted into the frame or fork, it may disappear once the wheel has been fitted;

　　? if there is no play in a wheel not fitted into the frame or fork, it is possible that tightening the quick release skewer will over-stress the bearings, thus damaging them.

　　Adjust the adjustment nut by fully tightening it and then untightening it by a 1/4 turn, so as to close the quick release lever （CLOSE position） with a suitably large force.

　　However, a too large tightening force may damage the bearings.

　　This tightening force is a subjective parameter that is directly dependent on the end user, and as such it is difficult to accurately determine the optimum bearing adjustment

　　at the factory.

　　In order to avoid any problems for your customers, we factory set bearing play by simulating an extreme quick release tightening force.

　　There is therefore likely to be some play in the hub of a new wheel fitted to a bike with a lower quick release tightening force than that used in the factory.

　　Apply the following procedures to set the amount of play.

　　WARNING: Adjusting the play is a delicate operation which consists of identifying the balance point between play and no play.

　　Having no play does not necessarily mean that the hub is correctly adjusted as the bearings may be over-stressed.

　　1.1.1. QRM+ HUB

　　QRM+ designates Mavic hubs that can be adjusted using the hub wrench M40123. For the 2005 range, this concept is used on the following wheels:

　　? iO

　　? Comete road and track

　　? Cosmic Carbone SL

　　? Ksyrium SL

　　? Ksyrium Elite

　　? Crossmax SL and SL Disc

　　? Crossmax XL and XL Disc

　　? Deemax UST

　　This hub has an adjustment nut on the left hand side of the wheel compatible with the hub wrench M40123.

　　This very simple system allows very accurate and quick adjustment of bearing play.

　　PROCEDURE

　　Tools needed

　　? 1 hub wrench M40123

　　1. Fit the wheel in the frame or fork and tighten the quick release skewer using a reasonable force;

　　2. Delicately move the top of the wheel to the right and then the left of the bike to feel the play;

　　? If there is some play, lightly tighten the adjustment nut using the hub wrench M40123 and check for play: repeat the operation as many times as required until there

　　is no play;

　　? If there is no play, to be sure the bearings are not over-stressed, untighten the adjustment nut until some play can be felt and then carry out the above operation.

　　The 4 lugs of the hub wrench M40123 must be fully inserted into the holes of the adjustment nut, making sure to correctly position the wrench against the nut

　　（on Crossmax XL Disc and Deemax UST front wheels, only the 2 lugs at the extremities of the wrench are used）。

　　To avoid damaging the bearings due to over tightening of the adjustment nut, the wrench M40123 is made from resin: a sort of safety valve; the lugs will break before the

　　bearings are damaged.

　　在轮组上花鼓是用于轮组与车架（前叉）之间的一个滑动零件，而轮组与车架（前叉）之间连结的时候，就是靠快拆。只要将快拆锁上适合的力量以后，轮组就可以和车架（前叉）通过快拆锁紧，我们就可以快快乐乐的骑车了。

　　但在轮组花鼓与车架（前叉）透过快拆锁紧以才能工作，这时候花鼓尺寸与车架 （前叉）尺寸势必会有一定的公差存在。如果将快拆锁紧以后，造成花鼓的轴承所受到的压力过大，如此一来轮组就会转动不顺。假使快拆上紧 了以后，因为花鼓与车架之间的距离没有配合适当，如此一来就会造成轮组会左右晃动，造成行车危险，虽然这个晃动可能很小。

　　简单的说：

　　快拆上紧->花鼓与车架（前叉）间距过小->花鼓中的轴承所受压力过大 = 轮组转动不顺

　　快拆上紧->花鼓与车架（前叉）间距过大->花鼓中的轴承所受压力过小 = 轮组会左右晃动

　　因此Mavic 在一些轮组中可以微调花鼓来解决以上的问题。当然SLR也是有提供这种功能的调整，这个调整的机制被称为QRM。

　　其实轮组在出厂的时候都有基本的预设值，基本上不至于买轮组以后，不调整会造成危险或培林的损毁。

　　买轮组的时候就会附有专门的调整工具。这种工具有防止培林被所太紧而坏调的机制。

　　MAVIC QRM调整工具

　　动手调整

　　调整时，首先要将轮组装到车架（前叉）上面，再将快拆锁上合适的力量，不要过紧或过松。

　　可以看到花鼓的右边有几个小洞。

　　再用工具的凸出点去调整即可。

　　前轮是与前叉配合。调整到适合得松紧度。

　　后轮则是与车架配合，后轮的照片比较可以看清楚花鼓上的凹点。

　　如何才知道是否有锁到合适的力量呢？

　　假使所的过紧，可以很明显发现轮组越来越难转动。越来越不顺。

　　假使所的太松，轮组转起来会变得很顺，但是也会左右摇摆。

　　所以调整的时，所谓合适的松紧度，用手去晃轮组的时候，轮组是不会向左右晃动的就可以了。

　　要用手去推推看，轮组是否会向左右两边晃动，如果会就是太松了。假使调的过紧的话，转动会很涩，过于紧会让轴承增加磨损，从而减少轴承的使用寿命。
