　　Mavic SLR輪組有自己的調(diào)整機(jī)制，官方話就是QRM。輪組附件里就有調(diào)整工具，但是為何要調(diào)整，要如何調(diào)整，包括我和許多用SLR輪組的車友可能都不是很清楚，現(xiàn)在結(jié)合TW網(wǎng)友的網(wǎng)文在這里說說，要不然等輪組爛掉可能都還不清楚這個(gè)調(diào)整時(shí)怎么回事。

　　先看看原廠的說明

　　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.

　　在輪組上花鼓是用于輪組與車架（前叉）之間的一個(gè)滑動(dòng)零件，而輪組與車架（前叉）之間連結(jié)的時(shí)候，就是靠快拆。只要將快拆鎖上適合的力量以后，輪組就可以和車架（前叉）通過快拆鎖緊，我們就可以快快樂樂的騎車了。

　　但在輪組花鼓與車架（前叉）透過快拆鎖緊以才能工作，這時(shí)候花鼓尺寸與車架 （前叉）尺寸勢(shì)必會(huì)有一定的公差存在。如果將快拆鎖緊以后，造成花鼓的軸承所受到的壓力過大，如此一來輪組就會(huì)轉(zhuǎn)動(dòng)不順。假使快拆上緊 了以后，因?yàn)榛ü呐c車架之間的距離沒有配合適當(dāng)，如此一來就會(huì)造成輪組會(huì)左右晃動(dòng)，造成行車危險(xiǎn)，雖然這個(gè)晃動(dòng)可能很小。

　　簡(jiǎn)單的說：

　　快拆上緊->花鼓與車架（前叉）間距過小->花鼓中的軸承所受壓力過大 = 輪組轉(zhuǎn)動(dòng)不順

　　快拆上緊->花鼓與車架（前叉）間距過大->花鼓中的軸承所受壓力過小 = 輪組會(huì)左右晃動(dòng)

　　因此Mavic 在一些輪組中可以微調(diào)花鼓來解決以上的問題。當(dāng)然SLR也是有提供這種功能的調(diào)整，這個(gè)調(diào)整的機(jī)制被稱為QRM。

　　其實(shí)輪組在出廠的時(shí)候都有基本的預(yù)設(shè)值，基本上不至于買輪組以后，不調(diào)整會(huì)造成危險(xiǎn)或培林的損毀。

　　買輪組的時(shí)候就會(huì)附有專門的調(diào)整工具。這種工具有防止培林被所太緊而壞調(diào)的機(jī)制。

　　MAVIC QRM調(diào)整工具

　　動(dòng)手調(diào)整

　　調(diào)整時(shí)，首先要將輪組裝到車架（前叉）上面，再將快拆鎖上合適的力量，不要過緊或過松。

　　可以看到花鼓的右邊有幾個(gè)小洞。

　　再用工具的凸出點(diǎn)去調(diào)整即可。

　　前輪是與前叉配合。調(diào)整到適合得松緊度。

　　后輪則是與車架配合，后輪的照片比較可以看清楚花鼓上的凹點(diǎn)。

　　如何才知道是否有鎖到合適的力量呢？

　　假使所的過緊，可以很明顯發(fā)現(xiàn)輪組越來越難轉(zhuǎn)動(dòng)。越來越不順。

　　假使所的太松，輪組轉(zhuǎn)起來會(huì)變得很順，但是也會(huì)左右搖擺。

　　所以調(diào)整的時(shí)，所謂合適的松緊度，用手去晃輪組的時(shí)候，輪組是不會(huì)向左右晃動(dòng)的就可以了。

　　要用手去推推看，輪組是否會(huì)向左右兩邊晃動(dòng)，如果會(huì)就是太松了。假使調(diào)的過緊的話，轉(zhuǎn)動(dòng)會(huì)很澀，過于緊會(huì)讓軸承增加磨損，從而減少軸承的使用壽命。
